Change the second echo statement to use a function to display the number of elements in $letters.

The second echo statement was set up to display the number of letters, but it always showed "2", and we have additional elements in $letters now. Change the second echo statement to use a function to display the number of elements in $letters.

index.php
<?php
$letters = array ('A','C','M','E');

echo "Today's challenge is brought to you by the ";
echo "4";
echo " letters: ";
echo "AC";
echo ".";

Hi Simingaye,

This part of the challenge is trying to get you to use the count() function rather than echoing the string "4"

If you pass the letters array into the count function it will return how many items are in that array.

All you have to do then is replace the literal string "4" with a call to the count function.

echo count($letters);

echo "AC";
echo ".";
