Error- " Bummer! I do not see the required output. You should not be modifying the output at this point."

I do not see where I am going wrong. Multidimensional arrays. Help!!!

index.php 
<?php
//edit this array
$contacts = [
  $contacts[0] = ['name' => 'Alena Holligan', 'email' => 'alena.holligan@teamtreehouse.com'],
  $contacts[1] = ['name' => 'Dave McFarland', 'email' => 'dave.mcfarland@teamtreehouse.com'],
  $contacts[2] = ['name' => 'Treasure Porth', 'email' => 'treasure.porth@teamtreehouse.com'],
  $contacts[3] = ['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";

Challenges are extremely picky about text output, it usually has to match the expected output exactly as specified.

In your case the issue is that on this line:

echo "<li>" . $contacts[1]['name'] . ": " . $contacts[1]['email'] . "</li>\n";

You are missing a space before the : inside the string

And on this line:

echo "<li>" . $contacts[2]['name'] . "  : " . $contacts[2]['email'] . "</li>\n";

You have two spaces before the : instead of one.

If you fix those spacing issues like this:

<?php
//edit this array
$contacts = [
  $contacts[0] = ['name' => 'Alena Holligan', 'email' => 'alena.holligan@teamtreehouse.com'],
  $contacts[1] = ['name' => 'Dave McFarland', 'email' => 'dave.mcfarland@teamtreehouse.com'],
  $contacts[2] = ['name' => 'Treasure Porth', 'email' => 'treasure.porth@teamtreehouse.com'],
  $contacts[3] = ['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";

Then your code will pass.
