// You can use "parse_str" to parse the URL Query to an Array
$query = parse_url($url, PHP_URL_QUERY);
$queryArray = array();
parse_str($query, $queryArray);
var_dump($queryArray);  // array('argument' => 'value')

$url = $_SERVER['REQUEST_URI'];

if (!strpos($url,'mysql')) {
echo 'No mysql.'; //swapped with other echo statement
} else {
echo 'Mysql exists.';
