Using php as a client library to access MogileFS and inserting multiple trackers

Hi, Recently I am using php as a client library to access MogileFS. Unlike other programming languages such as Perl or Java, I can only insert “one” tracker to the php code to access MogileFS. I am a little confused about this because basically I should be able to insert multiple trackers to the php code. Only by inserting multiple trackers, I can somehow have the load balance ability between trackers. Therefore, I would like to ask if there will be a newer version of php client library that includes this ability of inserting multiple trackers? I think it will make php library more perfect if this ability could be included. Thanks~~~~ Chu Shiuan
