Description:
------------
Currently file_exists() is case insensitive on Windows, but not on *nix platforms. 
This makes it difficult to migrate from Windows back to *nix. Forcing 
file_exists() to always be case insensitive would be of great benefit in these 
scenarios. I'm not sure what the engineering behind it would involve, but I 
thought I'd ask!

Test script:
---------------
<?php

$dir = dirname(__FILE__) . DIRECTORY_SEPARATOR;
var_dump(file_exists($dir . 'cAsE_mAtTeRs.php'));

?>

Expected result:
----------------
true

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

PHP relies on the underlying semantics of the file system: if the file system is case insensitive (and some file systems are or optionally can be on *nix systems — for example, HFS+ on OS X), then PHP will behave accordingly.

Having PHP behave differently to other programs on the same system would definitely violate the principle of least surprise, quite aside from the (non-trivial) amount of work required.

Closing Won't Fix.
