How I create for every person a array?

Please look my code. I don't unterstand why the code not exactly run?

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

Hi Phil,

The names inside the Arrays are keys so you need to do foreach loop on them. I have added example below. Hope this makes sense.

Example 

$numbers = array(
    array(
        'one' => 1,
        'two' => 2
   ), 
    array(
        'three' => 3,
        'four' => 4
   ) 
);

for($n = 0; $n < count($numbers); $n++){
    foreach($number[$n] as $key => $val){
        echo $key. ' ' .$val.'<br>';
    }
}
