arrays

I have tried to add an internal array but failed.Can someone please tell me what is wrong with this code

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

Hi, so your error is that they ask for an array and not a dictionary (array is where the key is an int, a dictionary is where the key is a string). So you have to remove the key. So the right solution would be the following. If you have any other question please ask.

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