         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：
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：
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。
