Checking numbers in an array

[MemphiS]

Problem is i have users select 8 numbers and then submit the data and i need to check that each of the 8 numbers are different.. I know its a simple problem, but im afraid i just cant think tonight

<?php

if ($_POST['radio']){

$c = 0;

$a = array();

foreach(intval($_POST['radio']) as $value) {

if ($c < {

if (!in_array($value, $a)){

$a[] = $value;

$c++;

}}}}
?>

 

Duno if that will work but I thaught I'd have a crack

<?php
if(count($numArray) != count(array_unique($numArray)))
{
   echo 'error! dupe values in array!';
}
?>
