PHP PHP Arrays and Control Structures PHP Arrays Multidimensional Arrays

I need help about this "Multidimensional Arrays" task.

This is where i got, code is working on the my own editor but something is wrong according to the exercise.

"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 the email as well as the name for each contact, we need a multidimensional array, meaning each person in the contact list will have their own array. The first step is to make each person their own single item ASSOCIATIVE array. Use the string 'name' as the key and their actual name as the value for these internal arrays."

"Bummer! Each person in the contact list should have their own internal array. Use another "array()" for each person."

index.php
<?php
//edit this array
$contacts[] = ['Alena' => 'Alena Holligan ',
                  'Dave' => 'Dave McFarland ',
                  'Treasure' =>'Treasure Porth ', 
                  'Andrew' => 'Andrew Chalkley '
];

$contacts[] = ['Alena' => ' alena.holligan@teamtreehouse.com',
                  'Dave' => ' dave.mcfarland@teamtreehouse.com',
                  'Treasure' =>' treasure.porth@teamtreehouse.com', 
                  'Andrew' => ' andrew.chalkley@teamtreehouse.com'
];

echo "<ul>\n";

//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li>" . $contacts[0]['Alena'] . ":" . $contacts[1]['Alena'] . "</li>\n";
echo "<li>" . $contacts[0]['Dave'] . ":" . $contacts[1]['Dave'] . "</li>\n";
echo "<li>" . $contacts[0]['Treasure'] . ":" . $contacts[1]['Treasure'] . "</li>\n";
echo "<li>" . $contacts[0]['Andrew'] . ":" . $contacts[1]['Andrew'] . "</li>\n";
echo "</ul>\n";

"Bummer! Each person in the contact list should have their own internal array. Use another "array()" for each person."

There are many ways of getting to the solution. But this below is one way:

<?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'
        )
  );

echo "<ul>\n";
echo "<li>" .$contacts[0]['name'] . ': ' . $contacts[0]['email']. "</li>\n";
echo "<li>" .$contacts[1]['name'] . ': ' . $contacts[1]['email']. "</li>\n";
echo "<li>" .$contacts[2]['name'] . ': ' . $contacts[2]['email']. "</li>\n";
echo "<li>" .$contacts[3]['name'] . ': ' . $contacts[3]['email']. "</li>\n";
echo "</ul>\n";

?>

the task was this

"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 the email as well as the name for each contact, we need a multidimensional array, meaning each person in the contact list will have their own array.
