Please show me how to do it with steps.

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

Hi mahmoud gamie,

Let's begin. So the first task asks us The first step is to make each person their own single item ASSOCIATIVE array, using 'name' as the key for these internal arrays

<?php
//edit this array
$contacts = array(
  // Added assiociative array with key 'name'
  array( 'name' => 'Alena Holligan'),
  array('name' => 'Dave McFarland'), 
  array('name' => 'Treasure Porth'), 
  array('name' => 'Andrew Chalkley')
);
?>

Task 2 asks us 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

<?php
$contacts = array(
  // Added assiociative array with key 'name'
  // Added  second element with the key 'email' to the internal array of each person
  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')
);
?>

Task 3 asks us Replace the hard coded values in the output with the name and email values from the contacts array.

<?php
$contacts = array(
  // Added assiociative array with key 'name'
  // Added  second element with the key 'email' to the internal array of each person
  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')
);
// replaced hard coded values in the output with the name and email values from the contacts array
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";
?>

I hope it helps:)
