$_FANWE是个全局变量，getPhpSelf（）函数是获取当前脚本的函数，程序大大们，到底什么样的场景才会触发这个报错呢，不明白，恳请指明

附：

<code>function getPhpSelf()
{
    $php_self = '';
    $script_name = basename($_SERVER['SCRIPT_FILENAME']);
    if(basename($_SERVER['SCRIPT_NAME']) === $script_name)
        $php_self = $_SERVER['SCRIPT_NAME'];
    else if(basename($_SERVER['PHP_SELF']) === $script_name)
        $php_self = $_SERVER['PHP_SELF'];
    else if(isset($_SERVER['ORIG_SCRIPT_NAME']) && basename($_SERVER['ORIG_SCRIPT_NAME']) === $script_name)
        $php_self = $_SERVER['ORIG_SCRIPT_NAME'];
    else if(($pos = strpos($_SERVER['PHP_SELF'],'/'.$script_name)) !== false)
        $php_self = substr($_SERVER['SCRIPT_NAME'],0,$pos).'/'.$script_name;
    else if(isset($_SERVER['DOCUMENT_ROOT']) && strpos($_SERVER['SCRIPT_FILENAME'],$_SERVER['DOCUMENT_ROOT']) === 0)
        $php_self = str_replace('\\','/',str_replace($_SERVER['DOCUMENT_ROOT'],'',$_SERVER['SCRIPT_FILENAME']));
    else
        return false;
    return $php_self;
}

应该是服务器配置异常的时候。就会出现那个错误了。
