count() function

What do I need to do here? It tells me to show the amount of letters. How do you need to do that?


$letters = array("A","C","M","E");
echo "Today's challenge is brought to you by the ";
echo $letters;
echo " letters: ";
echo "AC";
echo ".";

Id' suggest something like this:

$count = count($letters);

echo $count;

The $count variable will return the amount of items in the array $letters.

echo count($letters);
