While this works in many programming languages, you might struggle to retrieve those values properly in PHP. So, how can you achieve this seamlessly?

The Solution: Utilizing PHP Arrays

The key to passing and handling multiple values in PHP is to use arrays. By appending [] to the parameter name, you tell PHP that you're sending an array of values. Here's how you can structure your URL:
