Why it is not working ?

Why is it writing that the output is not correct ?

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";
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";

It might be because you're escaping lines in your output HTML list where they're not needed.

Lists have default formatting so if you're trying to output each list item on as new line they will do this automatically. 

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