Extract info in url problem

Hi guys/gals,

I have been searching and searching but found nothing that I could use so I'm now asking in here.

Can someone be so kind and tell me how a php script that takes an url and strip off some info and then take the rest and paste it into the meta keywords/description tags?

For example http://www.somesite.com/?santa+klaus it should take santa & Klaus and add it to the meta tag when the page loads.

Can this be done easily?

Thanks in advanced for all suggestions!

Searching for <? echo $_GET['s']; ?>

Result: Searching for Basshunter.

 

<?php
$url='http://test.tld/?first=First+Content&second=Second+Content&third=Third+Content';
$_meta='';
foreach($_GET as $key) $_meta.=$key;
echo '<meta name="keywords" content="'.$_meta.'" />';
?>

Try this and tell me how it works. This should be put where you want the meta keywords to be shown (in the head tags, of course).
