I am so sorry , I posted this question here, as suggested by one of the users, I googled a few different things online an dhave found a ruby file which has been built for the same purpose. And , if anybody would like to access it, they may check it out online at http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/298382 . And, now I have decided to use this algorithm itself to create such a PHP file. Thank you everybody, for suggestions
