No matter what OS you have installed you need to compile / install php as a CGI because when you have php as a CGI you have a binary you can execute from anywhere like a command prompt.
If you use a unix like OS you should do:/path/to/php -/path/to/script.phpForwindowsOS's do:
c:\path\to\php.exe -f c:\path\to\script.php.
The parameter -f is put on because we want to parse a file, the -f also implies -q which means you dont get any HTTP header output which in most cases is usefull when making command line scripts.

Qouted from the php manual:
Unlike include(), require() will always read in the target file, even if the line it's on never executes. If you want to conditionally include a file, use include(). The conditional statement won't affect the require(). However, if the line on which the require() occurs is not executed, neither will any of the code in the target file be executed.
In PHP 3, it is possible to execute a return statement inside a require()ed file, as long as that statement occurs in the global scope of the require()ed file. It may not occur within any block (meaning inside braces ({}). In PHP 4, however, this ability has been discontinued. If you need this functionality, see include().
