用phpmail發送郵件，簡單實現php發郵件功能！
不少網站都開始有郵箱驗證碼驗證了。
例如網站評論有人回覆了，你就能立馬收到郵件。
這些功能是如何實現的呢？
其實就是用php實現的，固然這樣的類不少，我這裏給你們分享的是phpmailphp
首先該文件有一個封裝類和一個配置html
很簡單，而後一個表單進行發郵件。服務器
發件人是個人163郵箱
收件人是個人QQ郵箱php7
當我點擊發送的時候，我就會在個人163郵箱的「已發送」列表看到一篇發送的郵件dom
而後登錄QQ郵箱就能夠看到收件箱有一封剛剛發過來的郵件。
若是收件箱看不到，請到垃圾箱找找......個人是在垃圾箱找到的。post
這就是整個發送過程！學習

echo "<a href='index.html'>點此返回</a>";
exit();
}
echo "恭喜！郵件發送成功！！";
echo "<a href='index.html'>點此返回</a>";
echo "</div>";
?>
注意：$smtppass這裏不是填郵箱的密碼，填密碼是不行的，要在163後臺設置打開受權開關設置一個受權碼，打開全部的服務便可。
通常發件人和收件人都在同一個網域就不會被拉入黑名單！發件人用騰訊的，收件人也用騰訊的，那就絕對沒問題。
