php如何发送邮件

[subendong]

在网上找了很多代码，都没用。
哪位能给个实例？谢谢！！！
补充：请不要讲理论，浪费大家时间，谢谢！！

一般用mail函数的话，需要配置很多信息，机器上还要有邮件服务，很麻烦！
可以用smtp自己写一个。

分享一个写好的类，直接调用就行了。

这个是测试代码。使用前改还邮箱跟密码。

<?php
include_once("smtp.class.php");
$smtpserver = "smtp.qq.com";//SMTP服务器
$smtpserverport =25;//SMTP服务器端口
$smtpusermail = "12345qq.com";//SMTP服务器的用户邮箱
$smtpemailto = "[e-mail]";//发送给谁
$smtpuser = "12345";//SMTP服务器的用户帐号
$smtppass = "12345";//SMTP服务器的用户密码
$mailsubject = "测试邮件系统";//邮件主题
$mailbody = "<h1> 这是一个测试程序 </h1>";//邮件内容
$mailtype = "HTML";//邮件格式（HTML/TXT）,TXT为文本邮件
if($_POST[submit])
{
	$smtp= new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);
	$smtp->debug = FALSE;//是否显示发送的调试信息
	$smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
}
?>


  <form action="test.php" method="post">

学习学习~~回复内容太短了！ 不会吧

[jeremyadison]

phpmailer 已有人回复的很详细了

[hero5460]

http://sourceforge.net/projects/phpmailer/ 去下载一个phpmailer

[subendong]

ol_beta说的方法我试了，可以。
但是用phpmailer我还不清楚是怎么回事。
phpmailer是一个类吗？？

[iinbase]

phpmailer 一个很好的类啊
如果 楼主使用 虚拟主机的话， 提供商 一般都会 提供mail函数支持， 直接用mail函数就可以了 呵呵

[arfeng75]

一般用MAIL函数吧.

[peterlwx]

php发送邮件比较麻烦，比较直接简单的办法是到：http://sourceforge.net/projects/phpmailer/ 去下载一个phpmailer，然后通过以下程序发送邮件。
require("common/class.phpmailer.php");

$mail = new PHPMailer(); //建立邮件发送类
$address = "[e-mail]";
$mail->IsSMTP(); // 使用SMTP方式发送
$mail->Host = "smtp.qq.com"; // 您的企业邮局域名
$mail->SMTPAuth = true; // 启用SMTP验证功能
$mail->Username = "[e-mail]"; // 邮局用户名(请填写完整的email地址)
$mail->Password = "@#$%^%$#"; // 邮局密码

$mail->From = "[e-mail]"; //邮件发送者email地址
$mail->FromName = "peterlee";
$mail->AddAddress($address, "");//收件人地址，可以替换成任何想要接收邮件的email信箱,格式是AddAddress("收件人email","收件人姓名")
//$mail->AddReplyTo("", "");

//$mail->AddAttachment("/var/tmp/file.tar.gz"); // 添加附件
//$mail->IsHTML(true); // set email format to HTML //是否使用HTML格式

$mail->Subject = "验证邮件"; //邮件标题
$mail->Body = "Hello,这是测试邮件"; //邮件内容
$mail->AltBody = "This is the body in plain text for non-HTML mail clients"; //附加信息，可以省略

$mail->Send();

希望能对你有所帮助。

[cxxlp]

我有发送和接收mail 的实例，如有需要可以联系我 [e-mail]

[sciolist]

给你一个sample

require("class.phpmailer.php");

$mail = new phpmailer();

$mail->From     = "[e-mail]";
$mail->FromName = "List manager";
$mail->Host     = "smtp1.example.com;smtp2.example.com";
$mail->Mailer   = "smtp";

@MYSQL_CONNECT("localhost","root","password");
@mysql_select_db("my_company");
$query  = "SELECT full_name, email,爌hoto燜ROM employee燱HERE爄d=$id";
$result =燖MYSQL_QUERY($query);

while ($row = mysql_fetch_array ($result))
{
    // HTML body
    $body  = "Hello <font size=\"4\">" . $row["full_name"] . "</font>, <p>";
    $body .= "<i>Your</i> personal photograph to this message.<p>";
    $body .= "Sincerely, <br>";
    $body .= "phpmailer List manager";

    // Plain text body (for mail clients that cannot read HTML)
    $text_body  = "Hello " . $row["full_name"] . ", \n\n";
    $text_body .= "Your personal photograph to this message.\n\n";
    $text_body .= "Sincerely, \n";
    $text_body .= "phpmailer List manager";

    $mail->Body    = $body;
    $mail->AltBody = $text_body;
    $mail->AddAddress($row["email"], $row["full_name");
    $mail->AddStringAttachment($row["photo"], "YourPhoto.jpg");

    if(!$mail->Send())
        echo "There has been a mail error sending to " . $row["email"] . "<br>";

    // Clear all addresses and attachments for next loop
    $mail->ClearAddresses();
    $mail->ClearAttachments();
}
