EXTRAS - SESSIONS

From PHP 5.6 session data is only written if data has been changed.

This can cause some weird problems, like "randomly" logging out of users

Solution: write something every time

Read more here

$_SESSION['someKey'] = some_changeable_value; // time()

EXTRAS - $HTTP_RAW_POST_DATA

Deprecated from PHP 5.6

setting in php.ini defines how data is written in

Solution:

always_populate_raw_post_data$HTTP_RAW_POST_DATA

always_populate_raw_post_data = ‐1
