Zend Framework入门教程之Zend_Mail用法示例

<?php
require_once "Zend/Mail.php";
$my_mail = new Zend_Mail();             //创建一个对象
$my_mail->addTo("jiqing9006@126.","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.","jiqing");   //为邮件设置发件人
echo "邮件设置完毕";
echo "<p>";
echo "邮件收件人为";
$result = $my_mail->getHeaders();
echo $result['To'][0];
echo "<p>";
echo "邮件主题为";
echo $my_mail->getSubject();
echo "<p>";
echo "邮件内容为";
$result = $my_mail->getBodyText();
echo $result->getContent();
echo "<p>";
echo "邮件发件人为";
echo $my_mail->getFrom();
