Developing text-based browser game?

Hello,
Few years ago i started to develop a browser based game, but i never finished because i make it only when i had time and it was just for fun and practice until i learn more. That was around 6-7 years ago. The game is developed mostly on PHP with little javascript, but the code is written just awful… Now i am thinking to re-write the whole game with the new language versions, but i wonder is it a good idea to use any framework on it or i shouldn't? I was thinking about codeigniter or symfony… Do you have any opinion / advice about it ?
