This will give you the total number of & separated URL query parameters:
count(explode('&', $_SERVER['QUERY_STRING']))
If you only want unique parameters, use $_GET instead:
count($_GET)

thanks. on the basis of your idea i used count($_REQUEST) that worked too.
Retrieve them with $_GET. This should be enough.
Example:
// url: index.php?a=1&b=2&c=3
echo count($_GET); // 3 params, $_GET['a'], $_GET['b'], $_GET['c']
Note: you can also pass arrays in url ( check here ), and the whole array is counted once.

Your Common Sense
Good catch on arrays. Deleting mine in your favor
This will do the trick for you. Try this :
$total = count($_GET); echo $total;

If you only want the parameters in the URL, it's better to use $_GET. Since $_REQEUST contains the contents of $_GET, $_POST and $_COOKIE. see php.net
And if you want to know the number of parameters, you can get count the number of parameters that are in the URL using this: count($_GET).
