I am currently learning PHP and I came across the `parse_str()` function. I've been reading the documentation but I'm still having some trouble fully grasping how it works.
From what I understand, the `parse_str()` function is used to parse a query string into variables. It seems to take a string as input and converts it into an array that contains variables as keys and their corresponding values. However, I'm not quite sure how it handles different scenarios or what the output would look like for a given input.
Could someone please provide a clear example of how the `parse_str()` function works? It would be great if you could explain each step of the process and provide some personal insight or tips on when and how to best use it.
I appreciate any help you can provide. Thank you in advance!
