Follow to comment, there the correct function

    public function ExtractGzip() {

// Raising this value may increase performance
      $buffer_size = 4096; // read 4kb at a time
      $out_file_name = str_replace('.gz', '', $this->selectFile());

// Open our files (in binary mode)
      $file = gzopen($this->selectFile(), 'rb');
      $out_file = fopen($out_file_name, 'wb');

// Keep repeating until the end of the input file
      while(!gzeof($file)) {
        // Read buffer-size bytes
        // Both fwrite and gzread and binary-safe
        fwrite($out_file, gzread($file, $buffer_size));
      }

// Files are done, close files
      fclose($out_file);
      gzclose($file);
    }
