PHP中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。

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

这个错误警告是说：自php 4.2.3起，自动魔术变量转换功能默认关闭。register_globals=off

而传统的session *** 作需要这个开关是打开的。解决方法:

session_start();

$_SESSION['youVar'] = 'youVariableValue';2楼的说对的，是session_register 注册的问题，但是如果不用session_register 那用什么注册?

自问自答

若想取得从另一页面提交的变量:

方法一:在PHP.ini中找到register_global，并把它设置为on.

方法二:在接收网页最前面放上这个extract($_POST);extract($_GET);(注意extract($_SESSION)前必须要有Session_Start()).

方法三:用$_SESSION()注册变量
