Backup database and email it to me

[TheUnknown]

I'm trying to get my db backed up every 24 ours and emailed to me

 

Here is the code

I set it up on a cron job and I get the email but the file is 0 bytes

Any ideas?

<?php
require_once("backend/config.php");


$datestamp = date("Y-m-d");

$filename = "./backups/{$SITENAME}_SQL_Backup-{$datestamp}.sql.gz";
$to = "tracker-AT-torrentstorage.com";
$from = "noreply@torrentstorage.com";
$subject = "Database Backup (".$datestamp.")";
$body = "Compressed MySQL Backup ({$SITENAME}_SQL_Backup-{$datestamp}.sql.gz) Attached.";

class mime_mail
{
   var $parts;
   var $to;
   var $from;
   var $headers;
   var $subject;
   var $body;

  

   function mime_mail() {
      $this->parts = array();
      $this->to =  "";
      $this->from =  "";
      $this->subject =  "";
      $this->body =  "";
      $this->headers =  "";
   }


  

   function add_attachment($message, $name =  "", $ctype ="application/octet-stream") {
      $this->parts[] = array (
            "ctype" => $ctype,
            "message" => $message,
            "encode" => $encode,
            "name" => $name
                           );
   }

  

   function build_message($part) {
      $message = $part[ "message"];
      $message = chunk_split(base64_encode($message));
      $encoding =  "base64";
      return  "Content-Type: ".$part[ "ctype"].
         ($part[ "name"]? "; name = \"".$part[ "name"].
         "\"" :  "").

         "\nContent-Transfer-Encoding: $encoding\n\n$message\n";
   }

  

   function build_multipart() {
      $boundary =  "b".md5(uniqid(time()));
      $multipart =
         "Content-Type: multipart/mixed; boundary = $boundary\n\nThis is a
MIME encoded message.\n\n--$boundary";

         for($i = sizeof($this->parts)-1; $i >= 0; $i--)
      {
         $multipart .=  "\n".$this->build_message($this->parts[$i]).
            "--$boundary";
      }
      return $multipart.=  "--\n";
   }

  


   function get_mail($complete = true) {
      $mime =  "";
      if (!empty($this->from))
         $mime .=  "From: ".$this->from. "\n";
      if (!empty($this->headers))
         $mime .= $this->headers. "\n";

      if ($complete) {
         if (!empty($this->to)) {
            $mime .= "To: $this->to\n";
         }
         if (!empty($this->subject)) {
            $mime .= "Subject: $this->subject\n";
         }
      }

      if (!empty($this->body))
         $this->add_attachment($this->body,  "",  "text/plain");
      $mime .=  "MIME-Version: 1.0\n".$this->build_multipart();

      return $mime;
   }

  

   function send() {
      $mime = $this->get_mail(false);
      mail($this->to, $this->subject,  "", $mime);
   }
}; 



$command = "mysqldump -u $mysql_user --password=$mysql_pass $mysql_db | gzip > $filename";

$result = system($command);

$data = implode("",file($filename));

$mail = new mime_mail;

$content_type = "application/octet-stream";

$mail->from = $from;
$mail->to = $to;
$mail->subject = $subject;
$mail->body = $body;
$mail->add_attachment($data, "{$SITENAME}-".$datestamp.".sql.gz", $content_type);
$mail->send();

?>

Is that file being written (the gzip'd one), and if so, where? From skimming over i'm not convinced that it's being done properly.

I have no idea

 

This seems to work just fine for other people that run this code
