What is the format for storing session data in PHP?

Question

PHP

There was a need to work with the saved session data directly.

I put some data in the session, for example

$_SESSION['id'] = 100500;

In the place where the session is saved, I expect to see:

id|i:100500;

but I get

Ilsl4dNDgOPRqC2FwZ-OxeBxcn1qtO6IbkFAEh1zfoQ.

.

In the settings is:
session.serialize_handler=php

Answer 1

Dig in the direction of suhosin.session. * (especially suhosin.session.encrypt, the name is too hinting)

Answer 2

Is the code shown a real example or just for demonstration purposes? If the demonstration is actually more complicated, then it is possible to use your own serialize_handler, set via session_set_save_handler and using a binary format.

Answer 3

Some kind of perversion ...
Use files or a cache if you need to transfer / change some user data. By changing sessions directly, you risk running into data loss or blocking.
