this is worded badly

What are they asking here?

index.php 
<?php
//edit this array
$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');
$contacts['Alena Holligan'] = ['name' => 'Alena Holligan', 'email' => 'alena.holligan@teamtreehouse.com'];
$contacts['Dave McFarland'] = ['name' => 'Dave McFarland', 'email' => 'dave.mcfarland@teamtreehouse.com'];
$contacts['Treasure Porth'] = ['name' => 'Alena Holligan', 'email' => 'treasure.porth@teamtreehouse.com'];
$contacts['Andrew Chalkley'] = ['name' => 'Alena Holligan', 'email' => 'andrew.chalkley@teamtreehouse.com'];


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";

Every item in $contacts array should have type of array, so each of them needs to be enclosed with squared parenthesis. Step 1 of 3

<?php
//edit this array
$contacts = array(['name' => 'Alena Holligan'], ['name' => 'Dave McFarland'], ['name' => 'Treasure Porth'], ['name' => '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";

Step 2 of 3

<?php
//edit this array
$contacts = array(['name' => 'Alena Holligan', 'email' => 'alena.holligan@teamtreehouse.com'],
                  ['name' => 'Dave McFarland', 'email' => 'dave.mcfarland@teamtreehouse.com'],
                  ['name' => 'Treasure Porth', 'email' => 'treasure.porth@teamtreehouse.com'],
                  ['name' => 'Andrew Chalkley', 'email' => 'andrew.chalkley@teamtreehouse.com']);

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";

Step 3 of 3

<?php
//edit this array
$contacts = array(['name' => 'Alena Holligan', 'email' => 'alena.holligan@teamtreehouse.com'],
                  ['name' => 'Dave McFarland', 'email' => 'dave.mcfarland@teamtreehouse.com'],
                  ['name' => 'Treasure Porth', 'email' => 'treasure.porth@teamtreehouse.com'],
                  ['name' => 'Andrew Chalkley', 'email' => 'andrew.chalkley@teamtreehouse.com']);

echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li>".$contacts[0]['name']." : ".$contacts[0]['email']."</li>\n";
echo "<li>".$contacts[1]['name']." : ".$contacts[1]['email']."</li>\n";
echo "<li>".$contacts[2]['name']." : ".$contacts[2]['email']."</li>\n";
echo "<li>".$contacts[3]['name']." : ".$contacts[3]['email']."</li>\n";
echo "</ul>\n";
