Description:
------------
If you have a .phar in a directory that contains spaces (e.g. "/some/path with spaces/example.phar") it is not possible to read files in that phar using their full and escaped path (e.g. "phar:///some/path%20with%20spaces/example.phar/README").

This got to my attention since simplexml_load_file always escapes the provided paths.




Test script:
---------------
<?php
$readme = file_get_contents('phar:///some/path%20with%20spaces/example.phar/README');

Expected result:
----------------
$readme contains data from "phar:///some/path with spaces/example.phar/README"

Actual result:
--------------
PHP Warning:  file_get_contents(phar:///some/path%20with%20spaces/example.phar/README): failed to open stream: phar error: invalid url or non-existent phar "phar:///some/path%20with%20spaces/example.phar/README" in *** on line 2
