php发邮件foxmail标题显示乱码问题解决方案

简介: 之前在大神那里找了一个SMTP发送邮件的源码,应用之后是可以发送邮件了,然后web查看邮件也正常,但是foxmail客户端一直显示标题乱码,正文是正常的,几经搜索之后,终于发现原来邮件是base64编码的,所有需要将标题经过编码之后才发送,测试之后,果然正常了。

之前在大神那里找了一个SMTP发送邮件的源码,应用之后是可以发送邮件了,然后web查看邮件也正常,但是foxmail客户端一直显示标题乱码,正文是正常的,几经搜索之后,终于发现原来邮件是base64编码的,所有需要将标题经过编码之后才发送,测试之后,果然正常了。

$mailsubject = "=?UTF-8?B?".base64_encode($mailsubject)."?=";    //标题转码,防止foxmail客户端乱码

详细代码如下,mail.php是借用大神的,但是忘记在哪下载了的,如需要下线,请联系。

$smtp->debug = false;                     //是否显示发送的调试信息 
?>

将发送独立出来是方便修改参数,如需修改邮件主题等,可以将变量增加到send.php里面即可

send.php

<?php
include 'mail.php';
$content = '中文标题test';
$smtpemailto = 'm@huangwx.cn';
$mailbody = "<h1>{$content}</h1><br /><h2>Powered by <a href='http://www.huangwx.cn'>微凉</a><h2>";      //邮件内容
$smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
?>
