Can someone help me? (PHP)

Hello, I can't solve this. Can some one give me the answer and why this isn't right. The question is: In the code below, we have a simple array of contact names. We want to use the $contacts array to fill in the hardcoded list of names and email addresses. To hold BOTH the email as well as the name for each contact, we need a multidimensional array. Each person in the contact list will have their own inner array. The inner array will be an associative array of name and email.

The first step is to add a second inner array to the $contacts array. Instead of each value being a string containing a name, each value should be an ASSOCIATIVE array. Use the string 'name' as the key and their actual name as the value for these internal arrays.

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

I believe this is what they are looking for

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

Thxx, I see now where I did do something wrong. But I still got a problem I need to Replace the hard coded values in the output with the name and email values from the contacts array. I tought just var_dump it but that isn't correct. Can you help me?

Sure. You can access each contact using the follow syntax

<?php
echo "<li>" . $contacts[0]['name'] . " : " . $contacts[0]['email'] . "</li>\n";
