Recently I’ve read about namespaces and how they are beneficial. I’m currently creating a project in Laravel and trying to move from class map autoloading to namespacing. However, I can’t seem to grasp what the actual difference is between PSR-0 and PSR-4.
Some resources that I’ve read are…
- Battle of the Autoloaders
- Laracasts PSR-4 autoloading
- PSR-0
- PSR-4
What I understand:
- PSR-4 does not convert underscores to directory separators
- Certain specific rules of composer cause the directory structure to become complex which in turn makes PSR-0 namespacing verbose and thus PSR-4 was created
Examples explaining the difference would be appreciated.
