我们在进行网站开发的是，通常都会需要进行发送邮件的功能，那么如何实现这一功能呢？这时候就用到了PHP语言。下面就介绍一下
在一些网站注册过会员之后，系统会自动发送一封注册信息邮件或者激活码之类的到自己的邮箱里，不但保证了邮箱的真实性，而且还可以使用户有一份备忘信息，那么怎样实现呢？如果你能够熟练运用PHP发送邮件，那就不用往下看了，这篇文章向你推荐一个优秀的mail类：PHPMailer，遗憾的是优秀的程序往往出自老外之手，管他呢，网络无国界，先给大家一个简单的演示吧：
PHP发送邮件的页面代码：
<ol class="dp-xml">
<li class="alt"><span><span class="tag"><span> ?php </span></span></span></li>
<li><span>require("mail/class.phpmailer.php");//调用 </span></li>
<li class="alt">
<span>$</span><span class="attribute">mail</span><span> = </span><span class="attribute-value">new</span><span> PHPMailer();//实例化phpmailer </span>
</li>
<li>
<span>$</span><span class="attribute">address</span><span> = </span><span class="attribute-value">"mailxi@126.com"</span><span>;//接收邮件的邮箱 </span>
</li>
<li class="alt">
<span>$mail-</span><span class="tag">></span><span>IsSMTP(); // 设置发送邮件的协议：SMTP </span>
</li>
<li>
<span>$mail-</span><span class="tag">></span><span class="attribute">Host</span><span> = </span><span class="attribute-value">"smtp.163.com"</span><span>; // 发送邮件的服务器 </span>
</li>
<li class="alt">
<span>$mail-</span><span class="tag">></span><span class="attribute">SMTPAuth</span><span> = </span><span class="attribute-value">true</span><span>; // 打开SMTP </span>
</li>
<li>
<span>$mail-</span><span class="tag">></span><span class="attribute">Username</span><span> = </span><span class="attribute-value">"我的账户"</span><span>; // SMTP账户 </span>
</li>
<li class="alt">
<span>$mail-</span><span class="tag">></span><span class="attribute">Password</span><span> = </span><span class="attribute-value">"我的密码"</span><span>; // SMTP密码 </span>
</li>
<li>
<span>$mail-</span><span class="tag">></span><span class="attribute">From</span><span> = </span><span class="attribute-value">"mailxi@163.com"</span><span>; </span>
</li>
<li class="alt">
<span>$mail-</span><span class="tag">></span><span class="attribute">FromName</span><span> = </span><span class="attribute-value">"peng"</span><span>; </span>
</li>
<li>
<span>$mail-</span><span class="tag">></span><span>AddAddress("$address", ""); </span>
</li>
<li class="alt">
<span>//$mail-</span><span class="tag">></span><span>AddAddress(""); // name is optional </span>
</li>
<li>
<span>//$mail-</span><span class="tag">></span><span>AddReplyTo("", ""); </span>
</li>
<li class="alt">
<span>//$mail-</span><span class="tag">></span><span class="attribute">WordWrap</span><span> = </span><span class="attribute-value">50</span><span>; // set word wrap to 50 characters </span>
</li>
<li>
<span>//$mail-</span><span class="tag">></span><span>AddAttachment("/var/tmp/file.tar.gz"); // add attachments </span>
</li>
<li class="alt">
<span>//$mail-</span><span class="tag">></span><span>AddAttachment("/tmp/image.jpg", "new.jpg"); // optional name </span>
</li>
<li>
<span>//$mail-</span><span class="tag">></span><span>IsHTML(true); // set email format to HTML </span>
</li>
<li class="alt">
<span>$mail-</span><span class="tag">></span><span class="attribute">CharSet</span><span> = </span><span class="attribute-value">"UTF-8"</span><span>;//设置字符集编码 </span>
</li>
<li>
<span>$mail-</span><span class="tag">></span><span class="attribute">Subject</span><span> = </span><span class="attribute-value">"Sinopf的测试邮件"</span><span>; </span>
</li>
<li class="alt">
<span>$mail-</span><span class="tag">></span><span class="attribute">Body</span><span> = </span><span class="attribute-value">"Hello,Sinopf的测试邮件"</span><span>;//邮件内容（可以是HTML邮件） </span>
</li>
<li>
<span>$mail-</span><span class="tag">></span><span class="attribute">AltBody</span><span> = </span><span class="attribute-value">"This is the body in plain text for non-HTML mail clients"</span><span>; </span>
</li>
<li class="alt">
<span>if(!$mail-</span><span class="tag">></span><span>Send()) </span>
</li>
<li><span>{ </span></li>
<li class="alt">
<span>echo "Message could not be sent. </span><span class="tag"><span> </span><span class="tag-name">p</span><span class="tag">></span><span>"; </span></span>
</li>
<li>
<span>echo "Mailer Error: " . $mail-</span><span class="tag">></span><span>ErrorInfo; </span>
</li>
<li class="alt"><span>exit; </span></li>
<li><span>} </span></li>
<li class="alt"><span>echo "Message has been sent";//发送成功显示的信息 </span></li>
<li>
<span class="tag">?></span><span> </span>
</li>
</ol>怎么样？PHP发送邮件的实现方法简单吧？当然这只是一个简单的演示，更多应用还需要你自己捉摸，比如实现发送激活码，发送注册信息之类的，举一反三。
