PHP memory issue do you need to undo?

What happens if you don't disconnect the array before the script runs?

I run thousands of CSV files by analyzing data for hundreds of thousands of clients in arrays. It works great for the first 5/6 hours, and then it starts to get sick badly.

I run about 5-10 CSVs for execution ... I wonder if this will help remove arrays in the script or not ... I thought they would not be allocated after the script ends. I am wrong?

As far as I know, arrays - like all memory - should die when the script does.

Unsetjust destroys the variable - it does not free memory. If this behavior occurs after several hours of work, and this is a one-time script, it is possible to split the CSV files into smaller blocks in order to speed up the work and help find out where the problem arises.
