How can the use of func_get_args and func_num_args help in dealing with a variable number of variables in PHP methods?

When dealing with a variable number of variables in PHP methods, the functions `func_get_args` and `func_num_args` can be used to handle the parameters passed to the method. `func_get_args` returns an array of all the arguments passed to the method, while `func_num_args` returns the number of arguments passed. These functions allow for flexibility in handling different numbers of arguments without explicitly defining them in the method signature. 

function exampleMethod() {
    $args = func_get_args();
    $numArgs = func_num_args();

    for ($i = 0; $i < $numArgs; $i++) {
        echo "Argument $i: " . $args[$i] . "<br>";
    }
}

exampleMethod("Hello", "World", 123);
