$_SERVER['PHP_SELF'] only relates to the main script, not the currently
included file. It's useful, but a completely separate issue.

There is, as far as I can see, no way to get the non symlink resolved
path of the currently included file.

$_SERVER["PHP_SELF"] helps a little.

Description:
------------
See these bugs:
http://bugs.php.net/bug.php?id=38790
http://bugs.php.net/bug.php?id=42516
http://bugs.php.net/bug.php?id=37603

The __FILE__ constant should not, in my opinion, resolve symbolic links
on *nix operating systems. At the very least, there should be an option
to control this behaviour.

Because __FILE__ returns only the symlink resolved path, there is no
way to get the symlink path of the currently included file. If __FILE__
returned the symlinkpath, the resolved path could be retrieved with
realpath(__FILE__).

The opposite is not true. There is no way to go from the resolved path
to the original link path. I realise this is a feature not a bug, but I
believe it is a serious shortcoming and limits the ability of PHP in
symlinked situations.

Reproduce code:
---------------
See http://bugs.php.net/bug.php?id=37603

Expected result:
----------------
__FILE__ should return the symlink path

Actual result:
--------------
__FILE__ returns the resolved path
