php邮件发送模块,支持批量发送

php本身提供了一个邮件发送函数mail,可以在程序中直接发送电子邮件,不过该函数要求服务器支持sendmail或者必须设置一台不需要中继的邮件发送服务器,但现在要找到一台不需要身份验证的邮件发送中继几乎不可能,所以使用mail函数往往无法成功发送email. 自己如果熟悉SMTP协议,结合socket功能就可以编写高效稳定的邮件发送程序,但对一般用户来说太困难.好在互联网上已经有很多别人编写好的邮件发送模块,我们只需要下载后简单调用即可,十分方便. 以下文件: email.class.php < ? class smtp { /* Public Variables */ public $smtp_port; public $time_out; public $host_name; public $log_file; public $relay_host; public $debug; public $auth; public $user; public $pass; /* Private Variables */ private $sock; /* Constractor */ function smtp($relay_host = "", $smtp_port = 25,$auth = false,$user,$pass) { $this->debug = FALSE; $this->smtp_port = $smtp_port; $this->relay_host = $relay_host; $this->time_out = 30; //is used in fsockopen() # $this->auth = $auth;//auth $this->user = $user; $this->pass = $pass; # $this->host_name = "localhost"; //is used in HELO command $this->log_file =""; $this->sock = FALSE; } /* Main Function */ function sendmail($to, $from, $subject = "", $body = "", $mailtype, $cc = "", $bcc = "", $additional_headers = "") { $mail_from = $this->get_address($this->strip_comment($from)); $body = preg_replace("/(^|(\r\n))(\\.)/", "\\1.\\3", $body); $header .= "MIME-Version:1.0\r\n"; if($mailtype=="HTML"){ $header .= "Content-Type:text/html\r\n"; } $header .= "To: ".$to."\r\n"; if ($cc != "") { $header .= "Cc: ".$cc."\r\n"; } $header .= "From: $from< ".$from.">\r\n"; $header .= "Subject: ".$subject."\r\n"; $header .= $additional_headers; $header .= "Date: ".date("r")."\r\n"; $header .= "X-Mailer:By Redhat (PHP/".phpversion().")\r\n"; list($msec, $sec) = explode(" ", microtime()); $header .= "Message-ID: < ".date("YmdHis", $sec).".".($msec*1000000).".".$mail_from.">\r\n"; $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, $header, $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 host\n"); } echo "

在需要发送邮件的地方使用以下方法 < ?php require_once ('email.class.php'); //########################################## $smtpserver = "smtp.qq.com";//SMTP服务器 $smtpserverport =25;//SMTP服务器端口 $smtpusermail = "34******@qq.com";//SMTP服务器的用户邮箱 $smtpemailto = "***@7cuu.com";//收件人 $smtpuser = "34******@qq.com";//SMTP服务器的用户帐号如填写******@blog.7cuu.com自己的邮箱 $smtppass = "**********";//SMTP服务器的用户密码 $mailsubject = "邮件标题";//邮件主题 $mailbody = "hello world 悠悠博客http://blog.7cuu.com";//邮件内容 $mailtype = "HTML";//邮件格式(HTML/TXT),TXT为文本邮件 ########################################## $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//这里面的一个true是表示使用身份验证,否则不使用身份验证. $smtp->debug = false;//是否显示发送的调试信息(true,false) $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype); ?>
