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";
?>

$subject = $_REQUEST[&#39;cars&#39;] ;
$message = $_REQUEST[&#39;message&#39;] ;
mail("someone@example.com", $cars,
$message, "From:" . $email);
echo "邮件发送成功";
} else { // 如果没有邮箱参数则显示表单
echo "<form method=&#39;post&#39; action=&#39;mailform.php&#39;>
Email: <input name=&#39;email&#39; type=&#39;text&#39;><br>
