|
Changes to variable handling |
|
---------------------------- |
|
|
|
* Indirect variable, property and method references are now interpreted with |
|
left-to-right semantics. Some examples: |
|
|
|
$$foo['bar']['baz'] // interpreted as ($$foo)['bar']['baz'] |
|
$foo->$bar['baz'] // interpreted as ($foo->$bar)['baz'] |
|
$foo->$bar['baz']() // interpreted as ($foo->$bar)['baz']() |
|
Foo::$bar['baz']() // interpreted as (Foo::$bar)['baz']() |
|
|
|
To restore the previous behavior add explicit curly braces: |
|
|
|
${$foo['bar']['baz']} |
|
$foo->{$bar['baz']} |
|
$foo->{$bar['baz']}() |
|
Foo::{$bar['baz']}() |
|
|
|
* The global keyword now only accepts simple variables. Instead of |
|
|
|
global $$foo->bar; |
|
|
|
it is now required to write the following: |
|
|
|
global ${$foo->bar}; |
|
|
|
* Parentheses around variables or function calls no longer have any influence |
|
on behavior. For example the following code, where the result of a function |
|
call is passed to a by-reference function |
|
|
|
function getArray() { return [1, 2, 3]; } |
|
|
|
$last = array_pop(getArray()); |
|
// Strict Standards: Only variables should be passed by reference |
|
$last = array_pop((getArray())); |
|
// Strict Standards: Only variables should be passed by reference |
|
|
|
will now throw a strict standards error regardless of whether parentheses |
|
are used. Previously no notice was generated in the second case. |
|
|
|
* Array elements or object properties that are automatically created during |
|
by-reference assignments will now result in a different order. For example |
|
|
|
$array = []; |
|
$array["a"] =& $array["b"]; |
|
$array["b"] = 1; |
|
var_dump($array); |
|
|
|
now results in the array ["a" => 1, "b" => 1], while previously the result |
|
was ["b" => 1, "a" => 1]; |
|
|
|

|
* https://wiki.php.net/rfc/abstract_syntax_tree |
|
|
|
Changes to list() |
|
----------------- |
|
|
|
* list() will no longer assign variables in reverse order. For example |
|
|
|
list($array[], $array[], $array[]) = [1, 2, 3]; |
|
var_dump($array); |
|
|
|
will now result in $array == [1, 2, 3] rather than [3, 2, 1]. Note that only |
|
the **order** of the assignments changed, but the assigned values stay the |
|
same. E.g. a normal usage like |
|
|
|
list($a, $b, $c) = [1, 2, 3]; |
|
// $a = 1; $b = 2; $c = 3; |
|
|
|
will retain its current behavior. |
|
|
|
* Empty list() assignments are no longer allowed. As such all of the following |
|
are invalid: |
|
|
|
list() = $a; |
|
list(,,) = $a; |
|
list($x, list(), $y) = $a; |
|
|
|
* list() no longer supports unpacking strings (while previously this was only |
|
supported in some cases). The code |
|
|
|
$string = "xy"; |
|
list($x, $y) = $string; |
|
|
|
will now result in $x == null and $y == null (without notices) instead of |
|
$x == "x" and $y == "y". Furthermore list() is now always guaranteed to |
|
work with objects implementing ArrayAccess, e.g. |
|
|
|
list($a, $b) = (object) new ArrayObject([0, 1]); |
|
|
|
will now result in $a == 0 and $b == 1. Previously both $a and $b were null. |
|

|
|
|
Changes to foreach |
|
------------------ |
|
|
|
* Iteration with foreach() no longer has any effect on the internal array |
|
pointer, which can be accessed through the current()/next()/etc family of |
|
functions. For example |
|
|
|
$array = [0, 1, 2]; |
|
foreach ($array as &$val) { |
|
var_dump(current($array)); |
|
} |
|
|
|
will now print the value int(0) three times. Previously the output was int(1), |
|
int(2) and bool(false). |
|
|
|
* When iterating arrays by-value, foreach will now always operate on a copy of |
|
the array, as such changes to the array during iteration will not influence |
|
iteration behavior. For example |
|
|
|
$array = [0, 1, 2]; |
|
$ref =& $array; // Necessary to trigger the old behavior |
|
foreach ($array as $val) { |
|
var_dump($val); |
|
unset($array[1]); |
|
} |
|
|
|
will now print all three elements (0 1 2), while previously the second element |
