原理:
第一:申请大量的邮箱帐号 腾讯的 126的 163的 新浪的 雅虎的 谷歌的 等等提供smtp服务的
第二:收集你要发送邮件的邮件列表
第三:遍历邮件列表,每一个邮件发送邮件
第四:用linux下定时脚本后台运行 我跑了两天 哈哈 ,因为为了尽可能的保证每一个都发送成功
原理是很简单,但是其中还是遇到很多的问题。
第一:邮件失败的问题,我这里采用两个方式解决,第一把大量的那些邮箱帐号依次去发送,直到成功。然后每次发送500封邮件 后把发送邮箱列表随机打散(避免一个持续失败)。
我用的是phpmailer
多的不多说了上代码了。phpmailer 大家自己搜索下载吧
入口脚本:就是linux 执行的 mail_001.php
<?php define('ROOT_PATH',dirname(__FILE__)); require_once 'library/senderApi.php'; //发送邮件接口 require_once 'config/senderListConf.php'; //发送邮件帐号列表 //读取文本 邮件地址 shuffle($senderListConf); $filename = "data/email.txt"; $fp = fopen($filename,"r"); $contents = fread($fp,filesize($filename)); $list_email=explode("\r\n",$contents); $len=count($list_email); fclose($fp); //邮件内容为网页上的内容 $htmlContent = file_get_contents('http://taobao.1080www.com'); // 参数说明(发送到, 邮件主题, 邮件内容, 附加信息, 用户名) foreach($list_email as $key=>$value) { $value = trim($value); $rs=explode("@",$value); $user_name = $rs['0']; smtp_mail($value, '秋季补水化妆品_秋季护肤皮肤保养_秋天皮肤干燥怎么办-小常识',$htmlContent, 'http://taobao.1080www.com/', $user_name,$senderListConf,0); sleep(3); if($key%200 == 0 && $key>0) { shuffle($senderListConf); //每200次 吧发送邮件顺序打乱一次 } } die('SendingOver.................'."\r\n"); ?>
封装phpmailer senderApi.php
<?php // 请求 PHPmailer类 文件 error_reporting(E_ERROR); require_once("phpmailer/phpmailer.class.php"); // 写入发送结果函数 function info_write($filename,$info_log) { $info.= $info_log; $info.="\r\n"; $fp = fopen ($filename,'a'); fwrite($fp,$info); fclose($fp); } //发送Email函数 function smtp_mail ( $sendto_email, $subject, $body, $extra_hdrs, $user_name,$senderListConf,$sender=0) { $batch_no = date("Y_m_d_H"); $mail = new PHPMailer(); $mail->IsSMTP(); $sender_info = $senderListConf[$sender]; if(!$sender_info) 'die 发送帐号出错了..............'; // send via SMTP $mail->Host = $sender_info['Host']; // SMTP servers $mail->SMTPAuth = true; // turn on SMTP authentication $mail->Username = $sender_info['Username']; // SMTP username 注意:普通邮件认证不需要加 @域名 $mail->Password = $sender_info['Password']; // SMTP password $mail->From = $sender_info['Username']; // 发件人邮箱 $mail->FromName = "淘宝推荐---TaoBao"; // 发件人 ,比如 中国资金管理网 $mail->CharSet = "UTF-8"; // 这里指定字符集! $mail->Encoding = "base64"; $mail->AddAddress($sendto_email,$user_name); // 收件人邮箱和姓名 $mail->AddReplyTo("ken@cscsws.com","淘宝推荐"); //$mail->WordWrap = 50; // set word wrap //$mail->AddAttachment("/var/tmp/file.tar.gz"); // attachment 附件1 //$mail->AddAttachment("/home/www/images/zhuanti/qiujibushui/qiujibushui_attache.jpg", "new.jpg"); //附件2 $mail->IsHTML(true); // send as HTML $mail->Subject = $subject; // 邮件内容 可以直接发送html文件 $mail->Body = $body; $mail->AltBody ="text/html"; if($mail->Send()) { info_write(ROOT_PATH.'/log/'.$batch_no."ok.txt","$user_name 发送成功"); } else { info_write(ROOT_PATH.'/log/'.$batch_no."falied.txt","$user_name 失败,发送账号".$sender_info['Username'].",错误信息$mail->ErrorInfo"); if($senderListConf[$sender+1]) { $sender = smtp_mail ( $sendto_email, $subject, $body, $extra_hdrs, $user_name,$senderListConf,($sender+1)); } } return $sender; }
发送邮件列表示例 senderListConf.php
<?php $senderListConf = array( //搜狐邮箱 array('Host'=>'smtp.sohu.com','Username'=>'youemail@sohu.com','Password'=>'yourpassword'), //雅虎邮箱 array('Host'=>'smtp.mail.yahoo.com','Username'=>'youemail@yahoo.cn','Password'=>'yourpassword'), //163邮箱 array('Host'=>'smtp.163.com','Username'=>'youemail@163.com','Password'=>'yourpassword'), //126邮箱 array('Host'=>'smtp.126.com','Username'=>'youemail@126.com','Password'=>'yourpassword'), //qq邮箱 array('Host'=>'smtp.qq.com','Username'=>'youemail@qq.com','Password'=>'yourpassword'), //谷歌邮箱 array('Host'=>'smtp.gmail.com','Username'=>'youemail@gmail.com','Password'=>'yourpassword'), //139邮箱 array('Host'=>'smtp.139.com','Username'=>'youemail@139.com','Password'=>'yourpassword'), //qq邮箱 array('Host'=>'smtp.qq.com','Username'=>'youemail@qq.com','Password'=>'(yourpassword'), );

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
