Why isn't this working?

Hi,

I am following the instructions. Am I missing something?

Thanks-

letters.php 
<?php

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

echo "My favorite ";
echo "3";
foreach {
echo " letters are these: ";
echo "AB";
}
echo ".";

?>

As far as I remember, this exercise asks you to replace the number 3 for the array count and the letters AB with the letter that are inside the array.

The answer would be, replace the 3 for:

echo count($letters)

And replace AB for:

foreach($letters as $letter){
   echo $letter;
}

Is not correct!

Your loop is not getting any information from the array, therefore it doesn't really know what to do! :P

<?PHP
$letters = array("a", "B", "c");

foreach($letters as $letter) {
    echo $letter . ' <br />';
}
?>