|
1 was skipped (0 2). |
|
|
|
* When iterating arrays by-reference, modifications to the array will continue |
|
to influence the iteration. However PHP will now do a better job of |
|
maintaining a correct position in a number of cases. E.g. appending to an |
|
array during by-reference iteration |
|
|
|
$array = [0]; |
|
foreach ($array as &$val) { |
|
var_dump($val); |
|
$array[1] = 1; |
|
} |
|
|
|
will now iterate over the appended element as well. As such the output of this |
|
example will now be "int(0) int(1)", while previously it was only "int(0)". |
|
|
|
* Iteration of plain (non-Traversable) objects by-value or by-reference will |
|
behave like by-reference iteration of arrays. This matches the previous |
|
behavior apart from the more accurate position management mentioned in the |
|
previous point. |
|
|
|
* Iteration of Traversable objects remains unchanged. |
|
|
|

|
|
|
Changes to parameter handling |
|
----------------------------- |
|
|
|
* It is no longer possible to define two function parameters with the same name. |
|
For example, the following method will trigger a compile-time error: |
|
|
|
public function foo($a, $b, $unused, $unused) { |
|
// ... |
|
} |
|
|
|
Code like this should be changed to use distinct parameter names, for example: |
|
|
|
public function foo($a, $b, $unused1, $unused2) { |
|
// ... |
|
} |
|
|
|
* The func_get_arg() and func_get_args() functions will no longer return the |
|
original value that was passed to a parameter and will instead provide the |
|
current value (which might have been modified). For example |
|
|
|
function foo($x) { |
|
$x++; |
|
var_dump(func_get_arg(0)); |
|
} |
|
foo(1); |
|
|
|
will now print "2" instead of "1". This code should be changed to either |
|
perform modifications only after calling func_get_arg(s) |
|
|
|
function foo($x) { |
|
var_dump(func_get_arg(0)); |
|
$x++; |
|
} |
|
|
|
or avoid modifying the parameters altogether: |
|
|
|
function foo($x) { |
|
$newX = $x + 1; |
|
var_dump(func_get_arg(0)); |
|
} |
|
|
|
* Similarly exception backtraces will no longer display the original value that |
|
was passed to a function and show the modified value instead. For example |
|
|
|
function foo($x) { |
|
$x = 42; |
|
throw new Exception; |
|
} |
|
foo("string"); |
|
|
|
will now result in the stack trace |
|
|
|
Stack trace: |
|
#0 file.php(4): foo(42) |
|
#1 {main} |
|
|
|
while previously it was: |
|
|
|
Stack trace: |
|
#0 file.php(4): foo('string') |
|
#1 {main} |
|
|
|
While this should not impact runtime behavior of your code, it is worthwhile |
|
to be aware of this difference for debugging purposes. |
|
|
|
The same limitation also applies to debug_backtrace() and other functions |
|
inspecting function arguments. |
|

|
|
|
Changes to integer handling |
|
--------------------------- |
|
|
|
* Invalid octal literals (containing digits larger than 7) now produce compile |
|
errors. For example, the following is no longer valid: |
|
|
|
$i = 0781; // 8 is not a valid octal digit! |
|
|
|
Previously the invalid digits (and any following valid digits) were simply |
|
ignored. As such $i previously held the value 7, because the last two digits |
|
were silently discarded. |
|
|
|
* Bitwise shifts by negative numbers will now throw an ArithmeticError: |
|
|
|
var_dump(1 >> -1); |
|
// ArithmeticError: Bit shift by negative number |
|
|
|
* Left bitwise shifts by a number of bits beyond the bit width of an integer |
|
will always result in 0: |
|
|
|
var_dump(1 << 64); // int(0) |
|
|
|
Previously the behavior of this code was dependent on the used CPU |
|
architecture. For example on x86 (including x86-64) the result was int(1), |
|
because the shift operand was wrapped. |
|
|
|
* Similarly right bitwise shifts by a number of bits beyond the bit width of an |
|
integer will always result in 0 or -1 (depending on sign): |
|
|
|
var_dump(1 >> 64); // int(0) |
|
var_dump(-1 >> 64); // int(-1) |
|
|
|
