PHP 简易 E-Mail
通过 PHP 发送电子邮件的最简单的方式是发送一封文本 email。
在下面的例子中，我们首先声明变量($to, $subject, $message, $from, $headers)，然后我们在 mail() 函数中使用这些变量来发送了一封 e-mail：
<?<span>php </span><span>//</span><span> 何问起 hovertree.com</span> <span>$to</span> = "hello@hovertree.net"<span>; </span><span>$subject</span> = "Test mail"<span>; </span><span>$message</span> = "Hello! This is a simple email message."<span>; </span><span>$from</span> = "hello@hovertree.net"<span>; </span><span>$headers</span> = "From: <span>$from</span>"<span>; </span><span>mail</span>(<span>$to</span>,<span>$subject</span>,<span>$message</span>,<span>$headers</span><span>); </span><span>echo</span> "Mail Sent."<span>; </span>?>
PHP Mail Form
通过 PHP，您能够在自己的站点制作一个反馈表单。下面的例子向指定的 e-mail 地址发送了一条文本消息：
<html>
<body>
<!-- 何问起 hovertree.com -->
<?<span>php
</span><span>if</span> (<span>isset</span>(<span>$_REQUEST</span>['email'<span>]))
</span><span>//</span><span>if "email" is filled out, send email</span>
<span> {
</span><span>//</span><span>send email</span>
<span>$email</span> = <span>$_REQUEST</span>['email'<span>] ;
</span><span>$subject</span> = <span>$_REQUEST</span>['subject'<span>] ;
</span><span>$message</span> = <span>$_REQUEST</span>['message'<span>] ;
</span><span>mail</span>( "someone@example.com", "Subject: <span>$subject</span>",
<span>$message</span>, "From: <span>$email</span>"<span> );
</span><span>echo</span> "Thank you for using our mail form"<span>;
}
</span><span>else</span>
<span>//</span><span>if "email" is not filled out, display the form</span>
<span> {
</span><span>echo</span> "<span><form method='post' action='mailform.php'>
Email: <input name='email' type='text' /><br />
Subject: <input name='subject' type='text' /><br />
Message:<br />
<textarea name='message' rows='15' cols='40'>
</textarea><br />
<input type='submit' />
</form></span>"<span>;
}
</span>?>
</body>
</html>
例子解释：
1）windows需要配置IIS的SMTP；linux自带sendmail组件，无需设置，直接支持mail函数发送功能
2）php.ini中声明SMTP各项参数
3）mail("接收地址","邮件主题","邮件内容")函数的使用
例1：配置本地SMTP服务器
第一步： php.ini的设置:
SMTP = localhost
smtp_port = 25
sendmail_from=你的设定值
第二步：需要安装IIS自带的SMTP，在SMTP虚拟服务器上点击右键，在弹出的属性窗口里进行如下设置：
点击“访问”选项卡，再点击“中继”，在弹出的窗口出点击“添加”，然后选“单台计算机”，添加IP地址为“127.0.0.1”，然后一
路确定返回。
第三步：
mail("123456@qq.com","Test mail function of PHP.","hello world! hovertree.com");
?>
