How to echo data from multidimensional arrays. How do I get the echo commands to display name and email

Question

<?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"; //$contacts[0] will return 'Alena Holligan' in our simple array of names. echo "<li$contacts[0]</li>\n"; echo "<li>$contacts[1]</li>\n"; echo "<li>$contacts[2]</li>\n"; echo "<li>$contacts[3]</li>\n"; echo "</ul>\n";

index.php

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

Since you have an array where each array element is another array (hence - multi dimensional), you'll need to provide index entries for each level of the array.

The $contacts Array in your example has 4 elements and they are numerically indexed starting at zero so Alena is index 0 and Dave is index 1 and so on...

At each index (0 thru 3) you have another array. An Associative array since they have named keys.

So, $contacts at index zero has a value for name and a value for email. You need to provide both indexes as per the example below:

<?php
// below is the second array in the $contacts array - Dave McFarland - since the index is 1
echo "<li>" . $contacts[1]['name'] .  " the email is " . $contacts[1]['email'] ."<li>\n";

Test your code in your workspace or local environment.

Hope that helps
