Ask HN: What are PHP's equivalents to Python's top tools?

I have been a happy Python user for years and super thankful for the plethora of good tools in the Python environment. However I sometimes have to use some PHP and still feel like I'm in the 90ies when it comes to the tools I use. I skimmed through Josh Lockhart's Modern PHP, but still I have not found many alternatives to the tools I love.

I'm sure, however, that these exist. So, what are the closest best practice equivalents, for...

- Creating separate dev environments using `Virtualenv`? - Installing packages in these envs using `pip`? How can I use composer in that workflow? - Enabling persistence in a super simple way using `dataset`? - Handling requests using `requests`? - Creating beautiful command line interfaces using `click`? - Getting an overview of good practices via http://docs.python-guide.org/en/latest/?

Probably you can come up with even more great workflow tools in Python and their equivalent in PHP.
