How do you limit PHP memory usage when processing MySQL query results?
So I have a PHP page that allows users to download CSV for what could be a whole bunch of records. The problem is the more results the MySQL query returns, the more memory it uses.

I was curious about the performance of insert-sort using C and python but the results I've got just make me think if I've done something wrong. I suspected that C would be faster, but not that much.
