What is the correct way to pass variables within functions in PHP?

When passing variables within functions in PHP, you can simply pass them as arguments when calling the function. This allows you to use the values of the variables within the function without affecting the original variables outside of it. Make sure to define the function with parameters that will receive the values of the variables being passed. 

// Define a function that takes two variables as arguments
function addNumbers($num1, $num2) {
    $sum = $num1 + $num2;
    return $sum;
}

// Call the function and pass variables as arguments
$result = addNumbers(5, 3);
echo $result; // Output: 8
