PHP version & phpinfo()
DreamHost currently allows several PHP configurations. In the user Control Panel you can choose between PHP4 and PHP5 running as a CGI application (with optional FastCGI support). While it's no longer officially supported you currently still have the possibility to have PHP running as an Apache module (mod_php).
Finally you have the option to compile your own custom PHP with the exact version of PHP you wish and with any module you require.
