Problem:If you have a number of PHP pages that need to use a single piece of information, then you could use a link of the form:\n\nhref="/page3.php?var=xyz"\n\nIf it is a small piece of info, like a username, code or id, and you DON'T want it to be visible in the URL itself, then you can pass it as a "hidden" field in a form that is submitted by the POST method.\n\n//This is probably what you are looking for --\nIf it information that needs to be submitted to the server later, such as a registration spanning three pages, use PHP sessions:\n\n(1) In the beginning of the PHP page, call the function session_start()\n\n(2) Store the variable in the $_SESSION array like this:\n$_SESSION['var1'] = "some_value"\n\n(3) In later pages, check if the variable is set like this:\nif(IsSet( $_SESSION['var1'] ))\n    //Do something...use the variable