Relevant RFC: https://wiki.php.net/rfc/integer_semantics |
|
|
|
Changes to string handling |
|
-------------------------- |
|
|
|
* Strings that contain hexadecimal numbers are no longer considered to be |
|
numeric and don't receive special treatment anymore. Some examples of the |
|
new behavior: |
|
|
|
var_dump("0x123" == "291"); // bool(false) (previously true) |
|
var_dump(is_numeric("0x123")); // bool(false) (previously true) |
|
var_dump("0xe" + "0x1"); // int(0) (previously 16) |
|
|
|
var_dump(substr("foo", "0x1")); // string(3) "foo" (previously "oo") |
|
// Notice: A non well formed numeric value encountered |
|
|
|
filter_var() can be used to check if a string contains a hexadecimal number |
|
or convert such a string into an integer: |
|
|
|
$str = "0xffff"; |
|
$int = filter_var($str, FILTER_VALIDATE_INT, FILTER_FLAG_ALLOW_HEX); |
|
if (false === $int) { |
|
throw new Exception("Invalid integer!"); |
|
} |
|
var_dump($int); // int(65535) |
|
|
|
* Due to the addition of the Unicode Codepoint Escape Syntax for double-quoted |
|
strings and heredocs, "\u{" followed by an invalid sequence will now result in |
|
an error: |
|
|
|
$str = "\u{xyz}"; // Fatal error: Invalid UTF-8 codepoint escape sequence |
|
|
|
To avoid this the leading backslash should be escaped: |
|
|
|
$str = "\\u{xyz}"; // Works fine |
|
|
|
However, "\u" without a following { is unaffected. As such the following code |
|
won't error and will work the same as before: |
|
|
|
$str = "\u202e"; // Works fine |
|
|
|

|
* https://wiki.php.net/rfc/unicode_escape |
|
|
|
Changes to error handling |
|
------------------------- |
|
|
|
* There are now two exception classes: Exception and Error. Both classes |
|
implement a new interface Throwable. Type hints in exception handling code |
|
may need to be changed to account for this. |
|
|
|
* Some fatal errors and recoverable fatal errors now throw an Error instead. |
|
As Error is a separate class from Exception, these exceptions will not be |
|
caught by existing try/catch blocks. |
|
|
|
For the recoverable fatal errors which have been converted into an exception, |
|
it is no longer possible to silently ignore the error from an error handler. |
|
In particular, it is no longer possible to ignore type hint failures. |
|
|
|
* Parser errors now generate a ParseError that extends Error. Error |
|
handling for eval()s on potentially invalid code should be changed to catch |
|
ParseError in addition to the previous return value / error_get_last() |
|
based handling. |
|
|
|
* Constructors of internal classes will now always throw an exception on |
|
failure. Previously some constructors returned NULL or an unusable object. |
|
|
|
* The error level of some E_STRICT notices has been changed. |
|
|
|

|
* https://wiki.php.net/rfc/reclassify_e_strict |
|
|
|
Other language changes |
|
---------------------- |
|
|
|
* Removed support for static calls to non-static methods from an incompatible |
|
$this context. In this case $this will not be defined, but the call will be |
|
allowed with a deprecation notice. An example: |
|
|
|
class A { |
|
public function test() { var_dump($this); } |
|
} |
|
|
|
// Note: Does NOT extend A |
|
class B { |
|
public function callNonStaticMethodOfA() { A::test(); } |
|
} |
|
|
|
(new B)->callNonStaticMethodOfA(); |
|
|
|
// Deprecated: Non-static method A::test() should not be called statically |
|
// Notice: Undefined variable $this |
|
NULL |
|
|
|
Note that this only applies to calls from an incompatible context. If class B |
|
extended from A the call would be allowed without any notices. |
|
|
|
* It is no longer possible to use the following class, interface and trait names |
|
(case-insensitive): |
|
|
|
bool |
|
int |
|
float |
|
string |
|
null |
|
false |
|
true |
|
|
|
This applies to class/interface/trait declarations, class_alias() and use |
|
statements. |
|
|
|
Furthermore the following class, interface and trait names are now reserved |
|
