詳解使用php-imap查詢操作郵件收件箱

確定實現方式

讀取郵件的協議有POP3和IMAP兩種，區別：POP3協議允許電子郵件客戶端下載服務器上的郵件，但是在客戶端的操作，不會反饋到服務器上。IMAP提供webmail與電子郵件客戶端之間的雙向通信，客戶端的操作都會反饋到服務器上，對郵件進行的操作，服務器上的郵件也會做相應的動作。

需求要求處理完用戶的郵件以后，將郵件標記為已處理，因此選用IMAP協議。

安裝依賴

本地、服務器php均需要安裝imap擴展。在項目的composer.json中添加php-imap(https://github.com/barbushin/php-imap)擴展如下：

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

配置相關服務

namespace applibraryservicemail;  use PhpImapExceptionsConnectionException; use PhpImapMailbox;  /**  * 收郵件服務郵件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         );     }

獲取所有未讀郵件列表

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]; }

將某些郵件標記為已讀

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

搜索指定主題的郵件并標記為已讀

$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'));     } }
