why this not work in multi dimes. challenge ?

Which part are you having trouble passing?

Challenge 2 of 3?

In this challenge they want an array key of 'email' you named it 'Email', the solution is a simple as renaming all of the 'Email' keys to 'email'.

For Challenge 3 of 3 you have to use array access to get the information replacing the hardcoded string. For example:

<?php
echo "<li>{$contacts[0]['name']} : {$contacts[0]['email']}</li>\n"; // would replace
echo "<li>Alena Holligan : alena.holligan@teamtreehouse.com</li>\n"; // this

$contacts[] = [ 'name' => 'Alena Holligan', 'email' => 'alena.holligan@teamtreehouse.com', ] $contacts[] = [ 'name' => 'Dave McFarland', 'email' => 'dave.mcfarland@teamtreehouse.com', ] $contacts[] = [ array('name'=>'Treasure Porth', 'email'=>'treasure.porth@teamtreehouse.com', ] $contacts[] = [ 'name' => 'Andrew Chalkley', 'email' => 'andrew.chalkley@teamtreehouse.com', ] echo "<ul>\n";

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

Each 'value' in the arrays need to be given a 'key'.

In your code you are adding the email addresses into the same string as the names.

<?php
var_dump($contacts[$name1]) // Would return "Alena Holligan,alena.holligan@teamtreehouse.com"

There isn't really an easy way to grab the name or email values this way.

What you want to do is break up each piece of information (name and email) like this:

<?php
$contacts = array(
    $name1 => array(
        'name' => 'Alena Holligan',
        'email' => 'alena.holligan@teamtreehouse.com'
    )
);

This way you could access the values like so:

<?php
echo $contacts[$name1]['name'] // Would echo 'Alena Hooligan'
echo $contacts[$name1]['email'] // Would echo 'alena.hooligan@teamtreehouse.com'

What is wrong with this its work in my wamp server !

<?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 $contacts[0]['name'];
echo "<ul>\n";
//$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";
?>

No the first challenge add each person to array i created it as above work in my computer but not work in challenge

This will do the trick.

$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')
            );
