    $matrix = array();
             


        

Answer 1

The default PHP array implementation is very memory-intensive. If you are just storing integers (and lots of them), you probably want to look at SplFixedArray. It uses a regular contiguous memory block to store the data, as opposed to the traditional hash structure.
