学习如何将PHP与HTML结合起来完成简单动态页面 检查 POP3/SMTP 协定的时分想测验考试一下本人写一个操作类,中心没啥,就是利用 fsockopen ,然后写入/吸收数据,只完成了最中心的局部功效,看成是进修 Socket 操作的练手。个中参考了 RFC 2449和一个国外的复杂Web邮件体系 Uebimiau 的局部代码,不外相对没有抄他滴,HOHO,相对原创。假如你喜好,请保藏,随意修正,嗯,然而记得不要删除偶类里的申明,究竟偶也是辛辛劳苦写了好几天呐。
别的,接待自在发扬,改良或修改这个类,但愿可以为你所用。代码没有仔细细心的调试,发明bug请本人修改,HOHO!

刚开始因为习惯于ASP格式的写法,总是在这些方面出现问题,自己还总是找不到问题所在,这就提醒了自己,在写代码的时候一定要认真,不能粗心地老是少个“;”或者字母大小写不分,要不然很可能找半天都找不到错误。 |
