如何确定我当前查看的是哪个管理屏幕/子屏幕

Edit: Q缩小到以下范围：

“如何一次检索所有管理UI屏幕的屏幕ID？”

<小时>Edit: 我添加了更多的全局插件。

<小时>Q 是否如下：检查which AdminUI submenu page/screen you\'re viewing 检查一下这个against some global var or some internal function.

// This helps you inspecting the data - just drop it in some functions.php file of a theme
function wpse_inspect_admin_screen_data()
{
    echo \'<pre>\';
        echo \'<h3>global <code>$menu</code></h3>\';
        print_r( $GLOBALS[\'menu\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$submenu</code></h3>\';
        print_r( $GLOBALS[\'submenu\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$self</code></h3>\';
        print_r( $GLOBALS[\'self\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$parent_file</code></h3>\';
        print_r( $GLOBALS[\'parent_file\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$submenu_file</code></h3>\';
        print_r( $GLOBALS[\'submenu_file\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$plugin_page</code></h3>\';
        print_r( $GLOBALS[\'plugin_page\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$admin_page_hooks</code></h3>\';
        print_r( $GLOBALS[\'admin_page_hooks\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$_parent_pages</code></h3>\';
        print_r( $GLOBALS[\'_parent_pages\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$_registered_pages</code></h3>\';
        print_r( $GLOBALS[\'_registered_pages\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$title</code></h3>\';
        print_r( $GLOBALS[\'title\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$_wp_real_parent_file</code></h3>\';
        print_r( $GLOBALS[\'_wp_real_parent_file\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$_wp_menu_nopriv</code></h3>\';
        print_r( $GLOBALS[\'_wp_menu_nopriv\'] );
        echo \'<hr />\';

        echo \'<h3>global <code>$_wp_submenu_nopriv</code></h3>\';
        print_r( $GLOBALS[\'_wp_submenu_nopriv\'] );
        echo \'<hr />\';

        // built by set_current_screen() in /core_root/wp-admin/includes/template.php line 2085 (wp 3.2.x)
        echo \'<h3>global <code>$current_screen</code></h3>\';
        print_r( $GLOBALS[\'current_screen\'] );
    echo \'<pre>\';
}
add_action( \'shutdown\', \'wpse_inspect_admin_screen_data\', 9999 );

我已经有了一个数组，其中包含父菜单项和子菜单项中的slug和Label。在这里，您可以看到我构建的阵列的一个示例部分global $menu, $submenu; 我需要核对一下：

Array
(
    [Appearance] => Array
        (
            [0] => Array
                (
                    [label] => Themes
                    [slug] => themes.php
                    [parent_label] => Appearance
                    [parent_file] => themes.php
                )
            [1] => Array
                (
                    [label] => Widgets
                    [slug] => widgets.php
                    [parent_label] => Appearance
                    [parent_file] => themes.php
                )
            [2] => Array
                (
                    [label] => Editor
                    [slug] => theme-editor.php
                    [parent_label] => Appearance
                    [parent_file] => themes.php
                )
        )
    [Pages] => Array
        (
            [0] => Array
                (
                    [label] => All Pages
                    [slug] => edit.php?post_type=page
                    [parent_label] => Pages
                    [parent_file] => edit.php?post_type=page
                )
            [1] => Array
                (
                    [label] => Add New
                    [slug] => post-new.php?post_type=page
                    [parent_label] => Pages
                    [parent_file] => edit.php?post_type=page
                )
        )
)

<小时>Note: Q不是循环。我只能使用什么来检查当前正在查看的菜单项和子项。
