Why do I need to use a popular framework?

Question

I\'ve been a PHP developer for many years now, with many tools under my belt; tools that I\'ve either developed myself, or free-to-use solutions that I have learned to trust

Answer 1

Can you solve the problems you are given have with your code faster and more reliably than public frameworks?

If yes, then keep using your own.

If no, then find the framework that does a better job and run with it for that project.

It all comes down to which codebase gets the job done better(for the value of better given by the client. ;) )
