php 发送邮件
php我们可以使用系统的mail函数去发送邮件 但是需要配置一下邮件环境 这里选择使用PHPMailer 这样比较方便
首先下载PHPMailer:https://github.com/Synchro/PHPMailer
然后将下载好的文件夹解压放到根目录下即可
然后调用mail函数发送邮件:
比如:
<?php$to = "542633273@qq.com";$subject = "Test mail";$message = "Hello! This is a dsdsimple email message.";$from = "542633273@qq.com";$headers = "From: $from";mail($to,$subject,$message,$headers);echo "Mail Sent.";?>
--------------------------更新:上面的方法虽然简单方便,但是有个问题就是不稳地,有时候发送到垃圾邮箱里,有时候收不到邮件,所以不太实用.---------------------------
以下方法,主要是使用了一个障眼法,即发件人邮箱与收件人邮箱都是自己设定的,而真正的发件人邮箱是以内容的形式发送过去的,即用户在填写内容和自己邮箱信息后点击发送按钮,后台真正是通过我自己好邮箱A发送到我自己的邮箱B的 只不过用户真正有邮箱会通过内容的形式反映出来.这样做可以保证邮件的稳定性以及不会被当做垃圾邮件处理
/** * 注：本邮件类都是经过我测试成功了的，如果大家发送邮件的时候遇到了失败的问题，请从以下几点排查： * 1. 用户名和密码是否正确； * 2. 检查邮箱设置是否启用了smtp服务； * 3. 是否是php环境的问题导致； * 4. $smtp->debug = false改为true，可以显示错误信息，然后可以复制报错信息到网上搜一下错误的原因； * 5. 如果还是不能解决，可以访问：http://www.daixiaorui.com/read/16.html#viewpl * 下面的评论中，可能有你要找的答案。 */ require_once "email.class.php"; //******************** 配置信息 ******************************** $smtpserver = "smtp.126.com";//SMTP服务器 $smtpserverport =25;//SMTP服务器端口 $smtpusermail = "nnnnnnn@126.com";//发件人邮箱 $smtpemailto = "mmmmmmm@126.com";//发送给谁 $smtpuser = "nnnnnnn@126.com";//SMTP服务器的用户帐号 $smtppass = "nnnnnnn";//SMTP服务器的用户密码 $mailtitle = $subject ;//邮件主题 $mailcontent = "<h3>".$message."</h3>"."<br/>"."<h5>发件人邮箱:"."$email"."<br/><br/><br/>"."发件人昵称:"."$name"."</h5>";//邮件内容 $mailtype = "HTML";//邮件格式（HTML/TXT）,TXT为文本邮件 //************************ 配置信息 **************************** $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//这里面的一个true是表示使用身份验证,否则不使用身份验证. $smtp->debug = false;//是否显示发送的调试信息 $state = $smtp->sendmail($smtpemailto, $smtpusermail, $mailtitle, $mailcontent, $mailtype); if($state==""){ echo"<br/><br/><br/><br/><br/><br/><br/><br/><br/>"; echo "<center><h1>邮件发送失败</h1></center>"; echo "<center><h3>请检查邮箱是否正确!</h3></center>"; echo "<center><h5><a href=http://www.mamicode.com/‘../index.html‘>马上返回"; exit(); }else{ echo"<br/><br/><br/><br/><br/><br/><br/><br/><br/>"; echo "<center><h1>$name,已收到您的来信</h1></center>"; echo "<center><h3>我会尽快回复的</h3></center>"; echo "<center><h5><a href=http://www.mamicode.com/‘../index.html‘>马上返回"; }
