Hi Freaks, I'm looking for advice if someones willing to give it. Here's the situation -> I've been working on a project, I started to learn PHP specifically to complete this idea I had. My code has evolved a lot over time as I've started understanding more. Up until today I've been working on it with just the registration functionality, no login. I had my username hardcoded into the $user_obj instantiation. I decided I wanted to try to make category subscription functionality and doing that I realized I was better off finishing the login form first so as to get a users subscriptions into a session variable at login. This has brought about the issue of getting an unassigned variable warning from the User class when not logged in. How I made all my other classes was putting a $user in the __construct parameter for each class. I now feel this may have been a rookie error since I'm having problems with error messages especially undefined array keys and variables when there isn't a session started. It's become a bit of a mess. So the advice I'm looking for and hoping to find here is how you folks handle non $_SESSION sessions, when a user is just scrolling the site not logged in. Did I make a mistake requiring $user for each class __construct? should I move the $user parameter to only the methods that require them? Is there a simpler solution that my inexperience causes to elude me? What would you folks do in this situation?

I was just researching how to make a proper logout form, seems easy enough. I noticed that a lot of the examples started with session_start(). Are they saying to start it again before destroying it? I don't understand those examples, also a few examples didn't even destroy it but just unset() everything. I also moved my session_start() from config.php to my login handler, it seemed more logical to me. So 2 questions: What IS the proper way to handle a logout - a) start session again to destroy it right away b) just destroy it c) simply unset everything? My heart chooses b) but I've been wrong many times with things that I thought made sense. Also, the session_start() - config.php or login.php? Is there a performance or security difference I should be considering? Good weekend to you all. TIA for responses.

Hey guys, I wanted to share something with everyone. I hope this is helpful. This is basically a native solution to easily store PHP session data in a MySQL database. Session variables contain data that is saved for a specific user by associating the user with a unique identity. Typically, PHP would store session variables in a local file system on the server by default. While this may be acceptable to many people who are running small to moderate PHP applications, some larger applications that require load balancing would need to be run on multiple servers with a load balancer. In such cases, each server running PHP would need a way to ensure that sessions continue to work properly. One common way to achieve this is to override where PHP opens, reads, writes, and destroys the session variables so that it can perform these operations on a table inside of a MySQL database. When this is performed, the web application can gain advantages such as session management, session logging, and session interactions. I have provided my source code for your reference here: https://github.com/dominicklee/PHP-MySQL-Sessions Hope this helps someone out!

There are lots of discussions about this topic online. My issue wasn't subdomain sessions being recognized by the primary domain (and vice versa), but rather just a subdomain handling things at all. You set something in the subdomain, refresh the page, and then the thing was unset. Here's what I currently have: session_name( "blah" ); ini_set( "session.cookie_domain", '.dev.example.com' ); session_set_cookie_params( 0, '/', '.dev.example.com', true, true ); setcookie( session_name(), session_id(), 0, '/' , '.example.com' ); session_start(); Things that were required, apparently: 1) Session name 2) setcookie Now with this setup, I can do this: start session in dev.example.com, access it in subsub.dev.example.com, go back and forth... session holds as expected. But what I cannot do, is: start session in subsub.dev.example.com, refresh page, have the session data hold. So lots of questions. Obviously the most important: why doesn't a session hold when I start the session in the subsub domain? Why is a session name required? (Is it?) Why is setcookie required when all I want to do is start a session? (Is it?) I don't use this step if it's a single-domain type of setup.
