session_register()出错的解决办法

错误提示：warning: unknown(): your script possibly relies on a session side-effect which

existed until php 4.2.3. please be advised that the session extension does not

consider global variables as a source of data, unless register_globals is

enabled. you can disable this functionality and this warning by setting

session.bug_compat_42 or session.bug_compat_warn to off, respectively. in unknown on line 0

1、php4.2以上版本不需要用session_register()注册session变量，直接用：

$_session["string"]=“string";

赋值。

2、用$_session["string"]获取变量值。

3、用$_session["string"][$n]可传递session数组。

两个测试页面：

//a.php

session_start();

echo $_session["x"]++;

//b.php

session_start();

echo $_session["x"];

运行a.php并不断刷新它，看看有什么结果

运行b.php看看能否在页面之间传送结果。

注意：a.php和b.php必须是同一个ie进程！

测试在register_globals = off下进行，一切正常。
