Stuck in challenge 1 from PHP Arrays and Control Structures

Hi guys, I have problems with this exercise. I really don't understand what I have to do. Can you help with this one?

index.php
<?php
//edit this array
$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');

echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li>$contacts[0]"." : alena.holligan@teamtreehouse.com</li>\n";
echo "<li>$contacts[1]"." : dave.mcfarland@teamtreehouse.com</li>\n";
echo "<li>$contacts[2]"." : treasure.porth@teamtreehouse.com</li>\n";
echo "<li>$contacts[3]"." : andrew.chalkley@teamtreehouse.com</li>\n";
echo "</ul>\n";

I also modified the $contacts array, but still did not get it right. The example above I took it from another example in the forum cause I don't understand what I need to do.

Thanks for help

Well, saw the answer on another post in the forum. I could not understand the exercise and what I had to do.

But:

  1. Change the first array, create an array for each person with 2 keys: name and email
  2. Change the name and email from the list with values from arrays.

Can anybody please tell me where I'm going wrong? I thought I had it covered but this comes up with the error message:

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

Thanks in advance

<?php
//edit this array
//$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');

$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> $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";

Hi Anne,

I think the second part is wrong: echo "<li>".$contacts[0]['name'].": ".$contacts[0]['email']."</li>\n";

Thanks Catalin. I think this was the spacing, it worked with:

echo "<li>" . $contacts[0]['name'] . " : " . $contacts[0]['email'] . "</li>\n"
