Description:
------------
If an URL with an unsupported protocol is passed to filesystem
functions, they treat it as local file path (after raising an
E_WARNING).  On Linux, however, file_get_contents() and others may
succeed, even if file_exists() returns FALSE (Windows returns
TRUE).

The test script is supposed to be placed in
ext/standard/tests/streams/ and to be run from the php-src root.



Test script:
---------------
<?php
$path = "foobar://google.com/../../INSTALL";
var_dump(file_exists($path));
var_dump(file_get_contents($path, false, null, 0, 10));
?>

Expected result:
----------------
Warning: file_exists(): Unable to find the wrapper "foobar" - did you forget to enable it when you configured PHP? in %s on line %d
bool(true)

Warning: file_get_contents(): Unable to find the wrapper "foobar" - did you forget to enable it when you configured PHP? in %s on line %d
string(10) "For instal"

Actual result:
--------------
Warning: file_exists(): Unable to find the wrapper "foobar" - did you forget to enable it when you configured PHP? in %s on line %d
bool(false)

Warning: file_get_contents(): Unable to find the wrapper "foobar" - did you forget to enable it when you configured PHP? in %s on line %d
string(10) "For instal"
