CF style Client Variables

Anon

Is there anything like ColdFusion's Client Variables? Application Variables were actually easy to implement, but right now, I was wondering if there was any way to implement client variables without cookies, storing them in a local database, much the same way CF does.

What I mean is this (I'm new at this, and I'm not sure if I'm coming across clearly): I want a session that will only end when the user presses the logout buton, and last for however long I set it to, regardless of whether the user has closed the browser, rebooted, etc.

SCT.

Interesting. What does CF use to key these variables?

Yes, you can do this. Use session_register to instantiate variables you need between pages. You can then unregister them when the user logs out.

Sessions have several modes of operation - only one of which requires cookies. Given the fact that Hotmail, New York Times and other mainstream sites require cookies, I don't think it's onerous to ask that users have cookies enabled.

However, if you don't want to use them, you can manually track a session id in your pages (e.g., by using a hidden field). This is just a little more work though.

According to them, Cookies, Registry, or External Depository.

This page explains it better than I could.

Alas, this page explains where the client data is stored, but that's not what I was asking. My concern is how you ID the client on each successive http transaction. I had assumed that when you said "without cookies" you meant without using cookies to store the session id; but looking at this CF stuff perhaps you only meant without trying to stuff all the data into cookies.

So let me just say that using PHP sessions will probably do what you want, and as Dave has just noted, you can use cookies OR a url-based id to keep track of the session itself; all the storage is in files on the server (which PHP manages automatically for you.)
