The original code was hard-coded to echo the letters "AC" instead of the contents of the $letters array.

The original code was hard-coded to echo the letters "AC" instead of the contents of the $letters array. Replace the fourth echo statement with a foreach loop that prints each letter in the array.

index.php 
<?php



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

$letters[]= A;
  $letters[]=C;
$letters[]=M;
$letters[]=E;

The foreach display is used to iterate over an array, and while doing so assigning the value of each element of that array to a new variable that you define inside the foreach loop. This temporary variable only exists during the iteration period, but gives you a means of accessing each value in the array.

The PHP Manual: foreach provides a helpful blueprint and examples which are similar to the exercise in this challenge. 

<?php
foreach($array as $value)
{
  // do something with $value
}
