Running out of memory building csv file

Question

I'm attempting to write a script that does a query on my
database. It will generally be working with about 10,000 - 15,000
records. It then checks to see if a certain file exists. If it
does, it will add the record to an array. When its done looping
over all the records, it takes the array that was created and
outputs a csv file (usually with about 5,000 - 10,000 lines).
But... before that ever happens, it runs out of memory. What can I
do to make it not run out of memory?

Sounds pretty inefficient to me. Is there no way you can
modify the query so that it only selects the records for which the
file exists?
