PHP Session警告问题

Question

  

可能重复：
  PHP session side-effect warning with global variables as a source of data

我收到来自php

的警告

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

我相信以下代码会产生警告。

 $name=$_SESSION['name'];
 $emails=$_SESSION['email'];

 $_SESSION['info']=array_intersect($name, $emails);

我无法访问php.ini或服务器。我只能改变我的代码。 反正有没有删除警告？

Answer 1

这意味着您有一个与会话变量同名的变量如下所示。

$_SESSION['variable'] = null;
$variable = 'data';

您可以通过在php.ini或.htaccess中将这些行添加到脚本中来阻止PHP尝试查找现有变量并向您发出警告

ini_set('session.bug_compat_warn', 0);
ini_set('session.bug_compat_42', 0);

Answer 2

这将删除错误：

ini_set('session.bug_compat_42',0);
ini_set('session.bug_compat_warn',0);

您也可以从.htaccess文件中删除它，或者如果可用的话，还可以在目录的根目录中关闭它。
