This filters out a given number out from an array and returns the new length of the array

filterval.php

<?php
function filter_val( array $arr, int $val) : int{
    $output = array_filter($arr, function($value) use ($val) {
        return $value - $val != 0;  
      });

      return count($output);
}
$array = [5,2,2,5,3];
$val = 5;
print_r(filter_val($array, $val));

Well, Understood, I guess the type hinting doesn't help the average user much...

Thanks for the review, Really appreciate
