array filter

[DougBTX]

This function works, but feels a little messy. Is it good PHP(5)? I feel like there should be a better solution.

function filter_array($request, $filter) {
    foreach ($request as $key => $value) {
        if (in_array($key, $filter)) {
            $result[$key] = $value;
        }
    }
    return $result;
}

$request = array('alpha' => 'est', 'beta' => 'meh', 'gamma' => 'oui');
$filter  = array('alpha', 'beta');

$filtered = filter_array($request, $filter);

// output I want:
// $filtered == array('alpha' => 'est', 'beta' => 'meh'); 

Thanks,
Douglas
