html - PHP Header move up one directory?

Question

How do I specify a file redirect to a file one level above the current file in PHP? Here is my schematic so far:

-landing.html
-ajax
  -checkLogin.php 

checklogin.phphas the following code in it:

header("location:dashboard.html");

This obviously doesn't work since landing.php is one level above. How can I select a file one directory above? I already tried ..landing.php, but seems like it will only take filenames.

You should really use absolute paths (at least relative to your document root).

Consider if you move checkLogin.php a directory deeper…

Any of the follow won't have a problem.

header("Location: /landing.html");
// or
header("Location: http://www.example.com/landing.html");
