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(); 

									?>
