Aprelium is not responsible for providing PHP packages, they do this merely as a convenience to forum users.
The PHP package you get from php.net works perfectly. When installing, select the extensions you require, and make sure to select "Other CGI" for the servers, not IIS or Apache, or "No server now."
This will extract the php-cgi.exe, which you'll need to interface with Abyss. I'm assuming you're looking for a Windows platform, since Linux archives have never originated from this site, and are generally compiled on a per-server basis per requirements. I typically use Non-Thread Safe VS6, however you may find better results with one of the other available packages.

Additionally, PHP 5.2.x is not unsupported, with the 5.2.14 release coming out on July 22nd. You should consider PHP 5.3.3, but I'm willing to bet you'll regret it if you're not an experienced PHP developer.
