register_globals has been deprecated since PHP 5.3, which was released 5 years ago. There's absolutely no reason anyone should have this turned on, and if they do, well, they probably have bigger issues than this. Due to changes in WebStart.php, the web installer will now fail to start, just showing an error message stating that register_globals must be disabled beforehand. The command-line installer will display the "config-register-globals-error" message before exiting. Change-Id: If951d15293c5f6aa8a92e91fefcb00f04e6c13b3
