PHP need to trim all the $_POST variables

Question

Need you help in an unusal situation. I need to trim all the $_POST variables.

Is there any way I can do it at a single shot i.e., using a single function?

I

Answer 1

use array_walk with a custom function

$clean_values = array();
array_walk($_POST, 'sanitize_post');

function sanitize_post($item, $key)
{
    $clean_values[$key] = trim($item);
    //optional further cleaning ex) htmlentities
}

Answer 2

Simply use this:

array_walk($_POST, create_function('&$val', '$val = trim($val);')); 

and your $_POST is now trimmed.
