is there a place to see the answers for each task?

unfortunately, the "bummer" suggestion just isn't helpful enough in this instance. I don't think that my code is semantically in error, but I'm clearly trying to do the wrong thing and comparing to the correct answer would be helpful.

index.php 
<?php
//edit this array
$alena = array(
  'name' => 'Alena Holligan',
 );
$dave = array (
  'name' => 'Dave McFarland',
);
$treasure = array(
  'name' => 'Treasure Porth',
);
$andrew = array(
  'name' => 'Andrew Chalkley',
);
/*$contact[] = [
  'name' => 'Alena Holligan',
  'email' => 'alena.holligan@teamtreehouse.com',
];
$contact[] = [
  'name' => 'Dave McFarland',
  'email' => 'dave.mcfarland@teamtreehouse.com',
 ];
$contact[] = [
  'name' => 'Treasure Porth',
  'email' => 'treasure.porth@teamtreehouse.com',
 ];
$contact[] = [
  'name' => 'Andrew Chalkley',
  'email' => 'andrew.chalkley@teamtreehouse.com',
];*/
echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li>Alena Holligan : alena.holligan@teamtreehouse.com</li>\n";
echo "<li>Dave McFarland : dave.mcfarland@teamtreehouse.com</li>\n";
echo "<li>Treasure Porth : treasure.porth@teamtreehouse.com</li>\n";
echo "<li>Andrew Chalkley : andrew.chalkley@teamtreehouse.com</li>\n";
echo "</ul>\n";

Sadly there is not. You can usually find old forum posts for the challenge by searching for the challenge name plus the word Treehouse on Google though, which will often contain an example of how to solve the challenge.

As for your code, your commented out attempt is actually fine, you have just typed the wrong variable name, the array is supposed to be called contacts not contact.

If you fix that typo like this:

<?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>Alena Holligan : alena.holligan@teamtreehouse.com</li>\n";
echo "<li>Dave McFarland : dave.mcfarland@teamtreehouse.com</li>\n";
echo "<li>Treasure Porth : treasure.porth@teamtreehouse.com</li>\n";
echo "<li>Andrew Chalkley : andrew.chalkley@teamtreehouse.com</li>\n";
echo "</ul>\n";

Then you will be able to pass the first task.
