The manual on pear.php.net gives the following example for using pear auth. [code] <?php require_once "Auth.php"; function loginFunction() {     /*      * Change the HTML output so that it fits to your      * application.      */     echo "<form method=\"post\" action=\"test.php\">";     echo "<input type=\"text\" name=\"username\">";     echo "<input type=\"password\" name=\"password\">";     echo "<input type=\"submit\">";     echo "</form>"; } $dsn = "mysql://user:password@localhost/database"; $a = new Auth("DB", $dsn, "loginFunction"); $a->start(); if ($a->checkAuth()) {     /*      * The output of your site goes here.      */ } ?> [/code] How could I refer back to this page without having to show the login form again if the user has already authenticated, or span the authentication over multiple php pages?
