1. 使用 mail() 函数
没什么好讲的，就是使用系统自带的smtp系统来发送，一般是使用sendmail来发。这个按照各个系统不同而定。使用参考手册。
2. 使用管道的形式
昨天刚测试成功，使用本地的qmail来发送邮件。
复制代码 代码如下:
/* 使用qmail发送邮件函数 */
function send_check_mail($email, $subject,$uid,$buffer)
{
$command = "/var/qmail/bin/qmail-inject ".$email; //qmail程式地址,$email是要发送的地址
$handle = popen($command, "w"); //打开管道
if (!$handle) {
return false;
}
$from = "webmaster@unixsky.net"; //发件人
fwrite($handle, "From: ".$from."＼n"); //往管道写数据
fwrite($handle, "Return-Path: ".$from."＼n");
fwrite($handle, "To: ".$uid."＼n");
fwrite($handle, "Subject: ".$subject."＼n");
fwrite($handle, "Mime-Version: 1.0＼n");
fwrite($handle, "Content-Type: text/html; charset=＼"gb2312＼"＼n＼n");
fwrite($handle, $buffer."＼n");
pclose($handle); //关闭管道
return true;
}
------------------测试发送邮件：
//发送邮件
$subject = "测试邮件";
$uid = $_POST['uid']; //from信息
$content = "<html><body>".$u_email
." 你好！<br><br>谢谢，本邮件测试！<br</body></html>"; //内容信息
$u_email = "hren@yahoo.com.cn"; //发送到的邮箱
if (send_check_mail($u_email, $subject, $uid, $content)) {
echo "恭喜！发送投票邮件到你的邮箱！<br><br>请检查你的邮箱：<font color=#CC0033>".$u_email." </font><br><br>". $close;
} else {
echo "非常不幸，发送投票邮件到你的邮箱失败，请重试或联系研发人员。<br><br>". $close;
}
当然，也能使用相同的方法来处理sendmail的进程来发送邮件。
下面代码示例：
复制代码 代码如下:
<?php
$pp = popen("/usr/sbin/sendmail -t", "w") or die("Cannot fork sendmail");
fputs($pp, "To: sterling@designmultimedia.com＼r＼n");
fputs($pp, "Reply-to: $senders_email＼r＼n");
fputs($pp, "From: $senders_email＼r＼n");
fputs($pp, "Subject The Results of your form＼r＼n＼r＼n");
fputs($pp, "$senders_email sent the fllowing comments:＼r＼n");
fputs($pp, $comments);
pclose($pp) or die("Cannot close pipe to sendmail");
?>
其实这种管道的方法比较底层，取决于你所调用程式的稳定性。所以是一种可选的发送邮件的方式。
3. 使用phpmailer类
是个开源的发送邮件类，主站：
里面是两个文件，一个是class.smtp.php，更有以个是class.phpmailer.php
另外加上官方网站的使用方法：
Examples using phpmailer
1. Advanced ExampleThis demonstrates sending out multiple email messages with binary attachments from a MySQL database with multipart/alternative support.
复制代码 代码如下:
require("class.phpmailer.php");
$mail = new phpmailer();
$mail->From = "list@example.com";
$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");
$query?=?SELECT full_name, email,?hoto?ROM employee?HERE?d=$id";
$result??MYSQL_QUERY($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();
}
