PHP Trim... not working?

[m002.p]

Hi all.

Im working on a script which keeps a memory of what text source has been read by determining which is new or old material using a txt log.

The code I use to determine the search material and create / update the file and keep the .txt file as short as possible doesnt appear to be working.

I cant see an error with my trim function so I am stumped as to why the code keeps logging source material and making the file larger and larger decreasing reliability, and not removing old source material.

PHP Code:

  // Creating new log as a string
  $_new = "";
  foreach($log_console as $key=>$arr)
  {
    if($_c[$key]) foreach($arr[0] as $k=>$v)
    {
      $add = 1;
      foreach($_olds as $_k=>$_v)
      {
        if($_v == $v)
        {
          $_new .= "{$v}\n";
          unset($log_console[$key][0][$k],$log_console[$key][1][$k],$log_console[$key][2][$k],$log_console[$key][3][$k],$log_console[$key][4][$k]);
          $_c[$key]--;
          unset($_olds[$_k]);
          $add = 0;
          break;
        }
      }
      if($add) $_new .= "{$v}\n";
    }
  }
  foreach($_olds as $_k=>$_v) { $_new .= "{$_v}\n"; }

  // Arrays
  $log_console_players = array_merge($log_console['say'][1],$log_console['teamsay'][1]);
  $log_console_text = array_merge($log_console['say'][2],$log_console['teamsay'][2]);

  // Saving new log to the file
  if($fw = @fopen("{$gameservername} Console.log",'w')) { @fwrite($fw,trim($_new)); @fclose($fw); } 


Any ideas why this might be happening?

Thanks

Matt

I don't really understand what you're trying to do, but trim() only removes white-space, or another character if specified.
