Greetings
In the attempt to upgrade the technology stack on CentOS 5 from stock PHP to PHP53 I have made some progress.
Much thanks to all respondents, especially Jesus.
One repository that provides a complete set of builds and seems to fulfill both PHP and PHP53 requirements is the IUS one: http://iuscommunity.org/ Repos here: http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/i386/repoview/
One reference to several discussions covering this topic are available here: https://www.centos.org/modules/newbb/viewtopic.php?topic_id=30881
Using the IUS PHP53 rpms allows for the rpm re-installation of drupal6, phpmyadmin, and squirrelmail.
However, with Squirrelmail there is one critical issue. Via one of its plugins, Squirellmail provides an html email editor. With the upgrade to PHP53, the editor continues to work. However, the html email that is composed using this functionality is received empty.
Reverting back to the original CentOS PHP packages re-enables this functionality.
Is there a solution to this issue?
Much thanks.
One (secondary) thing.
In order to support yum updates from the IUS repository, how do I load the appropriate file?
Much thanks.
