Karl,
This works for small datasets, but when you have a large amount of data
(either in terms of storage or row count) it is no longer practical.
This is why people typically use the SQL row count instead of transferring
all of the data to php and doing the work there. It is much more efficient.
(You may wish to read about buffered vs unbuffered queries)
