How to get a subset of $_POST array with keys starting with a prefix

Question

Let\'s say my $_POST variable looks like:

 65
    [action] => editpost
    [originalaction] => editpo         


        

Answer 1

Another method:

$formVars = $_POST;
foreach ($formVars as $key=>$value) {
    if (strpos($key, 'empl_')===false) 
        unset($formVars[$key]);
}
