Description:
------------
If a file_get_contents call to an external URL fails, due to e.g. a 404, the error log in Apache shows a version of the requested URL with entities, rather than the actual URL, as if it were intended for display:

PHP Warning:  file_get_contents(http://www.example.com/api?foo=1&bar=2): failed to open stream: HTTP request failed! HTTP/1.0 404 Not Found\r\n in /path/to/foo.php on line 3

This means that, after checking the log, the URL cannot be copied-and-pasted from directly.

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

echo file_get_contents ('http://www.example.com/api?foo=1&bar=2');

?>

Expected result:
----------------
PHP Warning:  file_get_contents(http://www.example.com/api?foo=1&bar=2): failed to open stream: HTTP request failed! HTTP/1.0 404 Not Found\r\n in /path/to/foo.php on line 3

Actual result:
--------------
PHP Warning:  file_get_contents(http://www.example.com/api?foo=1&amp;bar=2): failed to open stream: HTTP request failed! HTTP/1.0 404 Not Found\r\n in /path/to/foo.php on line 3
