building a basic php website, add an element to an array

I think this is the right way but cant seem to get it right and I've watched the movie several times.

index.php 
<?php 
$movie = [];
$movie[] = [
  "title" => "The Empire Strikes Back"
  ];
?>
<h1>Back to the Future (1985)</h1>

<table>
  <tr>
    <th>Director</th>
    <td>Robert Zemeckis</td>
  </tr>
  <tr>
    <th>IMDB Rating</th>
    <td>8.5</td>
  </tr>
  <tr>
    <th>IMDB Ranking</th>
    <td>53</td>
  </tr>
</table>

David,

I suggest the following code to pass the challenges assignment task.

<?php
  $movie = [];
  $movie[title] = "The Empire Strikes Back";
?>

There are a couple of ways you can approach the answer here - Bob's answer above is probably the best approach in this scenario (although you need to include quotes within the array key), but for completeness here are all possible methods so you can pick the one that works for you :)

Setting up an array using PHP's array() function You can define an array, then add to it like this

<?php
$movie = array();
$movie['title'] = 'The Empire Strikes Back';
?>

or just add it when you define the array, like this:

<?php
$movie = array('title' => 'The Empire Strikes Back');
?>

Using the square brackets to set up an array Your answer uses this method, so here's the solution using this approach:

<?php
$movie = [];
$movie['title'] = 'The Empire Strikes Back';
?>

Or, define it within the array as you set it up (PHP version 5.4 or later, will cause fatal error on earlier versions)

<?php
$movie = ['title' => 'The Empire Strikes Back'];
?>
