Here we go "stuck again":)

The code gives the right display, I guess .

For the experts out there: What could be wrong?

Thanks for the help.

//edit this array
$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');
$contacts = array
  array('Alena Holligan','alena.holligan@teamtreehouse.com'),
  array('Dave McFarland','dave.mcfarland@teamtreehouse.com'),
  array('Treasure Porth','treasure.porth@teamtreehouse.com'),
  array('Andrew Chalkley','andrew.chalkley@teamtreehouse.com')
echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li>" . $contacts[0][0] . " :" . $contacts[0][1]."</li>\n";
echo "<li>".$contacts[1][0] . " :" . $contacts[1][1]."</li>\n";
echo "<li>".$contacts[2][0] . " :" . $contacts[2][1]."</li>\n";
echo "<li>".$contacts[3][0] . " :" . $contacts[3][1]."</li>\n";
echo "</ul>\n";

I do not understand: where are you stuck? I put your code on my computer and it displays me a list of name and e-mail. Do you want to optimize your code?

Cheers. Thomas.

Hi! That is what I don't understand. In the lesson it tells me to display a list of contacts and email of each individual where each individual has its own array. But I get a message telling me that the output is not correct. Perhaps I didn't understand the task properly. That is what I want a help with.

Sorry for not being clear. I am just trying to get use to it.

Thank you very much.

Ok, understood (I looked at the challenge ^^).

So, you have to set 'name' as the key value of your multidimensional array. The syntax for this is quite simple:

$yourArray = [
    'name' => 'value'

You can go on php.net to find a great peace of ressources :) => multi array

And the solution of your first step:

$contacts = array(
  ['name' => 'Alena Holligan'], 
  ['name' => 'Dave McFarland'], 
  ['name' => 'Treasure Porth'], 
  ['name' => 'Andrew Chalkley']

Shame on me. You are right, it is quite simple and embarrassing. Unfortunately it seems to be just the beginning of a pile of simple mistakes.

Thank you for your passions and help.
