Hello!

> preg_match("/PPC/i", "$agent")
^ ^

IMO you should use >$agent< instead of >"$agent"<.
Furthermore you are only doing a check whether one string is in another.
Use stripos (PHP5), strpos in combinanation with strtolower or stristr
for this.
IIRC the second is the fastest for PHP4.

if (strpos(strtolower($agent), 'ppc') !== false) {
// ...
}

http://php.net/strpos
http://php.net/stripos
http://php.net/strstr
http://php.net/stristr
http://php.net/strtolower