for future use, but do not yet throw an error when used: |
|
|
|
resource |
|
object |
|
mixed |
|
numeric |
|
|
|
* The yield language construct no longer requires parentheses when used in an |
|
expression context. It is now a right-associative operator with precedence |
|
between the "print" and "=>" operators. This can result in different behavior |
|
in some cases, for example: |
|
|
|
echo yield -1; |
|
// Was previously interpreted as |
|
echo (yield) - 1; |
|
// And is now interpreted as |
|
echo yield (-1); |
|
|
|
yield $foo or die; |
|
// Was previously interpreted as |
|
yield ($foo or die); |
|
// And is now interpreted as |
|
(yield $foo) or die; |
|
|
|
Such cases can always be resolved by adding additional parentheses. |
|
|
|

|
(RFC: https://wiki.php.net/rfc/remove_alternative_php_tags) |
|
. Removed support for assigning the result of new by reference. |
|
. Removed support for scoped calls to non-static methods from an incompatible |
|
$this context. See details in https://wiki.php.net/rfc/incompat_ctx. |
|
. Removed support for #-style comments in ini files. Use ;-style comments |
|
instead. |
|
. $HTTP_RAW_POST_DATA is no longer available. Use the php://input stream instead. |
|
|
|
Standard library changes |
|
======================== |
|
|
|
. substr() now returns an empty string instead of FALSE when the truncation happens on boundaries. |
|
. call_user_method() and call_user_method_array() no longer exists. |
|
. ob_start() no longer issues an E_ERROR, but instead an E_RECOVERABLE_ERROR in case an |
|
output buffer is created in an output buffer handler. |
|
. The internal sorting algorithm has been improved, what may result in |
|
different sort order of elements that compare as equal. |
|
. Removed dl() function on fpm-fcgi. |
|
. setcookie() with an empty cookie name now issues a WARNING and doesn't send an empty set-cookie header line anymore. |
|
|
|
Other |
|
===== |
|
|
|
- Curl: |
|
. Removed support for disabling the CURLOPT_SAFE_UPLOAD option. All curl file |
|
uploads must use the curl_file / CURLFile APIs. |
|
|
|
- Date: |
|
. Removed $is_dst parameter from mktime() and gmmktime(). |
|
|
|
- DBA |
|
. dba_delete() now returns false if the key was not found for the inifile |
|
handler, too. |
|
|
|
- GMP |
|
. Requires libgmp version 4.2 or newer now. |
|
. gmp_setbit() and gmp_clrbit() now return FALSE for negative indices, making |
|
them consistent with other GMP functions. |
|
|
|
- Intl: |
|
. Removed deprecated aliases datefmt_set_timezone_id() and |
|
IntlDateFormatter::setTimeZoneID(). Use datefmt_set_timezone() and |
|
IntlDateFormatter::setTimeZone() instead. |
|
|
|
- libxml: |
|
. Added LIBXML_BIGLINES parser option. It's available starting with libxml 2.9.0 |
|
and adds suppport for line numbers >16-bit in the error reporting. |
|
|
|
- Mcrypt |
|
. Removed deprecated mcrypt_generic_end() alias in favor of |
|
mcrypt_generic_deinit(). |
|
. Removed deprecated mcrypt_ecb(), mcrypt_cbc(), mcrypt_cfb() and mcrypt_ofb() |
|
functions in favor of mcrypt_encrypt() and mcrypt_decrypt() with an |
|
MCRYPT_MODE_* flag. |
|
|
|
- Session |
|
. session_start() accepts all INI settings as array. e.g. ['cache_limiter'=>'private'] |
|
sets session.cache_limiter=private. It also supports 'read_and_close' which closes |
|
session data immediately after read data. |
|
. Save handler accepts validate_sid(), update_timestamp() which validates session |
|
ID existence, updates timestamp of session data. Compatibility of old user defined |
|
save handler is retained. |
|
. SessionUpdateTimestampHandlerInterface is added. validateSid(), updateTimestamp() |
|
is defined in the interface. |
|
. session.lazy_write(default=On) INI setting enables only write session data when |
|
session data is updated. |
|
|
|
- Opcache |
|
. Removed opcache.load_comments configuration directive. Now doc comments |
|
loading costs nothing and always enabled. |
|
|
|
- OpenSSL: |
|
. Removed the "rsa_key_size" SSL context option in favor of automatically |
