I need to be shown how to use a funciton to return the number of items in an array and display that on my webpage.
<?php $letters = array("A", "C", "M", "E", ) ; echo "Today's challenge is brought to you by the "; echo $arrlength = count(&letters); echo " letters: "; echo "AC"; echo "."; ?>

You need to use the count() function.
Here is an example of the count() function.
<?php $cars=array("Volvo","BMW","Toyota"); echo count($cars); ?>
Hope this helps. Happy coding!
