PHP使用SwiftMailer发送邮件

用到了swiftmailer 的lib库

官方网址：http://swiftmailer.org/

require_once 'lib/swift_required.php';
//给我发送邮件
function mailer(){
    $body ="要发送的内容";
    $subject = "要发送主题"

$transport = Swift_SmtpTransport::newInstance('smtp.qq.com', 25);//设置发送 smtp 服务器和端口
    $transport->setUsername('发送邮箱 地址 ');
    $transport->setPassword('发送邮箱密码');
    $mailer = Swift_Mailer::newInstance($transport);
    $message = Swift_Message::newInstance();
    $message->setFrom(array( '发送邮箱地址'  =>'发送人'));
    $message->setTo(array('接受邮箱地址' => '接受人'));
    $message->setSubject($subject);
    $message->setBody($body, 'text/html', 'utf-8');
    //$message->attach(Swift_Attachment::fromPath('pic.jpg', 'image/jpeg')->setFilename('rename_pic.jpg'));//发送附件
    try{
        $mailer->send($message);
    }
    catch (Swift_ConnectionException $e){
        echo 'There was a problem communicating with SMTP: ' . $e->getMessage();
    }
}

Swift 直接与 SMTP 服务器通讯，具有非常高的发送速度和效率。

Swiftmailer的特点：

1. Send emails using SMTP, sendmail, postfix or a custom Transport implementation of your own
2. Support servers that require username & password and/or encryption
3. Protect from header injection attacks without stripping request data content
4. Send MIME compliant HTML/multipart emails
5. Use event-driven plugins to customize the library
6. Handle large attachments and inline/embedded images with low memory use
