Porting of a huge web application from ZF1 to Laravel 5.5.

In summary:
1. approx. 200,000 lines of spaghetti code (ZF1)
2. approx. 2500 custom Javascript files
3. approx. 600 CSS files
4. hundreds of node modules and libraries
5. 12 different layouts (Home, Member, Admin,...)
6. ...
7. ...
8. ...
...

I've got six days to get this done. God help me.

At the moment I'm working on a project where every line of code is actually garbage. However, the client insists on continuing to use ZF1.

Zend_Locale is a mess. I've been sitting on it for five hours and nothing's working.

I finally! managed, after several annoying phone calls and dozens of emails, to convince the client to switch from ZF1 to another framework after spending several hours setting up Zend_Locale, which, as already predicted, didn't work properly.

I've already written a rant about it.

Project size is approx. 200,000 lines of ZF1 code. ZF3 would be a possibility, but I don't know what the guys from Zend will do with it in the future. The community doesn't seem to be that big either.

What framework would you suggest for PHP at the moment?
