php邮件主题未发送 - php mail subject not send

php mail subject not send

本文关键字：php | 更新日期: 2023-09-27

我正在尝试用php发送电子邮件，它运行良好，但只有我收到的消息有问题，主题不起作用。有人能找到问题吗？

  <?php
        $to = "me@email.com";
        $name = $_REQUEST['name'];
        $headers = "From: $from";
        $subject = "You have a message from $name.";
        $fields = array();
        $fields{"email"} = "email";
        $fields{"message"} = "message";
        $body = "Message:'n'n"; foreach($fields as $a => $b){   $body .= sprintf("%20s: %s'n",$b,$_REQUEST[$a]); }
        $send = mail($to, $body, $headers, $subject);
    ?>

尝试按如下方式更改$send顺序；

 $send = mail($to, $subject, $body, $headers);

更新：感谢David的指出，将变量$from添加到您的php中，这样发件人的电子邮件也将包含在$headers中：

<?php
        $to = "me@email.com";
        $from = $_REQUEST['from'];
        $name = $_REQUEST['name'];
        $headers = "From: $from";
        $subject = "You have a message from $name.";
        $fields = array();
        $fields{"email"} = "email";
        $fields{"message"} = "message";
        $body = "Message:'n'n"; foreach($fields as $a => $b){   $body .= sprintf("%20s: %s'n",$b,$_REQUEST[$a]); }
        $send = mail($to, $subject, $body, $headers);
    ?>
