As Henrik said, this is what you should have:

<?php
//edit this array
$contacts[] = [
  "name" => "Alena Holligan",
  "email" => "alena.holligan@teamtreehouse.com",
]; 
$contacts[] = [
  "name" => "Dave McFarland",
  "email" => "dave.mcfarland@teamtreehouse.com",
]; 
$contacts[] = [
  "name" => "Treasure Porth",
  "email" => "treasure.porth@teamtreehouse.com",
]; 
$contacts[] = [
  "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 should also note that there's no need for you to have two sets of PHP tags.
