发送电子邮件在localhost和cpanel中不起作用

Question

如何修改有关发送电子邮件的脚本contact.php。 已经尝试cpanel但不工作

<?php if ($_SERVER['REQUEST_METHOD'] == 'POST') {
if(!empty($_POST['contact_name']) && !empty($_POST['contact_email']) && !empty($_POST['contact_message'])) {
    $to = 'klokolev@gmail.com'; // Replace with your email.
    $body = "Name: {$_POST['contact_name']}\n\nEmail: {$_POST['contact_email']}\n\nMessage: {$_POST['contact_message']}";
    mail($to, "Contact Form Submission", $body, "From: {$_POST['contact_email']}");
}}?>
