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 try this, but second dimension values will be equals to indexes:

$array = array_fill_keys(range(0,5), range(0,5));

a little more complicated for empty array:

$array = array_fill_keys(range(0, 5), array_fill_keys(range(0, 5), null));
