php sessions are not persistent.

New install using Apache and Php.  Used ray_session_test.php script found here at Experts-exchange.  I can see where the session is being created on in /var/lib/php/session, but it's like the script can't find the session once it's been created.  I'm running the same script on a production server and it works fine, so this is not a php coding issue.

That's a very simple script.  Are you getting any error messages?  How is it not working?  Are you testing it using Chrome on 'localhost'?  If so, it may not be setting the session cookie.  Chrome doesn't set cookies on 'localhost' because it is not a unique address.  Switch to the IP address of the machine and try it.

PHP sessions use HTTP cookies.  If cookies are not accepted and returned the session cannot work correctly.  Try another browser and be sure that you can log into some other application such as Amazon or eBay.  Then close the browser (all windows) and restart the browser.  If you're still logged in to Amazon or eBay, the cookies are working OK, and the PHP session should work OK, too.

Thanks.  Not using localhost and have tried several different browsers.

I've tested with the ray_session_test.php script and I can see the sessions files being created. When I click on the "increment this cheese", a new session id is created.  The increment stops at 2.   I've tested the script on another server and it works perfectly, so we can eliminate php syntax errors.   I'm guessing either a php.ini file setting or apache issue?

cookies are working.

Maybe try running phpinfo() and look for the configuration options associated with the session.  The save_path or cookie_path might be in play.

Here's a screen shot of my session installation.Session information from phpinfo() output

PHP Version 5.3 is obsolete; don't use that.  Upgrade to one of the current versions shown on the PHP home page.

Maybe check permissions on the save path.  Nothing in there jumps out at me!
