What are the potential pitfalls of using functions with the same name but different parameters in PHP?

When using functions with the same name but different parameters in PHP, you run the risk of encountering conflicts and unexpected behavior. To avoid this, you can use function overloading by checking the number of parameters passed to the function and implementing different behavior based on the parameter count. 

function myFunction($param1, $param2 = null) {
    if (func_num_args() == 1) {
        // Handle function behavior with one parameter
    } else {
        // Handle function behavior with two parameters
    }
}
