Upgrading to PHP 5.3.5
5.3.5 is not fully backwards compatible with 5.2.x so ensure that you don't need any options from 5.2.x before upgrade.
Instructions below to upgrade PHP to 5.3.5
Please note these are not the official packages, and have been put together by rpms.famillecollet.com/ for RHEL5 distributions (thank you!). I have rebuilt these so they install for ClearOS with the addition of two RPM's (libedit and sqlite2).
Thefore please consider these as beta / testing quality.
WARNING: 5.3.x is not entirely backwards compatible with older versions of PHP. Therefore if your application / website / scripts do not specify compatibility then it may break!
If you are a website developer then you may want to review the changes between 5.2 and 5.3 here
You can also install many other PHP features through YUM.
YUM install php-*
YUM list php-* for all the available app you can add.
