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。
