How to get URL relative "deepness"?

In PHP, how would I get the URL relative indicators based on where I'm located? Examples:

Location                 Return

example.com              ./
example.com/sub          ../
example.com/sub/sub      ../../

...
Solution

  • Considering your above example:

    $url = 'example.com/sub/sub/';
$parts = explode('/', $url);
$parts = array_filter($parts, 'strlen');
$path = count($parts) == 1 ? './' : str_repeat('../', count($parts)-1);

    This code ignores the empty parts and trailing slashes (e.g.: example.com//sub/).
