Tool to downgrade your PHP codebase from PHP 5.4+ to PHP 5.3. Built on top of galapagos.

Consider including php5.3-compatibility package in your project, which includes JsonSerializable and SessionHandlerInterface.

You may have to manually fix some remaining problems, usually they're quite simple.

Use it when you have a PHP 5.4+ codebase and just can't upgrade your client's infrastructure.

• Convert new array syntax to old one. ([1,2,3] to array(1,2,3))
• Inject traits code into classes that use them.
• Analyze every vendor's composer.json and convert them if it's needed
• Downgrade function calls with different signature.
  • stream_context_create
  • session_set_save_handler
• Custom node transformations

./php-code-downgrade [path-to-downgrade]

Using custom node transformations:

./php-code-downgrade [path-to-downgrade] -t transformations/phalanger
