How to clear RAM while the script is running?

Question

PHP

There is a script that goes through a huge number of files and folders, makes queries to the database, changes texts, creates subfolders and eats more than 6 GB of RAM in a couple of hours of work. Search in Google gives options only for the case when the script has worked, but the memory has not been freed. I would like to know the options for freeing memory right in the process of running the script?

Answer 1

Use unset() for data that is no longer needed.
