PHP PHP Arrays and Control Structures PHP Arrays Multidimensional Arrays

PHP arrays and control structures

in the code below ,we have a simple array of contact .we want to use the $contacts array to fill in the hardcoded list of names and email addresses. To hold BOTH the email as well as the name for each contact ,we need a multidimensional array. Each person in the contact list will have their own inner array .The inner array will be an associative array of name and email. The first step is to add a second inner array to the $contacts array instead of each value being a string containing a name,each value should be an ASSOCIATIVE array.Use the string 'name' as the key and their actual name as the value for these internal arrays.

index.php 
<?php
//edit this array
$contacts = array(
  [
    'name'=>'Alena Holligan',
    'email'=> 'alena.holligan@teamtreehouse.com',
    ],
      [
        'name'=> 'Dave McFarland',
        'email'=> 'dave.mcfarland@teamtreehouse.com',
        ],
  [
    'name'=> 'Treasure Porth',
    'email'=> 'treasure.porth@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";

Hello Tawanda!

i'm not 100% sure so please correct me if and when i'm wrong but try this code below. Keep in mind that you have to leave the first $contacts array as it is and create different arrays specifying their keys ( the square brakets numbers)

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

$contacts[0] = [
  'name' => 'Alena Holligan',
  'email' => 'alena.holligan@teamtreehouse.com'
];

$contacts[1] = [
  'name' => 'Dave McFarland',
  'email' => 'dave.mcfarland@teamtreehouse.com'
];

$contacts[2] = [
  'name' => 'Treasure Porth',
  'email' => 'treasure.porth@teamtreehouse.com'
];

$contacts[3] = [
  '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";