|
setting the appropriate size given the negotiated crypto algorithm. |
|
. Removed "CN_match" and "SNI_server_name" SSL context options. Use automatic |
|
detection or the "peer_name" option instead. |
|
|
|
- PCRE: |
|
. Removed support for /e (PREG_REPLACE_EVAL) modifier. Use |
|
preg_replace_callback() instead. |
|
|
|

|
. Removed PGSQL_ATTR_DISABLE_NATIVE_PREPARED_STATEMENT attribute in favor of |
|
ATTR_EMULATE_PREPARES. |
|
|
|
- Standard: |
|
. Removed string category support in setlocale(). Use the LC_* constants |
|
instead. |
|
. Removed set_magic_quotes_runtime() and its alias magic_quotes_runtime(). |
|
|
|
- JSON: |
|
. Rejected RFC 7159 incompatible number formats in json_decode string - |
|
top level (07, 0xff, .1, -.1) and all levels ([1.], [1.e1]) |
|
. Calling json_decode with 1st argument equal to empty PHP string or value that |
|
after casting to string is empty string (NULL, FALSE) results in JSON syntax error. |
|
|
|
- Stream: |
|
. Removed set_socket_blocking() in favor of its alias stream_set_blocking(). |
|
|
|
- XSL: |
|
. Removed xsl.security_prefs ini option. Use XsltProcessor::setSecurityPrefs() |
|
instead. |
|
|
|
======================================== |
|
2. New Features |
|
======================================== |
|
|
|
- Core |
|
. Added group use declarations. |
|
(RFC: https://wiki.php.net/rfc/group_use_declarations) |
|
. Added null coalesce operator (??). |
|
(RFC: https://wiki.php.net/rfc/isset_ternary) |
|
. Support for strings with length >= 2^31 bytes in 64 bit builds. |
|
. Closure::call() method added (works only with userland classes). |
|
. Added \u{xxxxxx} Unicode Codepoint Escape Syntax for double-quoted strings |
|
and heredocs. |
|
. define() now supports arrays as constant values, fixing an oversight where |
|
define() did not support arrays yet const syntax did. |
|
. Added the comparison operator (<=>), aka the spaceship operator. |
|
(RFC: https://wiki.php.net/rfc/combined-comparison-operator) |
|
. Added the yield from operator for delegating Generators like coroutines. |
|
(RFC: https://wiki.php.net/rfc/generator-delegation) |
|
. Reserved keywords can now be used in various new contexts. |
|
(RFC: https://wiki.php.net/rfc/context_sensitive_lexer) |
|
. Added support for scalar type declarations and strict mode using |
|
declare(strict_types=1) (RFC: https://wiki.php.net/rfc/scalar_type_hints_v5) |
|
. Added support for cryptographically secure user land RNG |
|
(RFC: https://wiki.php.net/rfc/easy_userland_csprng) |
|
|
|
- Opcache |
|
. Added second level file based opcode cache. It may be enabled by setting |
|
opcache.file_cache=<DIR> configuration directive in php.ini. The second |
|
level cache may improve performance when SHM is full, at server restart or |
|
SHM reset. In addition, it's possibe to use file cache without SHM at all, |
|
using opcache.file_cache_only=1 (this may be useful for sharing hosting), |
|
and disable file cache consistency check, to speedup loading at the cost of |
|
safety, using opcache.file_cache_consistency_checks=0. |
|
. Added ability to move PHP code pages (PHP TEXT segment) into HUGE pages. |
|
It's possible to enable/disable this feature in php.ini through |
|
opcache.huge_code_pages=0/1. OS should be configured to provide huge pages. |
|
. Added Windows only opcache.file_cache_fallback=1 ini option, which implies |
|
the implemented fallback mechanism. When OPcache was not able to reattach |
|
the shared memory segment to the desired address and opcache.file_cache |
|
is on, opcache.file_cache_only=1 will be automatically enforced. |
|
|
|
- OpenSSL |
|
. Added "alpn_protocols" SSL context option allowing encrypted client/server |
|
streams to negotiate alternative protocols using the ALPN TLS extension when |
|
built against OpenSSL 1.0.2 or newer. Negotiated protocol information is |
|
accessible through stream_get_meta_data() output. |
|
|
|
- Reflection |
|
