not necessarily the best solution but something like the following works:-
<?php
$a = array(1,2,3,4,5,6);
$b = array(4,6,9);
$c = array();
$d = $a;
foreach ($b as $value)
{
if (in_array($value, $a))
{
$c[] = $value;
}
else
{
$d[] = $value;
}
}
print_r($c);
print_r($d);
?>
this of course assumes that there will be no duplicate entries in $a already

$C=array_intersect($A,$B)
