What are you trying to achieve in your code? If you want account numbers that are both in table 1 and table 2, it can be easily done with SQL only. In table 1 but not in table 2? No problem. Database engines have been optimising for these sorts of things for decades, so it will very likely work faster and look cleaner than your current code.

As I understand it, you query for the second table in batches of fifty, leave the last batch of (up to) 50 accounts in $allaccounts, and then print out that variable.

Does the values in @files on line 34 needed to somehow have comma separated in order to the code to work?

I am not familiar with your database library (nor do you anywhere mention which one you are using), but if it supports placeholders such as those you are using, I very much doubt that.
