This snippet extracts the keywords or search phrases from a Google referral. It also sets variables for the search engine, date and web page which received the referral if you want to log the data to a file or database. The variables are $engine, $finalphrase (keyword phrase), $page(referred web page), and $date.

unset ($engine); 

$string = $HTTP_REFERER;

if (strstr($string, "google")){

   if (strstr($string, "search?")) {

      $engine = "google";

      $substr = explode("q=", $string);

      $substr = explode("&", $substr[1]);

      $kwphrase = eregi_replace("(%[0-9a-f]{2})+", " ", $substr[0]);

      $kwphrase = eregi_replace("(\+)+", " ", $kwphrase);

      $finalphrase = strtolower($kwphrase); 

   }

$to = explode("/", $PHP_SELF);

   $arraynum = count ($to);

   $page = $to[$arraynum-1];

   $date = date("Y-n-j") ;
