You want to use preg_replace to replace all non-numeric chars with ”

$arr = array(
    1 => "1234 perr & *",
    2 => "3456 hsdsd 3434"
);

foreach($arr as &$item) {
    $item = preg_replace('/\D/', '', $item);
}

var_dump($arr);

results in

array(2) { [1]=> string(4) "1234" [2]=> &string(8) "34563434" }
