[CentOS] PHP 4.3.10 on CentOS 4 or CentOS 5

Hi Everyone,

I am in a fix with an installation for a client where I need PHP
version 4.3.10 or above (4.3.x, but not PHP 5). The application we are
trying to run will not run on PHP 5.

CentOS 4.5 provides PHP 4.3.9, is there a quick an easy way to have
PHP 4.3.10 available on either CentOS 4.5 or CentOS 5

Any pointers will be greatly appreciated.
