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

$r = array("arr1","arr2");

to echo a single array element you should write:

echo $r[0];
echo $r[1];

output would be: arr1 arr2
