PHP发信有很多种方式，可以使用
1、脚本自带的函数sendmail()
2、可以使用Linux的命令SendMail
3、自己实现socket与SMTP服务器使用命令通信发信
4、使用第三方现有PHP邮件类库
前两种都需要环境支持且需要已配置好邮件帐户信息等等。
由于前两种移植性的关系，我们暂不考虑，本文我们采用网络上最简短的库，你可以任意修改它的PHP源代码。
类库文件：SMTPclass.php
|
<?php class SMTPClient {
function SMTPClient ($SmtpServer, $SmtpPort, $SmtpUser, $SmtpPass, $from, $to, $subject, $body) { $this->SmtpServer = $SmtpServer; $this->SmtpUser = base64_encode ($SmtpUser); $this->SmtpPass = base64_encode ($SmtpPass); $this->from = $from; $this->to = $to; $this->subject = $subject; $this->body = $body;
if ($SmtpPort == "") { $this->PortSMTP = 25; } else { $this->PortSMTP = $SmtpPort; } } function SendMail () { if ($SMTPIN = fsockopen ($this->SmtpServer, $this->PortSMTP)) { fputs ($SMTPIN, "EHLO ".$HTTP_HOST."\r\n"); $talk["hello"] = fgets ( $SMTPIN, 1024 ); fputs($SMTPIN, "auth login\r\n"); $talk["res"]=fgets($SMTPIN,1024); fputs($SMTPIN, $this->SmtpUser."\r\n"); $talk["user"]=fgets($SMTPIN,1024); fputs($SMTPIN, $this->SmtpPass."\r\n"); $talk["pass"]=fgets($SMTPIN,256); fputs ($SMTPIN, "MAIL FROM: <".$this->from.">\r\n"); $talk["From"] = fgets ( $SMTPIN, 1024 ); fputs ($SMTPIN, "RCPT TO: <".$this->to.">\r\n"); $talk["To"] = fgets ($SMTPIN, 1024); fputs($SMTPIN, "DATA\r\n"); $talk["data"]=fgets( $SMTPIN,1024 ); fputs($SMTPIN, "Content-Type: text/html; charset=\"UTF-8\";\r\n"); $talk["data"]=fgets( $SMTPIN,1024 ); fputs($SMTPIN, "To: <".$this->to.">\r\nFrom: <".$this->from.">\r\nSubject:".$this->subject."\r\n\r\n\r\n".$this->body."\r\n.\r\n"); $talk["send"]=fgets($SMTPIN,256); //CLOSE CONNECTION AND EXIT ... fputs ($SMTPIN, "QUIT\r\n"); fclose($SMTPIN); } return $talk; } } ?> |
类库文件配置文文件2 ：SMTPconfig.php
|
<?php //Server Address $SmtpServer="smtp.garmin.com"; $SmtpPort="25"; //default $SmtpUser="username"; $SmtpPass="password"; ?> |
然后可以就可以写一个PHP简单页面让其调用访问了这些类即可（下代码）：
|

echo "<font color=red size='+3'>邮件已经成功发送</font>"; } ?> </body></html> |
