【问题讨论】：

“500 内部服务器错误”状态码（或空白页）表示您的脚本正在抛出错误，但您尚未配置 PHP 以显示错误消息。这是您在更进一步之前需要解决的问题；如果没有错误消息的帮助，就不可能正确编码。这是brief explanation。
我建议你查看 apache 日志，在那里你可以得到确切的错误
感谢您的及时回复...您的意思是我添加代码以显示错误...我无权访问 php.ini 或 htaccess 文件。有没有其他办法？
$user = "$output3"; ... 是正确的？我觉得应该是 $user = $output3;
ofcorse ，如果你放 "" 那么这个东西会变成字符串

标签： php email phpmailer internal-server-error

【解决方案1】：

change $user = "$output3"; to $user = $output3;

【讨论】：

$result3 和 $output3 无论如何都应该是一个字符串（电子邮件地址），所以不会造成任何伤害（只是浪费了几个周期）。

【解决方案2】：

如果您的 php 代码有致命错误但错误显示已关闭，则会显示 500 Internal Server Error。你可以试试这个来查看错误本身而不是 500 错误页面：

在你的 php 文件中：

ini_set('display_errors', 1);

如果您有权访问 Apache 错误日志，您还可以查看它们。

【讨论】：

【解决方案3】：

如果您删除/注释掉第二个 mail() 调用，它会起作用吗？您确实知道您可以放置多个“收件人”地址并只使用一个 mail()，不是吗？

$mail_to  = ' myemailid@email.com, '.$user;

我不确定前导空格是否会造成任何伤害（如果没有其他方法，请尝试将其删除）。现在，$user 是合法的电子邮件地址吗？你打印出来检查了吗？

或者，您可以在标题中添加一个“抄送：”电子邮件地址，如果您希望以这种方式将其发送给该人。
