[![build status] (https://dronie.osgeo.org/api/badges/geos/php-geos/status.svg?branch=master)] (https://dronie.osgeo.org/geos/php-geos?branch=master)

The code in this directory provides a PHP module to make use of functionalities of the [GEOS library] (http://geos.osgeo.org).

The bindings are linked to the C-API, for betters stability.

You need:

• PHP development files ( often found in packages named something like 'php5-dev' )

• GEOS development files ( often found in packages named something like 'libgeos-dev' )

git clone https://git.osgeo.org/gitea/geos/php-geos.git
cd php-geos
./autogen.sh
./configure
make # generates modules/geos.so

• PHP source files: download zip or clone from github
• PHP SDK ( https://github.com/Microsoft/php-sdk-binary-tools )
• Visual C++:
  • Visual C++ 14.0 (Visual Studio 2015) for PHP 7.0 or PHP 7.1.
  • Visual C++ 15.0 (Visual Studio 2017) for PHP 7.2, PHP 7.3 or PHP 7.4.
  • Visual C++ 16.0 (Visual Studio 2019) for master.
• GEOS Windows binaries (binary dll, includes and lib):
  • As part of OSGeo4W as part of the geos package.
  • As part of MS4W

Official instructions for compiling PHP extensions: https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2

1. Install OSGeo4w in C:\OSGeo4W64 and PHP-SDK in C:/php-sdk.

2. Invoke the starter script, for example for Visual Studio 2015 64-bit build, invoke phpsdk-vc15-x64.bat

3. Run the phpsdk_buildtree batch script which will create the desired directory structure:

    phpsdk_buildtree phpdev
   

   The phpsdk_buildtree script will create the path according to the currently VC++ version used and switch into the newly created directory

4. Extract the PHP source code to C:\php-sdk\phpdev\vX##\x##, where:

   vX## is the compiler version you are using (eq vc15 or vs16) x## is your architecture (x86 or x64) For example: C:\php-sdk\phpdev\vc15\x64\php-7.4.11-src In the same directory where you extracted the PHP source there is a deps directory. For example: C:\php-sdk\phpdev\vc15\x64\deps

5. Copy GEOS binaries from C:\OSGeo4W64 (bin, include and lib subdir) to C:\php-sdk\phpdev\vc15\x64\deps\

6. Copy (clone) code from this repository to C:\php-sdk\phpdev\vc15\x64\php-7.4.11-src\ext\geos

Run next commands to compile (see official php instruction):

c:\php-sdk\phpsdk-vc15-x64.bat
cd C:\php-sdk\phpdev\vc15\x64\php-7.4.11-src
buildconf
configure --disable-all --enable-cli --with-geos
nmake

Automated testing is executed on 'make check'.

You'll need phpunit installed for this to work. To install:

pear install --force --alldeps phpunit/phpunit

As root (or owner with write access to the directory returned by php-config --extension-dir), run:

make install

Copy php_geos.dll to extension directory and enable it in php.ini
