PHP implementation of send with Attachment message class instance _php tips

This article describes the implementation of PHP to send the message class with the attachment method, is a very useful function. Share to everyone for your reference. The specific methods are as follows:

The emailclass.php class files are as follows:

?  
  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 = $this->encode_file ($fi 
    Lename); 
    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"; $out = $out. $encoded. 
    "\ n"; $out = $out. "--" . $this->mime_boundary. "--" . 
    "\ n"; 
  return $out;  
      The function Encode_file ($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, $headers); The function Write_body ($msgtext) {$out = "-". $this->mime_boundary.  
    "\ n"; $out = $out. "Content-type:text/plain; Charset=\ "Us-ascii\"\ n '; $out = $out. $msgtext.  
    "\ n";  
  return $out;  
    The function write_mimeheaders ($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";  
  return $out;  
    The function write_smtpheaders ($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; }/* Usage-for example: MimeType is "image/gif" $mailfile = new Cmailfile ($subject, $sendto, $replyto, $message, $filename, $mime 
  Type); 
 
  $mailfile->sendfile (); $subject--Topic $sendto--the addressee address $replyto--reply address $message--the contents of the letter $filename--attachment file name $downfilename--Downloaded files 
  Name$mimetype-MIME type/?>  

Demo sample files are as follows:

<?php 
  require_once (' emailclass.php '); 
 
  Send mail 
   
  //topic 
  $subject = "Test send email"; 
 
  Recipient 
  $sendto = ' abc@163.com '; 
   
  The inventor 
  $replyto = ' cdf@163.com '; 
   
  Contents 
  $message = "Test send email content"; 
   
  Annex 
  $filename = ' test.jpg '; 
   
  Annex Types 
  $mimetype = "Image/jpeg"; 
 
  $mailfile = new Cmailfile ($subject, $sendto, $replyto, $message, $filename, $excelname, $mimetype);  
  $mailfile->sendfile ();
