[Sessions] different behaviour between localhost and hosting ......

whisher06

Hi.
Sorry to disturb you but I've got a strange trouble
with sessions.
The script on the localhost works fine but in my hosting
I've got this ugly error

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/sub/sc1-LOWM/www/blogialnewversion/admin/admin-inc.php:1) in ...............

I worked out the trouble with ob_start() but
I don't understand what on hell is different may be in php.ini.

Do you have any ideas about that ?

Best wishes.

The error occurs because something generated output prior to your session_start() call. If the main script is identical in both situations, then the only thing I can think of is if the script calls any include files first, and there is some difference between the files being included.

I suppose another possibility would be if the error reporting settings are different and some sort of notice or warning is being generated prior to your session_start() call.

Are the operating system, PHP, web server versions all identical between development and production?
Is the PHP build the same between development and production (i.e. at least identical build options, preferably the same binary)
Are all PHP and web server configuration options identical between development and production?

If the answer to any of these is "No", then you need further work to get a properly consistent development environment.

Another possibility might be that (despite everything being the same on the sevrer) the behaviour of the browser is different on a server called "localhost" - this is certainly the case (often) in Internet Explorer.

I recommend you set up a domain name for your development site which is similar to production (don't register one, just use an internal-only name only visible to you and/or your colleagues- run a private DNS or uses a "hosts" file if you really want to). In particular, it should be in the same top-level domain and contain the same number of dots (or maybe more is ok). Cookies behave in a way which is dependent (to some extent) domain names.

Thanks a lot buddy.
I tried to put all the stuff (constant and db connection and all the objects) in the main page and the script works 😉

Thanks a lot buddy.
I'm going to never work on localhost (only for the little snippets)
thanks a lot for the tips 😉

Sorry the masterpiece 😃

Hi buddies 😉
I'm a little pigheaded and I am not very pleased to have all the
stuff in the main page (and I known that there was something wrong in the script)
so after three days with a sore headache
I found the silly error.
In a include file (the confic-inc) there was something wrong
(no white space or other) so I just delete it and I created
a brand new file a the script magically works 😃

I'm wondering what on hell there was wrong in the file ? 😕

Even if the file was created by windows so (my hosting have got linux so)
I edit it several times with my on line filemanager.

Have you known any reasons for that ?

Bye.
