Our hosting services (linux and windows) support PHP 5.2 or PHP 5.3.

All servers have PHP 5.2.6 or later installed as default version.

Plesk windows hosting support PHP 5.2 5.3 5.4. User can choose PHP version in Plesk control panel.

User can change PHP version in PHP Configuration (linux hosting with Cpanel).

On some linux servers you may be able to customize PHP with this method:

Use .htaccess to add Apache Handler

Login cpanel, find apache handler option and add the following handler for .php extension

application/x-httpd-php5

( this will add a new line in .htaccess file - AddHandler aplication/x-httpd-php5 .php )
