The `lib/php` directory is too deep to navigate.
Before, `TBufferedTransport.php` is located at `lib/php/lib/Thrift/Transport`, which is five level. and `lib/php/lib` has only `Thrift` folder. So, I think it's unnecessary.
After, `lib/php/lib/Transport` is four level.
And ClassLoader works.
BTW, if the deep directory is necessary, I can add it back.
