最近在业务场景里有接管解析用户被动发送的邮件，应用php-imap实现了这一需要，记录一下。
确定实现形式
读取邮件的协定有POP3和IMAP两种，区别：POP3协定容许电子邮件客户端下载服务器上的邮件，然而在客户端的操作，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。
需要要求解决完用户的邮件当前，将邮件标记为已解决，因而选用IMAP协定。
装置依赖
本地、服务器php均须要装置imap扩大。在我的项目的composer.json中增加php-imap扩大如下：
"require": { "php-imap/php-imap": "^3.1",},配置相干服务
namespace app\library\service\mail;use PhpImap\Exceptions\ConnectionException;use PhpImap\Mailbox;/** * 收邮件服务邮件API接口 * Class PlayService * @package app\library\service */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);}搜寻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')); }}
