Description:
------------
When open_basedir is set to something other than "no value" the copy function 
fails when trying to read from php://input with the following message:

Warning: copy(): open_basedir restriction in effect. File(php://input) is not 
within the allowed path(s): (d:\server)

However, when trying file_get_contents('php://input') it successfully reads the 
data.

Test script:
---------------
<?php
copy('php://input','destination.txt');
?>

Expected result:
----------------
Expected a new file to be created "destination.txt" with the contents of 
php://input

Actual result:
--------------
Warning: copy(): open_basedir restriction in effect. File(php://input) is not 
within the allowed path(s): (d:\server)
