Answer 1

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

Answer 2

如果您的php代码有致命错误但关闭了错误显示，则会显示<500>内部服务器错误。您可以尝试这样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);

如果您有权访问它们，也可以检查Apache错误日志。

Answer 3

如果删除/注释掉第二个mail（）调用，它有效吗？你知道你可以把多个＆＃34;放到＆＃34;地址和只使用一个邮件（），不是吗？

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

我不确定领先的空间是否造成任何伤害（如果没有别的办法，请尝试删除它）。现在，$user是合法的电子邮件地址吗？你打印出来检查一下吗？

或者，您可以添加＆＃34; cc：＆＃34;标题中的电子邮件地址，如果您希望将其发送给此人。
