Echoing php array in html <li></li> tags

Got stacked on the 3d step. I assume there is something wrong with the brackets when trying to echo array in a html tag.

Would appreciate your help, thanx!

index.php 
<?php
//edit this array
$contact1 = array('name' => 'Alena Holligan', 'email' => 'alena.holligan@teamtreehouse.com');
$contact2 = array('name' => 'Dave McFarland', 'email' => 'dave.mcfarland@teamtreehouse.com');
$contact3 = array('name' => 'Treasure Porth', 'email' => 'treasure.porth@teamtreehouse.com');
$contact4 = array('name' => 'Andrew Chalkley', 'email' => 'andrew.chalkley@teamtreehouse.com');

$contacts = array($contact1,$contact2,$contact3,$contact4);

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

echo "</ul>\n";

You are very close. I have a sample below to help you.

<?php
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"; // Duplicate this incrementing by one for each contact
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";

Hey Corey, any idea why this is not accepted by as the right answer. The output seems to be OK to me

<?php
//edit this array
$contacts = array();
  $contacts[] = array ('name' => 'Alena Holligan', 'email' => 'alena.holligan@teamtreehouse.com');
  $contacts[] = array ('name' => 'Dave McFarland', 'email' => 'dave.mcfarland@teamtreehouse.com');
  $contacts[] = array ('name' => 'Treasure Porth', 'email' => 'treasure.porth@teamtreehouse.com');
  $contacts[] = array ('name' => 'Andrew Chalkley','email' => 'andrew.chalkley@teamtreehouse.com');


foreach ($contacts as $contact) {
  echo "<ul>\n<li>" . $contact['name'] . " : " . $contact['email'] . "</li></ul>\n";
}

Vladislav,

I believe this is a matter of the tests looking for a certain string or substring(s) in your code to verify that you have it right and not looking at the output. Your solution is significantly better because the same 3 lines (your foreach) would be an adequate solution no matter how large the contacts list grew.

Thank you Corey!

so {} : {} this is used to bring together several values of a massive?

I believe you can actually use variables inside of strings so long as you use the double quotation marks with the curly brackets being optional. I use them because it helps make sure that the variables I am including in the string more apparent.

This particular example isn't a good illustration of why I personally think it's important because accessing the array indexes and keys makes it stand out but if it was just $name and $email tucked into there I'm prone to missing it.
