use the array

Required : Replace the hard coded values in the output with the name and email values from the contacts array. Error that I get : Use the contacts array to output the name of each contact.

index.php 
<?php
$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'



];

$contacts[0]['name'];
$contacts[0]['email'];


?>

The following is two examples for creating the associative array:

<?php
$contacts = [
  [
    'name' => 'Alena Holligan',
    'email' => 'alena.holligan@teamtreehouse.com'
  ],
    [
    'name' => 'Dave McFarland',
    'email' => 'dave.mcfarland@teamtreehouse.com'
  ], 
//....
];

// OR
$contacts[] = [
    'name' => 'Alena Holligan',
    'email' => 'alena.holligan@teamtreehouse.com'
  ];
$contacts[] = [
    'name' => 'Dave McFarland',
    'email' => 'dave.mcfarland@teamtreehouse.com'
  ];

The following is an example for echo'ing out the names and emails:

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

For each of the others in the array, replace the 0 with the appropriate index number.

Few things!

  1. $contacts[] appends to the array instead of assigning an array to $contacts (like a variable).

2 .Your name and email assignments are fine for each person, but each person is not inside of their own array.

  1. $contacts[0]['name'] & $contacts[0]['email'] are correct, but you need to insert those for each person into the output string that was already provided.

I am stuck. Couldn't figure it out honestly. I don't know what is wrong exactly. I've tried the below :

<?php

$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',


];

$contacts[0]['name']; 
$contacts[0]['email']; 


?>

Error : Use the contacts array to output the name of each contact.

You haven't done anything that task #3 is asking, "Replace the hard coded values in the output with the name and email values from the contacts array."

Try and figure out the rest from what is below.

<?php

echo "<ul>\n";

echo "<li>".$contacts[0]['name']." : ".$contacts[0]['email']."</li>\n";
// second person here..
// third person here..
// fourth person here..

echo "</ul>\n";
