I don't know why I'm getting stuck with these.

Courses Plus Student 9,647 Pointsyour code should match this:
<?php
$letters = array("D", "G", "L");
echo "My favorite ";
echo count($letters);
echo " letters are these: ";
foreach($letters as $letter) {
echo $letter;
}
echo ".";
?>

887 PointsThe fourth echo statement, the one inside the foreach loop, should display my favorite letters from the array INSTEAD of AB. Remove the static piece of text from that fourth echo statement, changing it instead to display the value for the array element under consideration inside the foreach loop.
<?php
$letters = array("D", "G", "L");
echo "My favorite ";
echo count($letters);
echo " letters are these: ";
foreach($letters as $letter){
echo $letter;
echo "AB";
}
echo ".";
?>

Courses Plus Student 9,647 Pointsyou need to remove the echo "AB"; statement because it's static text.
