STAGE 4 CHALLENGE TASK 4 OF 7

The second echo statement displays the number of letters, but right now it always shows 2. Change that second echo statement to display the number of elements in the array.

letters.php 
<?php



echo "My favorite ";

echo " letters are these: ";
$letters = array ("D", "G", "L");
 echo $letters [D]. "\n" . $letters [G] . "\n" . $letters [L]; 
echo "AB";
echo ".";

?>

Hi there,

It seems that the challenge wants us to echo out "My favorite 3 letters are these: AB." You'll get to fix the logic of that sentence later on, but for now, what you want to do with this step is echo out the count of the letters array (in other words, how many values are in the letters array.)

<?php

$letters = array("D","G","L");

echo "My favorite ";
echo count($letters);
echo " letters are these: ";
echo "AB";
echo ".";

?>

Hope this helps.
