详解使用php-imap查询操作邮件收件箱

确定实现方式

读取邮件的协议有POP3和IMAP两种，区别：POP3协议允许电子邮件客户端下载服务器上的邮件，但是在客户端的操作，不会反馈到服务器上。IMAP提供webmail与电子邮件客户端之间的双向通信，客户端的操作都会反馈到服务器上，对邮件进行的操作，服务器上的邮件也会做相应的动作。

需求要求处理完用户的邮件以后，将邮件标记为已处理，因此选用IMAP协议。

安装依赖

本地、服务器php均需要安装imap扩展。在项目的composer.json中添加php-imap(https://github.com/barbushin/php-imap)扩展如下：

"require": {   "php-imap/php-imap": "^3.1", },

配置相关服务

namespace applibraryservicemail;  use PhpImapExceptionsConnectionException; use PhpImapMailbox;  /**  * 收邮件服务邮件API接口  * Class PlayService  * @package applibraryservice  */ class ImapService {     public $path = '{imap.263.net:993/imap/ssl}INBOX';   // IMAP server and mailbox folder     public $login = 'user@263.cn';         // Username for the before configured mailbox     public $password = 'pwd';                   // Password for the before configured username     public $dir = null;        // Directory, where attachments will be saved (optional)     public $encoding = 'UTF-8';   // Server encoding (optional)      public $mailbox;      public function __construct()     {         $this->mailbox = new Mailbox(             $this->path,             $this->login,             $this->password,             $this->dir,             $this->encoding         );     }

获取所有未读邮件列表

public function unSeenList() {     try {         $mail_ids = $this->mailbox->searchMailbox('UNSEEN');     } catch (ConnectionException $ex) {         die('IMAP connection failed: ' . $ex->getMessage());     } catch (Exception $ex) {         die('An error occured: ' . $ex->getMessage());     }      // If $mailsIds is empty, no emails could be found     if (!$mail_ids) {         die('Mailbox is empty');     }      try {         $info = $this->mailbox->getMailsInfo($mail_ids);     } catch (ConnectionException $ex) {         echo "IMAP connection failed: " . $ex;         die();     }     return ['ids' => $mail_ids, 'list' => $info]; }

将某些邮件标记为已读

/**  * @param array $mail_ids  * @return mixed  */ public function markRead($mail_ids) {     return $this->mailbox->markMailsAsRead($mail_ids); }

搜索指定主题的邮件并标记为已读

$imap = new ImapService(); $condition = 'UNSEEN  SUBJECT "' . $title . '" SINCE "' . date('Y-m-d', strtotime('-1 days')) . '" FROM ' . $mail; $data['mail'] = $imap->mailbox->searchMailbox($condition); if (!empty($data['mail'])) {     $data['info'] = $imap->mailbox->getMailsInfo($data['mail']);     if ($params['mark'] == 1) {         $data['mark'] = $imap->markRead(array_column($data['info'], 'uid'));     } }
