I would merge 2 arrays but keep the values unique in the result array.
I hope this will help...
<?php
function array_merge_recursive_unique($array1, $array2) {
foreach($array2 AS $k => $v) {
if(!isset($array1[$k]))
{
$array1[$k] = $v;
}
else
{
if(!is_array($v)){
if(is_array($array1[$k]))
{
if(!in_array($v,$array1[$k]))
{
$array1[$k][] = $v;
}
}
else
{
if($array1[$k] != $v)
$array1[$k] = array($array1[$k], $v);
}
}
else
{
$array1[$k] = array_merge_recursive_unique($array1,$array2[$k]);
}
}
}
unset($k, $v);
return $array1;
}
?>
