I'm relatively new to PHP and I'm currently working on a project where I need to replace URL parameters with variables in PHP. I have seen examples of passing data through URLs using parameters, but I want to make it more clean and secure by using variables instead.
To give you some context, I have a website where users can search for products using different filters such as category, price range, and brand. Currently, when a user selects these filters, the URL looks something like this: `example.com/products?category=electronics&price=100-500&brand=apple`.
Instead of having these parameters in the URL, I want to pass them as variables within my PHP script. For example, I would like to have something like:
$category = "electronics";
$price = "100-500";
$brand = "apple";
I believe this approach will make my code more maintainable and also protect my application from potential security risks.
Can someone please guide me on how to achieve this in PHP? Any example or code snippets will be highly appreciated.
Thanks in advance!
