PHP: How to check total no. parameters in URL?

Question

i am retrieving the parameters using $_REQUEST. Is there a way of finding total no. of parameters in URL instead of retrieving each one and then counting ?

what abount count($_GET) count($_POST) or count($_REQUEST) isnt working for you? — x4rf41, Jan 18 '13 at 11:43

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. – Reena Parekh Jan 18 '13 at 12:03

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.

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).
