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

For a simple, "fill as you go" kind of solution:

$foo = array(array());

This will get you a flexible pseudo two dimensional array that can hold $foo[n][n] where n <= ∞ (of course your limited by the usual constraints of memory size, but you get the idea I hope). This could, in theory, be extended to create as many sub arrays as you need.
