PHP
Unlike Apache's mod_php, which embeds the PHP engine inside web server processes, LiteSpeed Web Server talks to standalone PHP engine processes via LSAPI interface. You will need to install PHP either through RPMs or compiling from Source code, create a PHP external application mapping to the installed PHP Binary and set a script handler mapping to the PHP external application.
