If size is an integer, then, like, just plain old 'sort' should do it, though it's up to you to figure out the multi-dimensional bit. For dates, there are several possiblities... If you Date happens to be Unix timestamp, it's an integer, and is solved by the above. If your Date happens to be in a format not unlike 'Y/M/D' it can be sorted with plain old sort as a string. In situations where Date is in a more natural format, you can use http://php.net/usort and define your own comparison function any which way you want. All that aside, if, like most, this data is coming from the database, you should just use your SQL query to sort the data, if possible, as it will be MUCH more efficient.
