In the following example, we first declare the variables ($to, $subject, $message, $from, $headers), and then we use these variables in the mail() function to send an E -mail:

The code is as follows:

<?php
$to = "someone@example.com";         // 邮件接收者
$subject = "参数邮件";                // 邮件标题
$message = "Hello! 这是邮件的内容。";  // 邮件正文
$from = "someonelse@example.com";   // 邮件发送者
$headers = "From:" . $from;         // 头部信息设置
mail($to,$subject,$message,$headers);
echo "邮件已发送";
?>
