這篇文章主要介紹了PHP使用SMTP郵件服務(wù)器發(fā)送郵件,結(jié)合實(shí)例形式分析了php基于SMTP協(xié)議的郵件發(fā)送類email.class.php定義與使用技巧,需要的朋友可以參考下
本文實(shí)例講述了PHP使用SMTP郵件服務(wù)器發(fā)送郵件。分享給大家供大家參考，具體如下：
用之前記得先去163注冊(cè)一個(gè)郵箱，然后打開SMTP服務(wù)，當(dāng)然也可以使用QQ郵箱等，但配置信息得改。
如圖所示，開啟QQ郵箱SMTP服務(wù)：
話不多說，直接上代碼
email.class.php 定義發(fā)送郵件的庫
