php 邮件发送如何进行的呢？
php邮件发送是通过smtp协议进行的。
下面是一个php邮件发送的类的一个函数。
function sendmail($to, $from, $subject = "", $body = "", $mailtype, $cc = "", $bcc = "", $additional_headers = "")
{
$mail_from = $this->get_address($this->strip_comment($from));
$body = ereg_replace("(^|(rn))(.)", "1.3", $body);
$header = "MIME-Version:1.0rn";
if($mailtype=="HTML"){
$header .= "Content-Type:text/htmlrn";
}
$header .= "To: ".$to."rn";
if ($cc != "") {
$header .= "Cc: ".$cc."rn";
}
$header .= "From: 报名邮件.<".$from.">rn";
$header .= "Subject: ".$subject."rn";
$header .= $additional_headers;
$header .= "Date: ".date("r")."rn";
$header .= "X-Mailer:By Redhat (PHP/".phpversion().")rn";
$utfheader=iconv("UTF-8","GB2312",$header);
list($msec, $sec) = explode(" ", microtime());
$header .= "Message-ID: <".date("YmdHis", $sec).".".($msec*1000000).".".$mail_from.">rn";
$TO = explode(",", $this->strip_comment($to));
if ($cc != "") {
$TO = array_merge($TO, explode(",", $this->strip_comment($cc)));
}
if ($bcc != "") {
$TO = array_merge($TO, explode(",", $this->strip_comment($bcc)));
}
$sent = TRUE;
foreach ($TO as $rcpt_to) {
$rcpt_to = $this->get_address($rcpt_to);
if (!$this->smtp_sockopen($rcpt_to)) {
$this->log_write("Error: Cannot send email to ".$rcpt_to."n");
$sent = FALSE;
continue;
}
if ($this->smtp_send($this->host_name, $mail_from, $rcpt_to, $utfheader, $body)) {
$this->log_write("E-mail has been sent to <".$rcpt_to.">n");
} else {
$this->log_write("Error: Cannot send email to <".$rcpt_to.">n");
$sent = FALSE;
}
fclose($this->sock);
$this->log_write("Disconnected from remote hostn");
}
return $sent;
}
我们如何调用这个类呢？
再看示例
include("sendmail.php");//发送邮件类
####################--发邮件--####################
$smtpserver = "smtp.126.com";//SMTP服务器
$smtpserverport = 25;//SMTP服务器端口
$smtpusermail = "test@126.com";//SMTP服务器的用户邮箱
$smtpuser = "test";//SMTP服务器的用户帐号
$smtppass = "123456";//SMTP服务器的用户密码
$smtpemailto = "dianzhong@126.com";//发送给谁
$mailsubject = $username.'报名!';//邮件主题
$mailtime = date("Y-m-d H:i:s");
$mailbody = $content;//邮件内容
$utfmailbody = iconv("UTF-8","GB2312",$mailbody);//转换邮件编码
$mailtype = "HTML";//邮件格式（HTML/TXT）,TXT为文本邮件
在这里需要一个smtp服务器。我们可以注册一个126的邮箱。 在上面的代码中，修改成你自己注册的邮箱地址和用户名、密码即可。
这样就可以用php发邮件了。
我做了一个用php发邮件的例子。

下载后记得修改里面的邮箱用户名和密码哦。
