How do you change the second echo statement to a function that displays the number of elements in an array?

<?php

$letters = array("A", "C", "M", "E");

echo "Todays challenge is "; echo "2"; echo "AC"; echo ".";

?>

index.php
<?php

$letters = array("A", "C", "M", "E");

echo "Today's challenge is brought to you by the ";
count($letters);
echo " letters: ";
echo "AC";
echo ".";

?>

Hi there! It's already set up for you. All you need to do is add the echo.

<?php

$letters = array("A", "C", "M", "E");

echo "Today's challenge is brought to you by the ";
echo count($letters);  /* add the echo here */
echo " letters: ";
echo "AC";
echo ".";

?>

Happy coding! :sparkles:
