Just as a note to everyone, the recently shipped RHEL 5.6 breaks a usual release pattern of not upgrading software packages across major versions within a release. Now, PHP 5.3 will be included once your systems are updated to RHEL 5.6. This was done to ensure applications have little difficulty when upgrading to RHEL 6 this year.
This is just another reminder that we need to be diligent about making sure module are 5.3-compliant. You can find PHP 5.3-related issues here - https://drupal.org/project/issues/search/?issue_tags=PHP%205.3

1.88.1. RHEA-2011:0069: packages: php53
New php53 packages are now available for Red Hat Enterprise Linux 5.
PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.
The php53 packages provide the current PHP 5.3.x release series for Red Hat Enterprise Linux 5, superseding the 5.1.x series provided by the php packages.
php53 is provided for those users who wish to migrate to a more current PHP release. ( BZ#577688)
The php53 and php packages cannot be installed concurrently on the same system. In order to install the php53 packages, you must first remove the php packages if they are installed on your system.
All users requiring PHP 5.3 should install these new packages.
Thanks for the catch! I
Thanks for the catch! I didn't get that far into the release notes I guess.
I hate package names like this though. Now people are going to set php53 as dependencies, instead of php >= 5.3.
php package
Red Hat Linux release 6.3 now includes 5.3 as the default php package. Just did a yum install php and got version 5.3.3.
