我想使用preg_match（）函数添加阿拉伯字符

Question

function validate_name($name, $name_limit, $name_system){
    if(preg_match("/^[a-zA-Z0-9]{1,}[_-]?[a-zA-Z0-9]{1,}[_-]?[a-zA-Z0-9]{1,}$/", $name) && strlen($name) <= $name_limit && !ctype_digit($name) && $name !== $name_system && strlen($name) >= 4){
        $valid_name = 1;
    }
    else {
        $valid_name = 0;
    }
    return $valid_name;
}
