Global variable in Drupal module

Posted by sky | Tags: Drupal, Php

There is something different in a variable between a variable in a Drupal module and a variable in a normal php file.

normal php
$_User = "user";
function test() {
  global $_User;
  ..
}

Drupal module
global $_User;
$_User = "user";
function test() {
  global $_User;
  ..
}

In Drupal module, I need the additional global $_User; Why? :?
