In the code below, we have a simple array of contact names. We want to use the $contacts array to fill in the hardcoded list of names an email addresses. To hold the email as well as the name for each contact, we need a multidimensional array, meaning each person in the contact list will have their own array. The first step is to make each person their own single item ASSOCIATIVE array, using 'name' as the key for these internal arrays.
<?php
//edit this array
$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');
echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li>Alena Holligan : alena.holligan@teamtreehouse.com</li>\n";
echo "<li>Dave McFarland : dave.mcfarland@teamtreehouse.com</li>\n";
echo "<li>Treasure Porth : treasure.porth@teamtreehouse.com</li>\n";
echo "<li>Andrew Chalkley : andrew.chalkley@teamtreehouse.com</li>\n";
echo "</ul>\n";

Treehouse Moderator 91,253 PointsHi Parker,
The big clue is in the comment that Alena left in. The syntax is the name of the array and it's array index.
But to replace the string and get it to display in the right way you need to concatenate the string which means to add one string to another.
Add the new strings like this
<?php
echo "<li> . $contacts[0] . " " . : alena.holligan@teamtreehouse.com</li>\n";
?>
I've added another empty string just in case it was needed but you may need to experiment further. :-)
