Hi! i really dont know where is my mistake here, as i did what is written in the task:

please redirect me to the right way and show me my mistakes.

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

$contacts[name] = [

      'Name' => 'Alena Holligan',
      'Email' => 'alena.holligan@teamtreehouse.com',
];

$contacts[name] = [

      'Name' => 'Dave McFarland',
      'Email' => 'dave.mcfarland@teamtreehouse.com',
];

$contacts[name] = [

      'Name' => 'Treasure Porth',
      'Email' => 'treasure.porth@teamtreehouse.com',
];

$contacts[name] = [

      'Name' => 'Andrew Chalkley',
      'Email' => '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";

btw it didnt work even with my first try that it was lik the following code:

      ```
                   $contacts[] = [

            'Name' => 'Alena Holligan',
            'Email' => 'alena.holligan@teamtreehouse.com',
        ];

        $contacts[] = [

            'Name' => 'Dave McFarland',
            'Email' => 'dave.mcfarland@teamtreehouse.com',
        ];

        $contacts[] = [

            'Name' => 'Treasure Porth',
            'Email' => 'treasure.porth@teamtreehouse.com',
        ];

        $contacts[] = [

            'Name' => 'Andrew Chalkley',
            'Email' => 'andrew.chalkley@teamtreehouse.com',
        ];

Breaking this down into the multiple steps:

Step 1. Convert each person to their own associate array with 'name' as the key

<?php
//edit this array
$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');
// Step 1. Convert each person to their own associate array with 'name' as the key
$contacts = array(
  array('name' => 'Alena Holligan'),
  array('name' => 'Dave McFarland'), 
  array('name' => 'Treasure Porth'),
  array('name' => 'Andrew Chalkley')
);

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";

Step 2. Add a second element with the key 'email' to the internal array of each person

<?php
//edit this array
$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');
// Step 2. Add a second element with the key 'email' to the internal array of each person
$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";
//$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";

Step 3: Replace the hard coded values in the output with the name and email values from the contacts array.

<?php
//edit this array
$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');
// 3. Replace the hard coded values in the output with the name and email values from the contacts 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";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
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";

Thanks to this question and the answer provided, I was able to get past the step 3. I didn't think of concatenating them together :O
