How can the use of func_num_args() and func_get_arg() in PHP functions impact performance?

Using func_num_args() and func_get_arg() in PHP functions can impact performance because these functions are slower compared to directly accessing function arguments. To improve performance, it is recommended to use named arguments or pass arguments as an array instead. 

function myFunction($args) {
    $arg1 = $args[0];
    $arg2 = $args[1];
    
    // Rest of the function logic
}

// Call the function with arguments passed as an array
myFunction([$value1, $value2]);
