Study the code below to answer the questions that follow: function processValues$()\{$

$result $=0$;

$$

$args $=$ func$\_$get$\_$args$()$; foreach$($$args as $arg$)\{$

if$(!$is$\_$numeric$($$arg$))$

$$

$result$++$;

$$

$\}$

$$

echo func$\_$num$\_$args$()$; echo $"$

$"$;

echo $result;

$$

$\}$

$$

$($a$)$ Explain what the function does in terms of its input, logic, and output?

$$

$($b$)$ What is the outcome when the function is invoked with the statement, processValues$()$;$?$

$$

$($c$)$ What is a similarity and a difference between the functions func$\_$get$\_$args$()$and func$\_$num$\_$args$()?$

$$

$($d$)$ What is the outcome when you invoke the function using the statement, processValues$(2,4,6)$;$?$

$$

$($e$)$ Write a line of PHP code that will invoke the function that will result in the following being displayed?

$$

$2$

$$

$2$

$$

$($f$)$ Rewrite the foreach statement using a for loop without changing its logic.
