Add a second element with the key 'email' to the internal array of each person. You'll find the correct email for each person in the hard coded output. Where am i getting it wrong--may someone help please.

index.php 
<?php
//edit this array
$contacts = array(
                                array('name'=>'Alena Holligan'
                        array_push($contacts,'email'=>'alena.holligan@teamtreehouse.com')),

                    array('name'=>'Dave McFarland'
                        array_push($contacts,'email'=>'dave.mcfarland@teamtreehouse.com')),

                  array('name'=>'Treasure Porth'
                         array_push($contacts,'email'=>'treasure.porth@teamtreehouse.com')),

                  array('name'=>'Andrew Chalkley'
                          array_push($contacts,'email'=>'andrew.chalkley@teamtreehouse.com.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";

Hey Abson - Your array should look like this:

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

Hope that helps.

Cheers,

Ben

Hello Abson,

You can define arrays in two ways. Depending on preference and PHP version:

1) $contacts = array();
2) $contacts = [];

The second one is supported as of PHP 5.4

You can't put a function (array_push) inside an array definition. You are using an array that contains associative arrays. The outer array will automatically use keys like 0, 1, 2, ... In the associative arrays you define the key (and value) yourself. If you have to add the key 'email' to the definition, just add it like the key 'name'. Items in an array are separated with a comma.

$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.com'
   )
);
