I already know php and i also written a framework
I wonder if i should learn laravel or i should learn cakephp ?
Let the battle... i mean answers begin !

Personally, I love php but do not like frameworks. I prefer a more modular approach. Initialize composer and plug in what you would use. In terms of Laravel vs Cakephp, both are fantastic, but I find Laravel a lil more intuitive. Worked on a project that was already using it in the past and it did not take me long to figure out what I needed to get going. Just have fun man!
