PHP PHP Arrays and Control Structures PHP Arrays Multidimensional Arrays

arrays

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.

where did i go wrong with my code please help

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

You can add echo print_r($contacts); below your array to inspect what the array looks like. Then you can see the array printed out after a failed attempt by clicking preview

Your array looks like this: Array ( [0] => Array ( [name] => Andrew Chalkley ) ) 1

And it should look like this: Array ( [0] => Array ( [name] => Alena Holligan ) [1] => Array ( [name] => Dave McFarland ) [2] => Array ( [name] => Treasure Porth ) [3] => Array ( [name] => Andrew Chalkley ) ) 1

Solution below:

<?php
//edit this array
$contacts[] = array('name' => 'Alena Holligan');
$contacts[] = array('name' => 'Dave McFarland');
$contacts[] = array('name' => 'Treasure Porth');
$contacts[] = array('name' => 'Andrew Chalkley');

// This is a good way to inspect what your array looks like
echo print_r($contacts);
