PHP 有效的 http 状态

Question

在我的网站上，用户可以在标准文本输入字段中输入 HTTP 状态代码。即 200、400、404、403 等...

有什么方法可以检查 HTTP 状态码是否有效。例如，如果用户输入“123”，它将返回 false。除了做一个大而丑陋的 if 或 switch 语句之外，我目前无法想到或找到其他方法。

Answer 1

根据w3.org以下 HTTP/1.1 状态码有效:

$status_code = array("100","101","200","201","202","203","204","205","206","300","301","302","303","304","305","306","307","400","401","402","403","404","405","406","407","408","409","410","411","412","413","414","415","416","417","500","501","502","503","504","505");

if(in_array("404", $status_code)){
    echo "valid";
  }else{
    echo "invalid";
  }
