### SETUP SESSION VARIABLES

	else $_SESSION['MONKEY'][0] += 1;
	if (!isset($_GET['nochange'])) @$_SESSION['AVAR'] += 1;

	
### START DISPLAY
	print "<h3>PHP ".PHP_VERSION."</h3>";

	print "<hr /> <b>Cookies</b>: ";
	print_r($_COOKIE);
	
	var_dump($_SESSION['MONKEY']);
	
### RANDOMLY PERFORM Garbage Collection
### In real-production environment, this is done for you
### by php's session extension, which calls adodb_sess_gc()
### automatically for you. See php.ini's
### session.cookie_lifetime and session.gc_probability
