Wordpress how to use get_current_screen and global pagenow

I do not understand the difference between the following two

According to get_current_screen^Docs:

it'll "return current screen object or null when screen not defined".

If you want to use it to detect admin pages, then use a different hook, for example you could use current_screen hook:

add_action('current_screen', 'detecting_current_screen');
function detecting_current_screen()
{ $current_screen = get_current_screen(); print_r($current_screen);
}

Or

add_action('current_screen', 'detecting_current_screen');
function detecting_current_screen()
{ global $current_screen; print_r($current_screen);
}

If you want to use it on the client-side and that returns null, then you could use a global variable called $pagenow.

Note: $pagenow will give you the template name.

global $pagenow;
echo $pagenow;

Or

echo $GLOBALS["pagenow"];

This should give you the name of the template you're on:

add_action( 'wp_footer', function () { global $pagenow; echo $pagenow;
}, 999 );

If none of the methods, mentioned above, work for you, then you could use another global variable called $post.

Or

You could check your page by using:

get_page_by_title^Docs
or
get_page_by_path^Docs
