如何使用 PHP 从网站发送电子邮件？

Question

我开发了一个网站，想从该网站域发送邮件 我已经配置了邮件功能，然后它运行良好，但几个月后它在这里不起作用是我的代码

$email_from = 'xxx@domainname.lk';//<== update the email address
$email_subject = "New Visitor";
$email_body = "new visitor".

$to = 'qqq@gmail.com';//<== update the email address
$headers .= "From: $email_from \r\n";

//Send the email!
mail($to,$email_subject,$email_body,$headers);
//done. redirect to thank-you page.
header('Location: thank-you.html');

Answer 1

我认为 $email_body 变量的值应该以分号 (;) 结尾，并且 $headers 应该像下面这样写

$headers = 'From: webmaster@example.com' . "\r\n" .
      'Reply-To: webmaster@example.com' . "\r\n" .
      'X-Mailer: PHP/' . phpversion();
