Zend Framework入门教程之Zend_Mail用法示例

本文实例讲述了Zend Framework入门教程之Zend_Mail用法。分享给大家供大家参考,具体如下:

Zend_Mail组件提供了通用化的功能来创建和发送文本。

Zend_Mail通过PHP内建的mail()函数或者直接通过SMTP连接来发送邮件。

一个简单的邮件由收件人、主题、邮件内容以及发件人等内容组成。

步骤如下

1.创建对象 2.设置邮件内容 3.发送

案例:

addTo("jiqing9006@126.com","jim"); //添加一个收件人 $my_mail->setSubject("Just a test"); //设置主题 $my_mail->setBodyText("Hello Jim!"); //为邮件设置正文内容 $my_mail->setFrom("706507884@qq.com","jiqing"); //为邮件设置发件人 echo "邮件设置完毕"; echo "

"; echo "邮件收件人为:"; $result = $my_mail->getHeaders(); echo $result['To'][0]; echo "

"; echo "邮件主题为:"; echo $my_mail->getSubject(); echo "

"; echo "邮件内容为:"; $result = $my_mail->getBodyText(); echo $result->getContent(); echo "

"; echo "邮件发件人为:"; echo $my_mail->getFrom(); echo "

"; $my_mail->send();

结果:

function.mail]: Failed to connect to mailserver at "localhost" port 25,verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set()' in C:\zend\library\Zend\Mail\Transport\Sendmail.php:137 Stack trace: #0 C:\zend\library\Zend\Mail\Transport\Abstract.php(348): Zend_Mail_Transport_Sendmail->_sendMail() #1 C:\zend\library\Zend\Mail.php(1194): Zend_Mail_Transport_Abstract->send(Object(Zend_Mail)) #2 D:\xampp\htdocs\test.php(24): Zend_Mail->send() #3 {main} thrown in

C:\zend\library\Zend\Mail\Transport\Sendmail.php

on line

点评:

这里执行不能成功,是因为没有配置好Mail服务器。
