How to quickly load JSON arrays?

Question

PHP

Hello!

Essence:
Suppose there is a foreach array in PHP.
It executes the file_get_contents function 40 to 80 times. Loads JSON data. They are small on their own.

I need to use this array every 5 seconds.
The script is located on a server with VERY fast internet. Average execution time when accessed from a browser: 25.078058004379 (for local understanding, the average script execution is ~127 seconds).

Question:
What are the options to load data faster? Should I use cmd or something else?
Thanks in advance.

If these are local JSONs, then keep them in the database.
If they are taken from a remote server, then cache them in the database, periodically loading them there with a separate script.
