Language improvements:

New tool:

  • PHP debugger provided in the new php-dbg subpackage (phpdbg command)

Benefit to Fedora

Provides the latest upstream PHP version.


  • Proposal owners:

Mass rebuild of all C extensions (repoquery --whatrequires 'php(api)')

  • Other developers:

(pure) PHP extension owners: ensure compatibility, usually this is detected by running upstream test suite, when exists.

PHP webapp owners: test

  • Release engineering:


  • Policies and guidelines:


Upgrade/compatibility impact

This new version should maintains compatibility with version 5.5.x.

How To Test

  • test PHP web applications available in the repository

Fedora 19/20 users can use backported packages from remi-php56 repository.

User Experience

Web developer will get the latest upstream PHP version.


Mass rebuild need: from repoquery --whatrequires 'php(zend-abi)'

Contingency Plan

According to upstream roadmap, 5.6.0 final should be released around June.

  • Contingency mechanism: Wait for 5.6.0RC1 for rawhide import, so we'll, at least, ship a RC. In case of big trouble, revert to F20 version (5.5.x).
  • Contingency deadline: June
  • Blocks release?: No
  • Blocks product?: No


Upstream documentation: Migrating from PHP 5.5.x to PHP 5.6.x (work in progress, should be ready for final)
