Hello,
I get this warning with my PHP code sometimes. It will come up, and
then after reloading the page once or twice, it will go away. Any
ideas? The code is below:
Warning: Unknown: Your script possibly relies on a session side-effect
which existed until PHP 4.2.3. Please be advised that the session
extension does not consider global variables as a source of data,
unless register_globals is enabled. You can disable this functionality
and this warning by setting session.bug_compat_42 or
session.bug_compat_warn to off, respectively. in Unknown on line 0
I understand that this has to do with using session_register, but I
don't use that anywhere in my code. My code looks like below:
<?php
session_start();
