Referring keyword PHP script?

[Voodoo]

Does anyone have that snippet of code that was floating around that captures the referring keyword from the search results on Google / Yahoo etc... and displays the keyword/phrase on the landing page?

If so, please post.

Thanks.

heres a really simple one , im sure there are better ways to do it

<?php
$ref=@$HTTP_REFERER; 
$exr = explode("q=",$ref);
$exk = explode("&",$exr[1]);
$sekeyword = "$exk[0]";
echo $sekeyword;
?>
