For email confirmations that expire relatively soon, I think the tiny possibility that one person might one day confirm someone else's email is a negligible risk. This function does not need any argument and a single call destroys all the session data. This gives you twice the scope, but will not reduce database seek time. Stand Out as the employee with proven skills. Note: To access the session data in the same page there is no need to recreate the session since it has been already started on the top of the page.

However, the time you spend writing that snippet of code is likely wasted as it will most likely never be run. You then just have to change the values of each session. Edit: Indeed, it would work as StarLion outlined above. The answer was simply that you need to have the domain be consistent for sessions to work consistently. Parameters id If id is specified, it will replace the current session id. You can use something like this: md5 microtime ; You can combine more values together, e. This may cause undesired results if the session id is stored in a db and checked, a solution is to check at the new entry point new tab or window if the user went back to the index page for an existing session.
But for uniqueness you will always need to look into table if there isn't such hash already stored but the probability is very low of course. Are you sure this sql is returnign something? Hope this helps someone out there. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform. Note: There is a cool standard called that allows the payload to carry the information. Just want to make sure someone doesn't think they can just use uniqid and be done with it. I re-created the php directory. Thanks for the time spent on this.
It's all new to me, and I want to ensure the best work. Once they receive session Id from the server, users send it back in the following requests to identify themselves. You could find more useful code snippets here. An explanation for the record. Just a question about the clean-up you mentioned. A quick google-fu turns up that you might want to edit your server's setting if this becomes a notable problem.
You cannot absolutely guarantee uniqueness, but the probabilities are so low of hitting the same hash twice that it is, generally speaking, not worth worrying about. As mentioned its very rare this would happen, especially on a site with only 5k unique visitors a day. I re-created the session directory in the php directory, and session stuff resumed working. Immediate session data deletion disables session hijack attack detection and prevention also. Env: localhost Note: condition is mandatory, otherwise it destroys on each load. You will then need to detect collisions manually, e.
So much so, it is not worth worrying about unless you have lots of concurrent users. I wrote the following code for a project I'm working on- it attempts to resolve the regenerate issue, as well as deal with a couple of other session related things. Because is based on the time, and according to php. Basically, it is only overriding the system's default session save handler. You can adjust this timeout duration by changing the value of session. Another gotcha to add to this list is that using a relative session.
Since there isn't anything you can do with the session once you've changed your id, it's kind of pointless to change your id this way. If however it does not then it is satisfactory. There are some good ideas here for you to choose from, but I figured that I'd throw in a possibility too. I would highly recommend not rolling out your custom session handling code, unless you absolutely have to. The documentation to do this is scattered all around different sites, especially in comments sections rather than examples.
If an error comes up, the key was already used, so you'll need to re-generate another. You need to read it from the configuration by accessing the property: System. These are the basics for me, but you can build upon. One difficulty I encountered was the session save handler for one of the applications was set, whereas the other was not. It doesn't appear in the documentation, or in anyone's comment here, but setting session. With the encryption used there, this is sufficient if you are the only one seeing the source of the script.
