What is it asking me to do?

It says it wants...

The first step is to make each person their own single item ASSOCIATIVE array, using 'name' as the key for these internal arrays.

index.php 
<?php
//edit this array
  $contacts[0] = [
  "name" => "Alena Holligan",
  ]
  $contacts[1] = [
  "name" => "Dave McFarland",
  ]
  $contacts[2] = [
  "name" => "Treasure Porth",
  ]
  $contacts[3] = [
  "name" => "Andrew Chalkey",
  ]

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";*/

First step:

$contacts = array(
  ['name' => 'Alena Holligan'], 
  ['name' => 'Dave McFarland'], 
  ['name' => 'Treasure Porth'], 
  ['name' => 'Andrew Chalkley']
);

Second step:

$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']
);

And the last step:

echo "<ul>\n";
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";
