display count

I don't know how to get a count of elements in the array. She didn't teach that, did she?

index.php
<?php
$letters = array();
$letters[] = "A";
$letters[] = "C";
$letters[] = "M";
$letters[] = "E";


echo "Today's challenge is brought to you by the ";
echo "2";
echo " letters: ";
echo "AC";
echo ".";

?>

This can be done with the count function. Check out the documentation here. You could also use sizeof which is an alias for count, its documentation is here.

<?php
$letters = ['A', 'C', 'M', 'E'];


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

?>
