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.

For starters, you're missing a slash, ie ../landing.html

You mean ../landing.php?

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");

The accepted answer will take you to the root of the domain, not 1 folder up as specified.

To go one folder up:

header("Location: ../landing.html");

~~I think it is because you forgot the / after the ..~~

~~header("Location: ../landing.php");~~

Update: As noted in comments, this is not up to specification, and should be an absolute URI. Another method if you can't get the absolute path for some reason is to use:

$parent = dirname($_SERVER['REQUEST_URI']);
header("Location: $parent/landing.php");

w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.30 "The field value consists of a single absolute URI."

s/landing\.php/landing\.html

@zerkms A pedantic programmer would certainly use an absolute URI whereas the pragmatic know that modern user agents can interpret a relative URL just fine

@zerkms this is a "strict" format. Browsers will still follow it as expected.

@doitlikejustin: this is a specification. Do you expect browsers to follow HTML specification? And what about HTTP?

This is the solution which helped me redirect back to the Root(Home) directory.

<?php

    header('Refresh:0 , url=/ROOT_DIR/');

?>
