无法让代码在 PHP 5.5.9 中工作

Question

此代码在 PHP 5.3 中运行良好，但我不知道如何才能使其在 LAMP 服务器上的 PHP 5.5.9 中运行。我尝试四处搜索，但没有找到任何解决方案。有什么解决办法吗？

所以；用户正确地看到了发件人，而事实上它总是说邮件已发送，甚至在他们点击提交按钮之前也是如此。第二，它最后应该发的邮件，发不出去，什么都没有。

问题是在 5.5.9 上它不发送信息邮件（给我）并且用户在他们点击 sumbit 按钮之前得到邮件发送的信息，即使它是错误的归档。

Answer 1

action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>" -> action=""
if (empty($Err["Err"])) { -> $Err 可能仍为“1”（无数组），这将引发警告
您可能在此处遇到 UTF-8 问题（我在 html 中没有看到 html 元标记/或 xml 通知或字符编码标记）

但请先告诉我们哪里出了问题！在代码开头开启显示errors/warnings：

ini_set('error_reporting', E_ALL); ini_set("display_errors", "1");

Answer 2

我的第一个猜测是，虽然您的 PHP 5.3 服务器配置为发送电子邮件，但您的 PHP 5.5.9 不是。简单测试 - 使用硬编码值调用 mail()。

even before they hit the submit button

我不确定你说的那一点是什么意思，但也许你在用 AJAX 做某事。查看浏览器的控制台日志以查看所有 HTTP 请求和响应。

Answer 3

在上次测试中 if (empty($Err["Err"])) { 应该是 if (empty($Err)) { 的问题。

问题已解决。
