function FindStartEnd($array, $val)
{
    $type = gettype($array);
    try {
        if (!$array) {
            throw new Exception("Expects parameter 1 to be array and should contain at least one value");
        }
        if (!is_numeric($val)) {
            throw new Exception("Second value passed must be a number");
        }
        if(sort($array)){
            $indexes = array_keys($array, $val);
            if (!$indexes) {
                return [-1, -1];
            }
            return [min($indexes), max($indexes)];
        }
        throw new Exception("expects parameter 1 to be array, $type given");
      
    } catch (Exception $e) {
        echo 'Error: ' . $e->getMessage() . "\n";
    }
}

print_r(FindStartEnd([0,8,-2,5,0], 0));

Thank you very much and look forward to coming Friday.
