Question

I am trying to get this form to:

if any $_POST vars equals any other of the $_POST vars throw an error.

if it was just a few it wouldnt be an issue but I have about 20 or so
so if i wanted to do it I would have to go like

    <?php 
    if($_POST['input1']==$_POST['input2'] || $_POST['input1']==$_POST['input3']){
die('whatever');
}

    ?>

But that’s not good coding (and it would take forever)
I thought about arrays and different ways…

but I am brain dead atm so I thought I could get some help..
thanks in advance

ps it would be nice to do it in PHP (server side) but Jquery is always an option.

function testPost(){
foreach ($_POST as $keya=>$vala){
    foreach($_POST as $keyb=>$valb){
        if ($keya==$keyb){
            continue;
        } else {
            if ($vala == $valb){
                 return FALSE;
            }
        }
    }
}
return TRUE;
}
