How to write log and read?

Question

PHP

Greetings, the question arose about creating a site logging.

I decided to write a small php script that would collect information on the site and write it to a log file located on the server inaccessible to ordinary users.

I decided to record information using JSON strings , so that in the admin panel you could get the log in a specially designated place.

And now the most important question: I can write data to the log file as a JSON string, but how can I read it from the log file?

I do not accept third-party solutions, I try to interact with the code as much as possible, without resorting to a framework and ready-made solutions.

Thank you so much if you give me some of your time!

Answer 1

file_get_contents, json_decode, json_encode
I haven't written on your PHP for a long time, maybe there is something else.