. Added a ReflectionGenerator class (yield from Traces, current file/line, |
|
etc.) |
|
. Added a ReflectionType class to better support the new return type and |
|
scalar type declarations features. The new ReflectionParameter::getType() |
|
and ReflectionFunctionAbstract::getReturnType() methods both return an |
|
instance of ReflectionType. |
|
|
|
- Stream: |
|
. New Windows only stream context options was added to allow blocking reads |
|
on pipes. To enable it, pass array("pipe" => array("blocking" => true)) |
|
when creating the stream context. Be aware, that this option can under |
|
circumstances cause dead locks on the pipe buffer. However it can be useful |
|
in several CLI use case scenarios. |
|
|
|
======================================== |
|
3. Changes in SAPI modules |
|
======================================== |
|
|
|
- FPM |
|
. Fixed bug #65933 (Cannot specify config lines longer than 1024 bytes). |
|
. Listen = port now listen on all addresses (IPv6 and IPv4-mapped). |
|
|
|
======================================== |
|
4. Deprecated Functionality |
|
======================================== |
|
|
|
- Core |
|
. PHP 4 style constructors, where the constructor name is the same as the |
|
class name, are now deprecated. |
|
. Static calls to non-static methods are now deprecated. |
|
|
|
- OpenSSL |
|
. The "capture_session_meta" SSL context option is now deprecated. Meta |
|
data concerning active crypto on a stream resource is now accessible |
|
through the return result from stream_get_meta_data(). |
|
|
|
======================================== |
|
5. Changed Functions |
|
======================================== |
|
|
|
- unserialize(): |
|
. Added second parameter for unserialize function |
|
(RFC: https://wiki.php.net/rfc/secure_unserialize) allowing to specify |
|
acceptable classes: |
|
unserialize($foo, ["allowed_classes" => ["MyClass", "MyClass2"]]); |
|
|
|
- proc_open(): |
|
. The maximum number of pipes used by proc_open() was previously limited by |
|
hardcoded value of 16. This limit is now removed and the number of pipes is |
|
effectively limited by the amount of memory available to PHP. |
|
. New Windows only configuration option "blocking_pipes" can be used to |
|
force blocking reads on child process pipes. This covers several |
|
edge cases in CLI usage however can lead to dead locks. Also, this |
|
correlates with the new stream context options for pipes. |
|
|
|
- array_column(): |
|
The function now supports an array of objects as well as two-dimensional |
|
arrays. Only public properties are considered, and objects that make use of |
|
__get() for dynamic properties must also implement __isset(). |
|
|
|
- stream_context_create() |
|
It accepts now a Windows only configuration |
|
array("pipe" => array("blocking" => <boolean>)) which forces blocking reads |
|
on pipes. This option should be used carefully because due to the |
|
platform restrictions dead locks on pipe buffers are possible. |
|
|
|
- dirname() |
|
A new optional argument ($levels) allow to go up various times |
|
dirname(dirname($foo)) => dirname($foo, 2); |
|
|
|
- debug_zval_dump |
|
It prints now "int" instead of "long", and "float" instead of "double". |
|
|
|
- getenv() |
|
Since 7.0.9, getenv() has optional second parameter, making it only |
|
consider local environment and not SAPI environment if true. |
|
|
|
======================================== |
|
6. New Functions |
|
======================================== |
|
|
|
- GMP |
|
. Added gmp_random_seed(). |
|
|
|
- PCRE: |
|
. Added preg_replace_callback_array function |
|
(RFC: https://wiki.php.net/rfc/preg_replace_callback_array) |
|
|
|
- Standard |
|
. Added intdiv() function for integer division. |
|
. Added error_clear_last() function to reset error state. |
|
|
|
- Zip: |
|
. Added ZipArchive::setCompressionIndex() and ZipArchive::setCompressionName() |
|
for setting the compression method. |
|
|
|
- Zlib: |
|
. Added deflate_init(), deflate_add(), inflate_init(), inflate_add() |
