What Are Function Parameters and How Do I Use Them?

You give values to the parameters simply by calling the function with arguments like so: `example_name(value1, value2);`.

It can be a bit tricky at first! Parameters are placeholders you define when creating a function, while arguments are the actual values you pass in when you invoke the function. For instance, in `function myFunction($param1, $param2){ return $param1 + $param2; }`, the parameters are `$param1` and `$param2`. When you call it with `myFunction('hello', 'world')`, the arguments are 'hello' and 'world', which results in 'hello world'. This lets you reuse the same function with different values.

Parameters in a function receive the arguments you send when calling that function. So, if you have `example_name("abc", 123)`, then `$param` will be "abc" and `$arg` will be 123 when the function runs.

Yes, it looks like you're working with PHP! The `$` indicates variables, and the parameters listed in parentheses are what the function can accept. When you call the function, you're passing actual values, known as arguments. For example, `example_name(1, 1)` passes integers to your function.

To use a function with parameters, you first need to call it by passing the values. For example, if you have a function `public function example_name($param, $arg)`, you can call it like this: `example_name('hello', 'world');`. This would return 'hello world' since it outputs `$param` and `$arg` together with a space in between.
