RHBA-2014:0618 - Bug Fix Advisory

Topic

Updated php54 packages that fix several bugs and add various enhancements are
now available for Red Hat Software Collections 1.1 for Red Hat Enterprise Linux.

Description

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP
Server. The php54 packages provide a recent stable release of PHP with PEAR
1.9.4, APC 3.1.15 and memcache 3.0.8 PECL extensions, and a number of additional
utilities.

The php54 packages have been upgraded to a later version that is required by Red
Hat Software Collections 1.1, which provides a number of bug fixes and
enhancements over the previous version.

This update also fixes the following bugs:

• Prior to this update, the "PHP_INI_SCAN_DIR" environment variable could only

be set to a single directory name. As a consequence, a Software Collection
dependent on the php54 collection was unable to use an additional directory for
configuration files. With this update, PHP has been patched to allow multiple
directory names in the "PHP_INI_SCAN_DIR" environment variable as a
colon-separated list and a dependent Software Collection is now able to use
multiple configuration directories. (BZ#1058162)

• Previously, when both Alternative PHP Cache (APC) and Zend OPcache were

enabled, a conflict could occur in the handling of "interned" strings between
the APC and OPcache extensions. Consequently, the PHP interpreter could
terminate unexpectedly with a segmentation fault. With this update, the APC
extension no longer handles "interned" strings in the default configuration and
the APC and OPcache can be enabled together concurrently without any negative
consequences. (BZ#1052178)

In addition, this update adds the following enhancement:

• Zend OPCache, an opcode cache, is now provided for PHP. Zend OPCache caches

pre-compiled PHP code in memory, and thus improves performance of web sites
running PHP applications. (BZ#1032929)

Users of php54 are advised to upgrade to these updated packages, which fix these
bugs and add these enhancements.
