php實現在網站裡面添加郵件發送的功能_php執行個體

下面夏日部落格來講下如何在網站裡面添加一個郵件發送的功能。
首先需要下載一個smtp 的 php 郵件發送類，代碼如下:

<?phpclass 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 "

";     }   }  function get_attach_type($image_tag) { //    $filedata = array();      $img_file_con=fopen($image_tag,"r");   unset($image_data);   while ($tem_buffer=AddSlashes(fread($img_file_con,filesize($image_tag))))   $image_data.=$tem_buffer;   fclose($img_file_con);    $filedata['context'] = $image_data;   $filedata['filename']= basename($image_tag);   $extension=substr($image_tag,strrpos($image_tag,"."),strlen($image_tag)-strrpos($image_tag,"."));   switch($extension){     case ".gif":       $filedata['type'] = "image/gif";       break;     case ".gz":       $filedata['type'] = "application/x-gzip";       break;     case ".htm":       $filedata['type'] = "text/html";       break;     case ".html":       $filedata['type'] = "text/html";       break;     case ".jpg":       $filedata['type'] = "image/jpeg";       break;     case ".tar":       $filedata['type'] = "application/x-tar";       break;     case ".txt":       $filedata['type'] = "text/plain";       break;     case ".zip":       $filedata['type'] = "application/zip";       break;     default:       $filedata['type'] = "application/octet-stream";       break;   }   return $filedata;   }  } // end class ?>

這類的郵件發送類網上有許多，可以挑一款自己喜歡的就行，將以上的代碼儲存為 ZC_Email.class.php 檔案，然後在使用的時候直接 include_once("ZC_Email.class.php") 就可以了，代碼如下:

<?php include_once("ZC_Email.class.php");?>

這是將郵件的發送類已經嵌入到頁面中了，下一步就要在頁面進行內容的發送了，我這裡的系統是使用者購買成功後進行發送，執行個體代碼如下:

//空間購買成功發送郵件    $smtpserver = "smtp.163.com";//SMTP伺服器     $smtpserverport =25;//SMTP伺服器連接埠     $smtpusermail = "xiariboke@163.com";//SMTP伺服器的使用者郵箱     $smtpemailto = "xiariboke@qq.com";//發送給誰     $smtpuser = "xiariboke@163.com";//SMTP伺服器的使用者帳號     $smtppass = "xiariboke";//SMTP伺服器的使用者密碼     $mailsubject = "精品門業網香港空間購買";//郵件主題     $mailbody = "成功購買香港空間 $size M空間，購買網域名稱為：$domain 購買時間為:".format_date(time(),2)." 到期時間為: $lasttime ".format_date(time(),5);//郵件內容     $mailtype = "TXT";//郵件格式（HTML/TXT）,TXT為文本郵件     ##########################################     $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//這裡面的一個true是表示使用身分識別驗證,否則不使用身分識別驗證.     $smtp->debug = false;//是否顯示發送的調試資訊     $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);     //郵件發送結束     showmsg('購買成功！','ZC_Link_List.php?sort=2');

其中 SMTP 伺服器的使用者郵箱和密碼自己要設定好，這是發給指定的一個郵箱，當然可以自訂改成自己的，這裡面的變數都是我網站內使用的，如果不需要可以自己稍微修改一下，這裡不多講了。
希望本文所述對大家學習php程式設計有所協助。
