To unique an array in newer versions of php - i've found this snippet useful:

<?php
// $old[0] = 1
// $old[1] = 1
// $old[2] = 2
// $old[3] = 1
// $old[4] = 2

$new = array();

for($i=0;$i<count($old);++$i){

	if(in_array($old[$i], $new) != "true"){
		$new[] = $old[$i];
	}
}

//$new now contains:
//
//$new[0] = 1
//$new[1] = 2
?>
