Bug description: file_exists() doesn't work correctly after realpath()
Description:
------------
If the upload_tmp_dir is a symlink, file_exists() doesn't work after a
realpath() call. In my server the default /tmp is a symlink to /home/tmp.
It works if i change the upload_tmp_dir to the /home/tmp. (safe_mode on)
Reproduce code:
---------------
$t = $_FILES["uf"]["tmp_name"];
// $t = /tmp/phpAbcde
// realpath($t) = /home/tmp/phpAbcde
var_dump(file_exists($t)); // true
var_dump(file_exists(realpath($t))); // false
var_dump(is_file($t)); // true
var_dump(is_file(realpath($t))); // false
Expected result:
----------------
I got false when i called the file_exists() and is_file() with
realpath($t).
