用程序生成好一个邮件标题和内容，之后想要完美的在收件箱里接收，需要编写针对于邮件的html。
美观可以放在第二位，但是需要让邮箱认出是html来，否则内容会以原码显示。
在邮件headers中加入正确的Content-type和charset即可。
email html中的布局基本是用table，css样式尽量直接写在html标签里，以下分别是用原生php和php-mail(SMTP)来发邮件。
<?php $message=' <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>title</title> </head> <body> <table> <tr> <th>three days forcast</th> </tr> </table> </body> </html>'; $to = '[email protected]'; $subject =send mail using php; $from = "[email protected]"; $headers = "From: $from\n"; $headers .= "Reply-To: $from\n"; $headers .= "MIME-Version: 1.0\n"; $headers .= "Content-type: text/html; charset=iso-8859-1"; mail($to, $subject, $message,$headers); echo "Mail Sent."; ?>
使用pear mail(SMTP)发送邮件
<?php
//require apt-get install php-mail, reference: http://php.net/manual/en/function.mail.php
include("Mail.php");
$message='
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>title</title>
</head>
<body>
<table>
<tr>
<th>three days forcast</th>
</tr>
</table>
</body>
</html>';
$to = '[email protected]';
$subject =send mail using php;
$headers["From"] = "[email protected]";
$headers["TO"] = "[email protected]";
$headers["Subject"] = "$subject";
$headers["MIME-Version"] = "1.0";
$headers["Content-type"] = "text/html";
$headers["charset"] = "iso-8859-1";
$params["host"] = "smtp.163.com";
$params["port"] = "25";
$params["auth"] = true;
$params["username"] = "[email protected]";
$params["password"] = "yourpassword";
$mail_object = & Mail::factory("smtp", $params);
$mail_object->send($to, $headers, $message);
//echo $message;
echo "Mail Sent.";
?>
