What's wrong here?

Not quite sure how I've coded this wrong. Additionally the error that comes up is that I shouldn't be modifying the code in the way that I was directed to in the question.

index.php 
<?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 have also done this to try to eliminate any possible syntax errors:

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

Hi there Graham, if you take a look at the preview, it's telling you the issue there

Notice: Array to string conversion in index.php on line 12 Notice: Array to string conversion in index.php on line 12 Array['name'] : Array['email']

Just make sure that your variables are surrounded by curly braces to fix this.

<?php
echo "<ul>\n";
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";

Alternatively, you can use string concatenation.

[Edit] How come my syntax highlighting isn't as neat?

*Edited markdown, you needed to add the opening php tag for syntax highlighting to work. -JG
