Description:
------------
Previously open_basedir would prevent file-functions from accessing protocols such as http. It no longer does, and this change doesn't appear to be documented anywhere. This might simply need an entry in upgrading as is correct according to https://www.php.net/manual/en/function.fopen.php

originally found as https://3v4l.org/oLWdo

Test script:
---------------
$file = 'http://www.phpcodepad.com/index.php';
$newfile = 'example.txt';

copy($file, $newfile);

Expected result:
----------------
Warning: copy(): open_basedir restriction in effect. File(http://www.phpcodepad.com/index.php) is not within the allowed path(s): (/tmp:/in:/etc) in /in/oLWdo on line 5

Actual result:
--------------
Warning: copy(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in /in/oLWdo on line 5
