[RESOLVED] problem caused by difference between Linux php and Win NT php ?

VisionsOfCody

I've got a very strange problem with an admin interface I'm working on

when the admin logs on, the db returns all the permissions which are put into an array in a session variable

this seesion var is used right through the admin to configure the main navigation in the left column and also to decide which content they can access

ok so far so good, but the problem is this :

when i uploaded the whole thing to a distant server it all works fine except that there are 2 pages (one is more-or-less a copy of the other) that cause the whole thing to go pear-shaped

but what's really wierd is that if I log on and go directly to the "news" section admin page then all is well

but if i log on, go to one of the two problematic pages and THEN go to the "news" page, the left nav and the content just disappear

and I have to clear the session cookies and re-log in to get the the left nav and content to work again

I can't see anything directly in the two 'problem' pages - and most of their content is just includes that are used in most of the other pages too

AS i said this is not a problem on my local machine running easyphp (version 4.3.3 on windows NT) but it IS a problem on the distant server running php 4.4.2 on Linux

I'm not using any Win NT specific modules in my code - it's real basic standard php

This kind of logically leads me to think that it's some kind of issue between how sessions are handled on the two systems

has anyone got any ideas what this could be ????

thanks

You should enable all errors and warnings being logged into your error log, then consult it.

We cannot guess.

I don't have access to the server config - it's on shared hosting

what can i do to access the error log ?

thanks

Just get your support people to give you access to the error log. If they can't, then change hosts, as they are obviously crap.

ok thanks

I found out the problem - I have a session variable called $_SESSION['admin_status'] used in all admin pages and a local variable called $admin_status in the pages that caused the problems

windows apparantly let that one slip right through but Linux was having none of it !

thanks for your help anyway

Probably your register_globals parameter is set differently. Keep it turned off.

You should configure your dev and production box as closely as possible. Ideally they should run the same OS too.
