Can some one please help me?

May be my code is wrong or I am not able to grasp the question.

```$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') );

Here is my code, but it doesn't  work.

Thanks for the response.

```index.php
<?php
//edit this array

//$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');
$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 Piyush,

the first part of you answer is correct as you have created multidimensional array. The second part talks about ASSOCIATIVE array, using 'name' as the key. Like:

<?php
array( 'name' => 'Alena Holligan' )

I didn't get what you mean by this? I didn't get how to form this kind of array.

Hi, I could have been more descriptive. The first part of the task is good, but the second one should look like this:

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

so when you will want to add another key, like email, you just add a new key with a value:

<?php
$contacts = array(
                  array( name => 'Alena Holligan', email => 'alena.holligan@teamtreehouse.com' ), 
etc

This one is not working.

$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') );

sorry, I forgot to wrap keys with ' so it should be 'name' and 'email'...
