PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. The rh-php56 packages provide a recent stable release of PHP with PEAR 1.9.5 and enhanced language features including constant expressions, variadic functions, arguments unpacking, and the interactive debuger. The memcache, mongo, and XDebug extensions are also included. The rh-php56 Software Collection has been upgraded to version 5.6.25, which provides a number of bug fixes and enhancements over the previous version. Security Fixes in the rh-php56-php component have been added.
