Web page not refreshing

[selvam]

I am very new to PHP. I am creating an object and storing it within an array. Upon clicking a submit button I am refreshing the page by counting the array and populating a table on the page with the values found from the object within the array. This works fine. But once I close my browser and reopen the same page, all the values on the table still remain there! Added to that even though I don't click the submit button, but just press the refresh button in the browser, the table data gets populated as if the submit button is pressed!!!

How can I code to make sure that the data on the page does not remain there once the user has gone to another page or closed the browser. Just for your information, I'm using session_register to register the array. I am using apache as the webserver running on Linux redhat 8.

Please shed some light on the matter.

Use session_unregister()

so you have to make them "logout" or something. There is probably a better way but I am not aware of it.

at which instance should i be putting the session_unregister function? I wish to to put it when the user visits the page, refreshes it and leaves the page. So what would be the $HTTP_POST_VARS equivalant for each of these actions?

just use a count variable

if ($count == 1) {

// if first visit

// show everything

} else {

// give a logout link here or

session_unregister("whatever its name is");

}
