imap_search限制返回的消息数 [英] imap_search limit the number of messages returned

问题描述

我有PHP脚本，可以从邮箱中获取消息.我使用imap_search函数: $ emails = imap_search($ mbox，'UNSEEN');

I have PHP script that fetch messages from a mailbox. I use the imap_search function: $emails = imap_search($mbox, 'UNSEEN');

是否有一种方法来限制返回的消息数.现在，在巨大的邮箱上，我收到5000条消息.我只希望按日期排序的前20名.

Is there a way to limit the number of returned messages. Right now on huge mailboxes i get like 5000 messages. I want only the top 20 ordered by date.

有办法吗?

谢谢.
