请尝试以下代码
function runMyFunction() {
echo 'I just ran a php function';
$to = 'myemailud@us.edu';
$subject = 'the subject';
$message = 'hello';
$headers = "Return-Path: myemailud@us.edu'r'n";
$headers .= "From: myemailud@us.edu'r'n";
$headers .= 'MIME-Version: 1.0'."'r'n";
mail($to, $subject, $message, $headers);
}
上面的代码在我的网站上正常工作。您是否在开发环境或托管服务器上进行测试。在开发机器的情况下，我非常怀疑您是否配置了SMTP邮件服务器。Linux 机器具有默认的 smtp 模块。
请提供测试服务器的更多详细信息，并可以帮助您使用一些命令来验证邮件服务器设置。
您正在收件箱中检查电子邮件，这是一个邮件客户端，每个人都要求您检查邮件服务器。
