Syntax Highlighting in script

I'm trying to highlight php syntax in a (different) PHP script. And I must be doing something horribly wrong, cause it won't work at all. I'm using the CGI version of PHP, and what I'm doing is; passthru("/usr/bin/local/php -s /path"); doesn't work. Tried it with a -q too, nope. Tried using a Perl script to execute it for the PHP, nu-uh. I also tried system() rather than passthru. The output I'm getting is a lot of "X-Powered-By: PHP/4.0.3pl1 Content-type: text/html" and then eventually a failure to fork() message. When it's with a script that connects to an SQL server, it complains of a loss of connection. I'm outta ideas, and I hope there's an easy answer.
