Operating system: Linux

PHP Bug Type:     Feature/Change Request
Bug description:  __FILE__ should not resolve symlink paths

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
