Why isn't this accepted output?

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

The output your code generates has to be identical to the one that was originally in the challenge. The original text included <li> tags around the text being echoed, and there was a space both before and after the colon that separates the name and email.

You also have a var_dump call which the task did not ask for which generates output.

If you add the <li> start and end tags, fix the spacing around the colon and remove the var_dump like this:

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

Thanks @andren, really helped a lot :) I was scratching my head over this for ages, turned out that the extra var_dump() was the problem!

try this

<?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"; //$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'] .
