### Phase 1 cleanup
session_start();
session_destroy();

### Phase 2 $HTTP_SESSION_VARS["c"] does not contain any value
session_id("abtest");
session_register("c");
unset($c);
$c = 3.14;
session_write_close();
unset($HTTP_SESSION_VARS);
unset($c);

### Phase 3 $HTTP_SESSION_VARS["c"] is set
session_start();
var_dump($c);
var_dump($HTTP_SESSION_VARS);
unset($c);
$c = 2.78;

session_write_close();
unset($HTTP_SESSION_VARS);
unset($c);

### Phase 4 final

session_start();
var_dump($c);
var_dump($HTTP_SESSION_VARS);
