这篇文章主要介绍了php基于socket实现SMTP发送邮件的方法,实例分析了php采用socket实现smtp发送邮件的原理与技巧,具有一定参考借鉴价值,需要的朋友可以参考下 本文实例讲述了php基于socket实现SMTP发送邮件的方法。分享给大家供大家参考。具体分析如下： php采用socket通过SMTP发送邮件。 用的是php的php-sockets扩展，可以发送纯文本和html格式的邮件。代码如下： 代码如下: <?php /** * 邮件发送类 * 支持发送纯文本邮件和HTML格式的邮件 * @example * $config = array( * "from" => "*****", * "to" => "***", * "subject" => "test", * "body" => "<b>test</b>", * "username" => "***", * "password" => "****", * "isHTML" => true * ); * * $mail = new MySendMail(); * * $mail->setServer("smtp.126.com"); * * $mail->setMailInfo($config); * if(!$mail->sendMail()) { * echo $mail->error(); * return 1; * } */ class MySendMail { /** * @var 邮件传输代理用户名 * @access private */ private $_userName; /** * @var 邮件传输代理密码 * @access private */ private $_password; /** * @var 邮件传输代理服务器地址 * @access protected */ protected $_sendServer; /** * @var 邮件传输代理服务器端口 * @access protected */ protected $_port=25; /** * @var 发件人 * @access protected */ protected $_from; /** * @var 收件人 * @access protected */ protected $_to; /** * @var 主题 * @access protected */ protected $_subject; /** * @var 邮件正文 * @access protected */ protected $_body; /** * @var 是否是HTML格式的邮件 * @access protected */ protected $_isHTML=false; /** * @var socket资源 * @access protected */ protected $_socket; /** * @var 错误信息 * @access protected */ protected $_errorMessage; public function __construct($from="", $to="", $subject="", $body="", $server="", $username="", $password="",$isHTML="", $port="") { if(!empty($from)){ $this->_from = $from; } if(!empty($to)){ $this->_to = $to; } if(!empty($subject)){ $this->_subject = $subject; } if(!empty($body)){ $this->_body = $body; } if(!empty($isHTML)){ $this->_isHTML = $isHTML; } if(!empty($server)){ $this->_sendServer = $server; } if(!empty($port)){ $this->_port = $port; } if(!empty($username)){ $this->_userName = $username; } if(!empty($password)){ $this->_password = $password; } } /** * 设置邮件传输代理 * @param string $server 代理服务器的ip或者域名 * @param int $port 代理服务器的端口，smtp默认25号端口 * @param int $localPort 本地端口 * @return boolean */ public function setServer($server, $port=25) { if(!isset($server) || empty($server) || !is_string($server)) { $this->_errorMessage = "first one is an invalid parameter"; return false; } if(!is_numeric($port)){ $this->_errorMessage = "first two is an invalid parameter"; return false; } $this->_sendServer = $server; $this->_port = $port; return true; } /** * 设置邮件 * @access public * @param array $config 邮件配置信息 * 包含邮件发送人、接收人、主题、内容、邮件传输代理的验证信息 * @return boolean */ public function setMailInfo($config) { if(!is_array($config) || count($config) < 6){ $this->_errorMessage = "parameters are required"; return false; } $this->_from = $config['from']; $this->_to = $config['to']; $this->_subject = $config['subject']; $this->_body = $config['body']; $this->_userName = $config['username']; $this->_password = $config['password']; if(isset($config['isHTML'])){ $this->_isHTML = $config['isHTML']; } return true; } /** * 发送邮件 * @access public * @return boolean */ public function sendMail() { $command = $this->getCommand(); $this->socket(); foreach ($command as $value) { if($this->sendCommand($value[0], $value[1])) { continue; } else{ return false; } } $this->close(); //其实这里也没必要关闭，smtp命令：QUIT发出之后，服务器就关闭了连接，本地的socket资源会自动释放 echo 'Mail OK!'; return true; } /** * 返回错误信息 * @return string */ public function error(){ if(!isset($this->_errorMessage)) { $this->_errorMessage = ""; } return $this->_errorMessage; } /** * 返回mail命令 * @access protected * @return array */ protected function getCommand() { if($this->_isHTML) { $mail = "MIME-Version:1.0/r/n"; $mail .= "Content-type:text/html;charset=utf-8/r/n"; $mail .= "FROM:test<" . $this->_from .
