The code block below displays a list of two letters from the Latin alphabet using echo statements. Let's change this block of code to display 4 letters. We'll also modify it to use an array so that it's easier to modify the letters in the future.
Before the first echo statement, create an array called $letters. Give the array two elements, with values of "A" and "C"
<?php

echo "2";
echo " letters: ";
echo "AC";
echo ".";
?>
