想在Zend Framework中集成Discuz，但是以下代码的输出让我不太明白：
  1 <?php
  2
  3 require_once dirname(__FILE__) . '/../../public/bbs/include/common.inc.php';
  4
  5 echo "discuz_uid: $discuz_uid<br />";
  6 $a = "aa";
  7
  8 function test_func()
  9 {
10     global $discuz_uid, $a;
11     echo "test_func: discuz_uid: $discuz_uid<br />";
12     echo "aa: $a<br />";
13 }
14
15 test_func();
16
17 class TestController extends Zend_Controller_Action
18 {

在浏览器中输入http://localhost/test/输出为：
discuz_uid: 2
test_func: discuz_uid:
aa:

为什么这个代码写在Controller里，global变量就显示不正确了呢？

用Global变量对于程序不好。

请使用Zend_Registry，可保证变量唯一。

朋友 有结果了 没有？
我说的是 zend framework 与 discuz 整合的问题。
我也在做这方面的工作，毫无头绪，请多多帮助 qq:309470933
