php - How do I declare a two dimensional array?

Question

What's the easiest way to create a 2d array. I was hoping to be able to do something similar to this:

declare int d[0..m, 0..n]

Answer 1

You can also create an associative array, or a "hash-table" like array, by specifying the index of the array.

$array = array(
    0 => array(
        'name' => 'John Doe',
        'email' => 'john@example.com'
    ),
    1 => array(
        'name' => 'Jane Doe',
        'email' => 'jane@example.com'
    ),
);

Which is equivalent to

$array = array();

$array[0] = array();
$array[0]['name'] = 'John Doe';
$array[0]['email'] = 'john@example.com';

$array[1] = array();
$array[1]['name'] = 'Jane Doe';
$array[1]['email'] = 'jane@example.com';
