[SOLVED] $HTTP_REFERER and Explode

[TecTao]

This may seem like a simple question but I can't seem to get a handle on the use of explode.

I have a simple script on my pages that emails me with a visitro IP and search info.  But the search info collected from $HTTP_REFERER sends the search phrase with "+" sign between the words and a bunch of stuff before and after the serch string.

I want to remove all the stuff and display only the search terms.

Any suggestions?

why don't you use $_GET?

He can't use $_GET because it's the referrer, not the script URL.

[code=php:0]$query = preg_replace('|[^?]*\?|', '', $_SERVER['HTTP_REFERER']);
$query_bits = explode('&', $query);
foreach ($query_bits as $varval) {
  list($var, val) = explode('=', $varval);
  if ($var == 'q') {
    # Do something with val
  }
}[/code]


That ought to work, assuming the search engine does "q=search+term".  The preg_replace is to cut off everything before the question mark.
