The assignment description is vague. I don't understand what she wants me to do..

Hey!

Click on the assignment to see where I'm stuck. I just don't understand what she wants me to do. It's described so odd that I just can't understand what I need to do..

Can someone maybe explain what I need to do?

The description says:

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

so each name needs to get an array right? My guess:

$contacts = array('Alena' => array('name' => 'Alena', 'email' => 'Alena@hotmail.com') )

OR

$contacts = array('Alena' => 'Alena')

OR

$contacts['name'] = array('Alena', 'Erik'); $contact['email'] = array('Alena@hotmail.com', Erik@hotmail.com)

What do I need to use??

index.php 
<?php
//edit this array
$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');

$list = array($contacts);

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";

Hi Marco,

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. You can do it like this:

<?php
$contacts = array( 
  array( 'Alena Holligan' ), 
  array( 'Dave McFarland' ), 
  array( 'Treasure Porth' ), 
  array( 'Andrew Chalkley' )
);

then next part is to make each person their own single item ASSOCIATIVE array, using 'name' as the key for these internal arrays

<?php
$contacts = array( 
  array( 'name' => 'Alena Holligan' ), 
  array( 'name' => 'Dave McFarland' ), 
  array( 'name' => 'Treasure Porth' ), 
  array( 'name' => 'Andrew Chalkley' )
);

after that you can easily add key 'email' in the next task...
