Filter array based on second array

Question

I have an array $data and it is required to be filtered based on another array $clr. I have done it by foreach and solved my purpose but I am looking for an optimum way like map or filter. What I have tried is:

$clr = [1, 2, 4, 6, 8, 13, 21];
$data = [2, 3, 8];

foreach($clr as $val)
{
    if(($key = array_search($val, $data)) !== false) unset($data[$key]);
}

print '<pre>';
print_r($data);

Any of your suggestion will be appreciated.

@SahilGulati should be `$data = array_diff($data,$clr);` you got the parameter order wrong — bansi, May 08 '17 at 09:52
you can use array_filter as well. have a look at https://3v4l.org/i53Ma — Chetan Ameta, May 08 '17 at 09:57

You can use array_diff($data, $clr); live demo.

I think `$data` should be first argument. – u_mulder May 08 '17 at 09:50
