Introducing arrays question

Question

Now let’s add another letter. Add a fourth element to the array with a value of “R” (my personal favorite). When you preview the code, notice that the count of letters increases and the new letter is added to the list automatically.
When i type in the code it fails on task 4, since i need to add a fourth value to pass it further. 
<?php $letters = array ("D","G","L","R");
echo "My favorite ";
echo "3";
echo " letters are these: ";
foreach ($letters as $letter){
echo $letter;
}
echo ".";
?>
What to do? =)

you must change the second echo statement to display the number of elements in the array.                                                                                              
echo "3"                                                                                    
you must change the "3". try to use a function that counts all elements in an array
