PHP and MySQL Optimisation for existing scripts

I have a server based on a LAMP stack hosted on Digital Ocean, with some scripts that download large zipped csv files (one at a time), it then unzips the file and extracts the data in the file into my database tables.

One of the files it downloads is very large (millions of rows, usually) and is causing a few problems with my scripts. i need a PHP and SQL expert to go in an optimise it.

The errors I get are 500 errors and sometimes 524 I think.
