Retrieve data from $_GET array

$q = explode("&",$_SERVER["QUERY_STRING"]);
foreach ($q as $qi)
{
if ($qi != "")
{
$qa = explode("=",$qi);
list ($key, $val) = $qa;
if ($val)
$$key = urldecode($val);
}
}

This code is similar to previous code but this one is for $_GET global variables. Good luck with your programming !!
