Parameters and arguments are important ideas in programming, especially when we talk about functions.

Parameters are like labels you put in a function to show what kind of information it needs. They help define how many pieces of information the function will take and what types those pieces should be. For example, in the function function add($a, $b), the $a and$b are parameters.

Arguments, on the other hand, are the actual pieces of information you give to a function when you use it. They match up with the parameters in the function. So, if you call the function like this: add(5, 3), the numbers 5 and 3 are the arguments.

Here’s a simple breakdown of the differences:

1. What They Mean:

   • Parameters tell you what inputs a function needs.
   • Arguments are the actual values you provide to those parameters when you run the function.

2. Where They Live:

   • Parameters are found when you write the function.
   • Arguments are used when you call or run the function.

3. Matching Up:

   • Parameters describe what types of information are expected (like whole numbers or words).
   • Arguments need to match the types listed in the parameters for the function to work properly.

4. Where They Come From:

   • Parameters can only be used inside the function.
   • Arguments can come from anywhere in the code that can access the function.

Knowing these differences is really important for programming. It helps you understand how to create functions and how to use them correctly!
