pattern matching in refering url

[oilman]

I am trying to write a cookie (php) that sets a value based on the referrer string. ie: if user used the search phrase 'blue widgets' then value is set to one or if user used search phrase 'red widgets' then value is set to 2 and do on.

Little help? :)

Something along these lines should do the trick:

if (preg_match [php.net]("'red'", $_SERVER['REFERER'])) {
setcookie [php.net]();
} else {
setcookie [php.net]();
}

thanks - I was playing around with preg_match earlier but didn't have the syntax right. I'll give it a whirl right away.
