Got this website for PHP LZW encoding and decoding 
http://whoyouknow.co.uk/uni/datacompression/lzw.php
It’s open source
Well still have to solve the problem on how exact the compressed data is being used.
- PHP compress data —> AS decompress data for execution.
- AS compress data —> PHP decompress data and store in database.
NOTE: —> = transfer of data thru internet
