Question

我正在做一个表单验证器（以及其他内容）并且我已经在我的脚本中设置了响应代码，因此我可以使用AJAX ..出于某些奇怪的原因，它会在发生此错误时抛出此错误我执行脚本：

致命错误：调用未定义的函数http_response_code（）

我的剧本：

if ($_SERVER["REQUEST_METHOD"] == "POST"){
    $email = filter_var(trim($_POST['email'],FILTER_SANITIZE_EMAIL));
    $code = trim($_POST['code']);

    if (!filter_var($email, FILTER_VALIDATE_EMAIL) OR empty($code)){
        http_response_code(400);
        echo "Oops! There was a problem with your submission. Try again!";
        exit;
    }

    if(!$conn) die("Something wrong happened" . mysql_error());

    if(mysql_query($sql,$conn)){

        if(isset($_POST['newsletter'])){
            $MailChimp = new MailChimp();
            $list_id = '*********';
            $user_info = array('email_address' => $email,'status' => 'subscribed');
            $result = $MailChimp->post("lists/$list_id/members",$user_info);

            if(strpos($MailChimp->getLastError(), 'is already a list member') !== false) echo 'You are already subscribed, smarty pants!';
        }

        http_response_code(200);
        echo "Thank you!";
    }

    else{
       http_response_code(500);
       echo "Oops! Something went wrong";
    }

       if(!mysql_query($sql,$conn)) echo "<p>" . "There seems to be a problem :< ... Please check the info you provided and try again!" . "</p>";
       else echo "<p>" . "Much thanks! Very wow :D" . "</p>";
       mysql_close($conn);
}

任何人都知道可能发生的事情或更好的方法吗？

使用http_response_code获取未定义的函数