|
functions allowing incremental/streaming compression/decompression. |
|

|
https://wiki.php.net/rfc/remove_deprecated_functionality_in_php7 |
|
|
|
NOTE: NSAPI was not voted in the RFC, however it was removed afterwards. It turned |
|
out, that the corresponding SDK isn't available anymore. |
|
|
|
======================================== |
|
9. Other Changes to Extensions |
|
======================================== |
|
|
|
- Mhash |
|
Mhash is not an extension anymore, use function_exists("mhash") to check whether |
|
it is avaliable. |
|
|
|
- GD |
|
The bundled libgd requires libwebp instead of libvpx for the WebP functionality. |
|
|
|
- Openssl |
|
minimum supported OpenSSL version series was raised to 0.9.8 |
|
|
|
======================================== |
|
10. New Global Constants |
|
======================================== |
|
|
|
- Core |
|
. PHP_INT_MIN added. |
|
|
|
- PCRE |
|
. This error constant is added to signal errors due to stack size limitations |
|
when PCRE JIT support is enabled: |
|
. PREG_JIT_STACKLIMIT_ERROR |
|
|
|
- Zlib |
|
. These constants are added to control flush behavior with the new |
|
incremental deflate_add() and inflate_add() functions: |
|
. ZLIB_NO_FLUSH |
|
. ZLIB_PARTIAL_FLUSH |
|
. ZLIB_SYNC_FLUSH |
|
. ZLIB_FULL_FLUSH |
|
. ZLIB_BLOCK |
|
. ZLIB_FINISH |
|
|
|
- GD |
|
. T1Lib support removed, thus lifting the optional dependency on T1Lib, the |
|
following is therefore not available anymore: |
|
|
|
Functions: |
|
- imagepsbbox() |
|
- imagepsencodefont() |
|
- imagepsextendedfont() |
|
- imagepsfreefont() |
|
- imagepsloadfont() |
|
- imagepsslantfont() |
|
- imagepstext() |
|
|
|
Resources: |
|
- 'gd PS font' |
|
- 'gd PS encoding' |
|
|
|
- Zip |
|
. Filename encoding flags, as of 7.0.8 |

|
|
|
======================================== |
|
11. Changes to INI File Handling |
|
======================================== |
|
|
|
- Core |
|
. Removed asp_tags ini directive. Trying to enable it will result in a fatal |
|
error. |
|
. Removed always_populate_raw_post_data ini directive. |
|
|
|
======================================== |
|
12. Windows Support |
|
======================================== |
|
|
|
- Core |
|
. Support for native 64 bit integers in 64 bit builds. |
|
. Support for large files in 64 bit builds. |
|
. Support for getrusage() |
|
|
|
- ftp |
|
. The ftp extension is always shipped shared |
|
. For SSL support, the dependency on the openssl extension was abolished. Instead |
|
it depends alone on the openssl library. If it's present at the compile time, |
|
ftp_ssl_connect() is enabled automatically. |
|
|
|
- imap |
|
. Static building of ext/imap is disabled |
|
|
|
- odbc |
|
. The odbc extension is always shipped shared |
|
|
|
======================================== |
|
13. Other Changes |
|
======================================== |
|
|
|
- Core |
|
. Instead of being undefined and platform-dependent, NaN and Infinity will |
|
always be zero when cast to integer. |
|
. Calling a method on a non-object now raises a catchable error instead of a |
|
fatal error; see: https://wiki.php.net/rfc/catchable-call-to-member-of-non-object |
|
. Error messages for zend_parse_parameters, type hints and conversions now |
|
always say "integer" and "float" instead of "long" and "double". |
|
. Output buffering now continues to work for an aborted connection if |
|
ignore_user_abort is set to true. |
|
. Zend Extensions API was extended with zend_extension.op_array_persist_calc() |
|
and zend_extensions.op_array_persist() handlers. They allow to store (or |
|
reset) associated with op_array addition information in Opcache Shared |
|
Memory. |
|
. zend_internal_function.reserved[] array was introduced to allow association |
|
of aditional information with internal functions. In PHP-5 it was possible |
|
to use zend_function.op_array.reserved[] even for internal functions, but |
|
now we don't allocate extra space. |
