I can't catch how to get emails from contacts array

The 3rd task of Challenge makes me really discouraged.

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

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

Hello Violetta,

Based on code you provided:

  • You have to declare an array before you gonna try to add items to it, like that:
<?php
$contacts = array(); // or
$contacts = []; // these can be used interchangeably but first one is more common
  • After you have some items in your array, you could use foreach instruction to echo all addresses within your arrays like that:
<?php
foreach($contacts as $contact): echo $contact['name'].": ".$contact['email']; endforeach;

Hope it helps,

Konrad
