尝试使用 mail() 从数据库表发送记录

Question

我正在使用 XAMPP，我想从数据库表中选择一个随机记录并通过电子邮件发送。我正在使用测试邮件服务器工具，但收到下一个错误：警告：mail()：第 24 行 C:\xampp\htdocs\dailyapp\sender2.php 中的错误消息返回路径 糟糕！出了点问题，我们无法发送您的消息。这里可能发生什么？任何想法？PHP代码：<?php$servername = "localhost";$username = "root";$password = "";$dbname = "dapp";// Create connection$conn = new mysqli($servername, $username, $password, $dbname);// Check connectionif ($conn->connect_error) {  die("Connection failed: " . $conn->connect_error);}$recipient = "[e-mail]";$sql = "SELECT * FROM my_messages ORDER BY RAND() LIMIT 1";$result = $conn->query($sql);if ($result->num_rows > 0) {    ($row = $result->fetch_assoc());    $subject = $row["subject"];    $message = $row["message"];        if (mail($recipient, $subject, $message)) {        http_response_code(200);        echo "All good";    }        else {        http_response_code(500);        echo "Oops! Something went wrong and we couldn't send your message.";        }}    else {    echo 0;};?>

Answer 1

像这样添加和标题

$header = array(

    'From' => '[e-mail]',

    'Reply-To' => '[e-mail]',

    'X-Mailer' => 'PHP/' . phpversion()

);

并输入您自己的信息

并在邮件功能中使用它

mail($recipient, $subject, $message,$header)
