I would do it with a small class like this:

<?php
class mac{
var $mac='';
var $is_valid = false;
function mac($mac){
$mac = preg_replace('/[^0-9A-F]/','',strtoupper($mac));
if($this->is_valid = preg_match('/^(\w{2})(\w{2})(\w{2})(\w{2})(\w{2})(\w{2})$/',$mac,$parts)){
array_shift($parts); //lose the first bit
$this->mac = implode(':',$parts);
}
}
}

//test
$mac_list = array("00-aa-11-bb-22-cc","00:aa:11:bb:22:cc","zz:00:11:22:ff:xx","00 aa 11 bb 22 cc");

foreach($mac_list as $mac){
$mactest = new mac($mac);
echo "In:$mac";
if($mactest->is_valid){
echo " valid $mactest->mac\n";
}else{
echo " NOT valid\n";
}
}
