PHP can be compiled as a shared module of a web server (such as Apache) or as a CGI executable. If you are using a web server that is not supported by PHP, or if you want to execute PHP scripts in your command shell rather than on a web page, you should compile PHP as a CGI executable. Otherwise, if you want to install PHP to operate in conjunction with Apache, compile it as an Apache module.
