 New Comment:

Quote from dirname() docs:

dirname() operates naively on the input string, and is not aware of the actual filesystem, or path
components such as "..".

Therefore, dirname( "a/b/c/.." ) will yield "a/b/c" which is not what I want.

>> It's completely unnecessary
Wouldn't say that it is COMPLETELY unnecessary. Otherwise, why do we have dirname() in first
place? We have "..", right?

One of valid use cases is to keep paths without ".." bloat.

This is ancient, but this should be closed. It's completely unnecessary, .. 
exists.

Description:
------------
It would be great if dirname() function had a second parameter, let's say - uint $level, which
would mean "how many path levels to strip off". By default this parameter could be set to
1 to not to break the backwards compatibility.

Reproduce code:
---------------
<?php

$path ='/var/www/localhost/public_html/tpl/';

echo dirname( $path);// /var/www/localhost/public_html
echo dirname( $path, 2);// /var/www/localhost
echo dirname( $path, 3);// /var/www/
echo dirname( $path, 4);// /var
echo dirname( $path, 5);// .
echo dirname( $path, 6);// .

?>

Expected result:
----------------
Expect this feature to be implemented

Actual result:
--------------
-
