If you store your "login object" in a session, when the browser window is closed the object will automatically be destroyed, thus calling the destructor.

exactly what is it that triggers the object destruction??? since when is it normal practice for a browser to do a request to tell a webserver that it is closing [itself]??? you cannot do this at all with just php, HTTP is stateless! it might be possible to use some browser plugin to hit the server if it notices that it's window is being closed... although I have a sneaking suspicion that Flash, for instance, has the same problem as javascript with not being able to differentiate between the page unloading and the window closing. **as far as I know there is NO WAY to tell when the user closes the window, unless you give them a specific way of telling you (e.g. via a 'log off and close the window' link) and they are nice enough to only use the mechanism you provide (fat chance :-). the normal way of doing session 'closing' is by way of 'garbage collection' - every now and then a script/process/function is run that 'closes' any sessions which are (according to your criteria) inactive. php has stuff built it that will do this for you to a degree.

In response to the message you send directly to me, you would create a file called Login.class.php and at the top of each page include the file using require_once("Login.class.php"); Matt ""mail.pmpa"" <mail.pmpa@sapo.pt> wrote in message news:000601c5f480$32976120$6f2e9a52@POSTO03...

The problem is I don't know when a member closes the browser window. If I knew that i would automatically logout that member. Thanks.
