提交表单

PHP simply implements sending emails and preventing them from being treated as spam

发送邮件处理

mail.php

<?php //获取表单提交的邮件标题
$title = $_POST["title"];
//获取表单提交的内容
$content = $_POST["content"];
include_once("smtp.class.php");
    $smtpserver = "smtp.163.com"; //SMTP服务器
    $smtpserverport = 25; //SMTP服务器端口
    //获取表单提交的邮件接收人邮箱号码
    $email = $_POST["email"];
    $smtpusermail = "你的163邮箱地址"; //SMTP服务器的用户邮箱
    $smtpuser = "你的163邮箱地址"; //SMTP服务器的用户帐号
    $smtppass = "授权密码"; //SMTP服务器的授权密码
    $smtp = new Smtp($smtpserver, $smtpserverport, true, $smtpuser, $smtppass); //这里面的一个true是表示使用身份验证,否则不使用身份验证.
    $emailtype = "HTML"; //信件类型，文本:text；网页：HTML
    $smtpemailto = $email;
    $smtpemailfrom = $smtpusermail;
    $emailsubject = $title;
    $emailbody = "<p>".$content."";
 
    //开始发送邮件
    $smtp->sendmail($smtpemailto, $smtpemailfrom, $emailsubject, $emailbody, $emailtype);
    echo "发送成功！";
?>

mail.php

里面只需设置你的163账号和授权密码即可

还有一个文件
smtp.class.php
这个不要动就行，拷贝到同一目录。

How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
