Easy. It's called Django. :-D
The HttpRequest object is automatically populated with both GET and POST
values when Django parses the request from the browser, and handles
multiple values for the same key just fine.
https://docs.djangoproject.com/en/1.9/ref/request-response/#django.http.HttpRequest.GET
Usually this object is made available as a variable called request in a
function-based view, or is available via self.request in a class-based view.
To get multiple values for the same key, simply access that key multiple
times (see the QueryDict link in the section I linked above), usually as
part of a loop. The QueryDict (request.GET) acts like a Python generator.
Usually you access the keys using .get() calls so that a missing or empty
key return None instead of raising an exception:
fn = self.request.GET.get('first_name')
This part of the tutorial has example usage:
https://docs.djangoproject.com/en/1.9/intro/tutorial04/#write-a-simple-form
It uses request.POST, but it works exactly the same way.
On a side note, nothing you've mentioned is specific to PHP, rather it is
all part of the HTTP protocol. The languages/frameworks just have different
methods of accessing the same information. A form generated by a PHP
process can submit to a Django view with no issue, and vice versa.
