      Subject: [bang-phpug] php script to download the files


      I am trying to write a script to download zip file(20 MB). but after downloading content of 5 or 6 MB, the script stops and failed to download the entire file.
      I am using the following function
      <?php
      function dl_file_resumable( $file, $is_resume=TRUE)
      {
      //First, see if the file exists
      if (!is_file($file) )
      {
      die("<b>404 File not found!</b>") ;
      }

      //Gather relevent info about file
      $size = filesize($file) ;
      $fileinfo = pathinfo($file) ;

      //workaround for IE filename bug with multiple periods / multiple dots in filename
      //that adds square brackets to filename - eg. setup.abc.exe becomes setup[1].abc. exe
      $filename = (strstr($_SERVER[ 'HTTP_USER_ AGENT'], 'MSIE')) ?
      preg_replace( '/\./', '%2e', $fileinfo['basename '], substr_count( $fileinfo[ 'basename' ], '.') - 1) :
      $fileinfo['basename '];

      $file_extension = strtolower($ path_info[ 'extension' ]);

      //This will set the Content-Type to the appropriate setting for the file
      switch($file_ extension)
      {
      case 'exe': $ctype='application /octet-stream' ; break;
      case 'zip': $ctype='application /zip'; break;
      case 'mp3': $ctype='audio/ mpeg'; break;
      case 'mpg': $ctype='video/ mpeg'; break;
      case 'avi': $ctype='video/ x-msvideo' ; break;
      default: $ctype='application /force-download' ;
      }

      //check if http_range is sent by browser (or download manager)
      if($is_resume && isset($_SERVER[ 'HTTP_RANGE' ]))
      {
      list($size_unit, $range_orig) = explode('=', $_SERVER['HTTP_ RANGE'], 2);

      if ($size_unit == 'bytes')
      {
      //multiple ranges could be specified at the same time, but for simplicity only serve the first range
      //http://tools. ietf.org/ id/draft- ietf-http- range-retrieval- 00.txt
      list($range, $extra_ranges) = explode(',', $range_orig, 2);
      }
      else
      {
      $range = '';
      }
      }
      else
      {
      $range = '';
      }

      //figure out download piece from range (if set)
      list($seek_start, $seek_end) = explode('-', $range, 2);

      //set start and end based on range (if set), else set defaults
      //also check for invalid ranges.
      $seek_end = (empty($seek_ end)) ? ($size - 1) : min(abs(intval( $seek_end) ),($size - 1));
      $seek_start = (empty($seek_ start) || $seek_end < abs(intval($ seek_start) )) ? 0 : max(abs(intval( $seek_start) ),0);

      //add headers if resumable
      if ($is_resume)
      {
      //Only send partial content header if downloading a piece of the file (IE workaround)
      if ($seek_start > 0 || $seek_end < ($size - 1))
      {
      header('HTTP/ 1.1 206 Partial Content');
      }

      header('Accept- Ranges: bytes');
      header('Content- Range: bytes '.$seek_start. '-'.$seek_ end.'/'.$ size);
      }

      //headers for IE Bugs (is this necessary?)
      //header("Cache- Control: cache, must-revalidate" );
      //header("Pragma: public");

      header('Content- Type: ' . $ctype);
      header('Content- Disposition: attachment; filename="' . $filename . '"');
      header('Content- Length: '.($seek_end - $seek_start + 1));

      //open the file
      $fp = fopen($file, 'rb');
      //seek to start of missing part
      fseek($fp, $seek_start) ;

      //start buffered download
      while(!feof( $fp))
      {
      //reset time limit for big files
      set_time_limit( 0);
      print(fread( $fp, 1024*8));
      flush();
      ob_flush();
      }

      fclose($fp);
      exit;
      }

      ?>

      pls help me to correct the code and download the zip file properly.
      thanks in advance.

        I have not access to the php.ini file as it is shared server.
        I had increase the memory_limit by ini_set function to 64 MB. but still no success.

        I have doubt, why should i increase the max_file_upload as I am not trying to upload the file.
        I am trying to download the zip file using php script
