why it gives me error

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";

You're pretty close there, but you cannot output an associative array directly within a string. So you can use concatenation to join the variables with literal strings:

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