Cannot get past this exercise

How do I echo a value from an associative array?

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'
], ['name' => 'Andrew Chalkley', 'email' => 'andrew.chalkley@teamtreehouse.com']);

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

You don't need the printf() function. The echo statements are already there for you in place.

What the challenge is asking you to do is replace the hard coded values that represent what is in the array with the values according to the array index, but if you put it in a string the PHP engine will read that as text.

For example,

Replace the lines like this.

<?php
echo "<li>print_r($contacts[0]['name']) : print_r($contacts[0]['email'])</li>\n";

To look more like this

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

Good luck, and shout again if you're still stuck. :)
