How can the code be modified to ensure the counter variable is passed correctly in recursive PHP functions?

When passing the counter variable in recursive PHP functions, it is important to pass it as an argument in each recursive call to ensure that the correct value is maintained throughout the recursion. This can be achieved by including the counter variable as a parameter in the function definition and passing it along with other arguments in each recursive call.

function recursiveFunction($counter, $otherArgument) {
    // base case
    if ($counter == 0) {
        return;
    }
    
    // do something with the counter variable
    
    // recursive call with updated counter
    recursiveFunction($counter - 1, $otherArgument);
}

// initial call to the recursive function with the starting counter value
recursiveFunction(5, $otherArgument);
