Not sure what function to use...

The second echo statement was set up to display the number of letters, but it always showed "2", and we have additional elements in $letters now. Change the second echo statement to use a function to display the number of elements in $letters.

This is what my code looks like. <?php $letters = array("A", "C", "M", "E");

echo "Today's challenge is brought to you by the "; function display() { return $letters[]; } echo " letters: "; echo $letters; echo ".";

?>

PHP has a function to get the length of an array. If the array name is $letters, then count($letters) will return the length.

but cant i use the sizeof method?

for example 

<?php 

$letters = array("A", "C", "M", "E");

echo sizeof($letters);

?>

This also works and returns a value of 4 in my IDE but doesn't work in workspaces. Any idea what might be causing this not to work in workspace?

Hey Daniel,

As Jcorum stated, use the count() function to return the length. Below is a working example:

<?php

$letters = array('A', 'C', 'M', 'E');

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

?>
