Today, I am reverse python code to PHP. I run php code in command line. Oh!!! python is very faster than PHP. I waited 30 seconds for convert file. When I used Python,it’s just 1 second for convert file. Same Algorithm, same idea and same file size. However, python is very faster than PHP. We shall not use PHP for search engine, crawling program and Giga bytes file converting.Imm.. I need to learn Python.
