php实现的发送带附件邮件类实例

这篇文章主要介绍了php实现的发送带附件邮件类,是php程序设计中非常常见的实用技巧,实例演示了邮件类及对应的demo示例,需要的朋友可以参考下

本文实例讲述了php实现的发送带附件邮件类的方法，是一个非常实用的功能。分享给大家供大家参考。具体方法如下：

emailclass.php类文件如下：

<?

class CMailFile {



  var $subject;

  var $addr_to;

  var $text_body;

  var $text_encoded;

  var $mime_headers;

  var $mime_boundary = "--==================_846811060==_";

  var $smtp_headers;



  function CMailFile($subject,$to,$from,$msg,$filename,$downfilename,$mimetype = "application/octet-stream",$mime_filename = false) {

    $this->subject = $subject;

    $this->addr_to = $to;

    $this->smtp_headers = $this->write_smtpheaders($from);

    $this->text_body = $this->write_body($msg);

    $this->text_encoded = $this->attach_file($filename,$downfilename,$mimetype,$mime_filename);

    $this->mime_headers = $this->write_mimeheaders($filename, $mime_filename);

  }



  function attach_file($filename,$downfilename,$mimetype,$mime_filename) {

    $encoded = $this->encode_file($filename);

    if ($mime_filename) $filename = $mime_filename;

    $out = "--" . $this->mime_boundary . "\n";

    $out = $out . "Content-type: " . $mimetype . "; name=\"$filename\";\n";

    $out = $out . "Content-Transfer-Encoding: base64\n";

    $out = $out . "Content-disposition: attachment; filename=\"$downfilename\"\n\n";

    $out = $out . $encoded . "\n";

    $out = $out . "--" . $this->mime_boundary . "--" . "\n";

    return $out;

  }



  function encode_file($sourcefile) {

    if (is_readable($sourcefile)) {

      $fd = fopen($sourcefile, "r");

      $contents = fread($fd, filesize($sourcefile));

      $encoded = chunk_split(base64_encode($contents));

      fclose($fd);

    }

    return $encoded;

  }



  function sendfile() {

    $headers = $this->smtp_headers . $this->mime_headers;

    $message = $this->text_body . $this->text_encoded;

    mail($this->addr_to,$this->subject,$message,$headers);

  }



  function write_body($msgtext) {

    $out = "--" . $this->mime_boundary . "\n";

    $out = $out . "Content-Type: text/plain; charset=\"us-ascii\"\n\n";

    $out = $out . $msgtext . "\n";

    return $out;

  }



  function write_mimeheaders($filename, $mime_filename) {

    if ($mime_filename) $filename = $mime_filename;

    $out = "MIME-version: 1.0\n";

    $out = $out . "Content-type: multipart/mixed; ";

    $out = $out . "boundary=\"$this->mime_boundary\"\n";

    $out = $out . "Content-transfer-encoding: 7BIT\n";

    $out = $out . "X-attachments: $filename;\n\n";

    return $out;

  }



  function write_smtpheaders($addr_from) {

    $out = "From: $addr_from\n";

    $out = $out . "Reply-To: $addr_from\n";

    $out = $out . "X-Mailer: PHP3\n";

    $out = $out . "X-Sender: $addr_from\n";

    return $out;

  }

}



/*用法 - 例如:mimetype 为 "image/gif"

  $mailfile = new CMailFile($subject,$sendto,$replyto,$message,$filename,$mimetype);

  $mailfile->sendfile();



  $subject -- 主题

  $sendto -- 收信人地址

  $replyto -- 回复地址

  $message -- 信件内容

  $filename -- 附件文件名

  $downfilename -- 下載的文件名

  $mimetype -- mime类型

*/

?>

Demo示例文件如下：

<?php

  require_once('emailclass.php');



  //发送邮件



  //主題

  $subject = "test send email";



  //收件人

  $sendto = 'abc@163.com';



  //發件人

  $replyto = 'cdf@163.com';



  //內容

  $message = "test send email content";



  //附件

  $filename = 'test.jpg';



  //附件類別

  $mimetype = "image/jpeg";



  $mailfile = new CMailFile($subject,$sendto,$replyto,$message,$filename,$excelname,$mimetype);

  $mailfile->sendfile();

?>

相信本文所述对大家php程序设计的学习有一定的借鉴价值。
