PHP arrays, multidimensional arrays,challenge task 1 of 3 .. i am not sure what i would have to do exactly

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

//$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley'); echo $contacts[0]['name']." : ". $contacts[0]['email']; echo $contacts[1]['name']." : ". $contacts[1]['email']; echo $contacts[2]['name']." : ". $contacts[2]['email']; echo $contacts[3]['name']." : ". $contacts[3]['email'];

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

//$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');
echo  $contacts[0]['name']." : ". $contacts[0]['email'];
echo  $contacts[1]['name']." : ". $contacts[1]['email'];
echo  $contacts[2]['name']." : ". $contacts[2]['email'];
echo  $contacts[3]['name']." : ". $contacts[3]['email'];

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";

Hi there,

In your code you're using the same array $contacts and replacing it with each line. What you need to do is create a multidimensional array. Arrays within and array...

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

Can you set it to answered then :)
