I can't meet the challenge!

Here's my code, and I just can't pass the callenge! What does it want me to do?

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'
  );

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";

Hi oliverchou

The challenge was very hard to understand in my opinion... But after playing around I got the final solution (you can figure out which one belongs to which objective :)).

It probably failed because of the output, as there was an issue converting the array to string.

<?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";

I solved this by concatenating the Associative Array to the echo like this.

echo "<li>". $contacts[0]['name'] .  " : " . $contacts[0]['email'] . "</li>\n";

However when I was looking for a way to explain why you have to concatenate the associative array. I found out that you can put curly braces {} around the associative array and it will interrupt the value of the associate array. 

echo "<li> {$contacts[0]['name']} : {$contacts[0]['email']} .</li>\n";

This blog post explains it better than I can. I am still learning php too.
