How does the use of __FUNCTION__ and func_get_args() in PHP help in passing arguments to functions without the need for a "self()" function?

Using __FUNCTION__ and func_get_args() in PHP allows us to pass arguments to functions dynamically without the need for explicitly defining the arguments in the function declaration. This is particularly useful when we want a function to accept a variable number of arguments without having to modify the function signature each time. 

function myFunction() {
    $args = func_get_args();
    $functionName = __FUNCTION__;
    
    // Use $args array to access the passed arguments dynamically
    foreach ($args as $arg) {
        echo "Argument passed to function $functionName: $arg<br>";
    }
}

myFunction('arg1', 'arg2', 'arg3');
