Bug description: require_once() distinguishes backslashes from forward slashes
Description:
------------
When including a file, require_once() will make a destinction between
path/file strings containing forward slashes and backslashes.
Reproduce code:
---------------
(example)
function __autoload($className){
$basePath = 'C:/htdocs';
$classPath= $basePath . '/classes';
require_once($classPath . "/$className.class.php");
}
// Some function that doesn't resolves paths
function getPath($file){
$path = realpath('./$file');
return $path;
}
// Autoload
$A = new Foo;
// Explicit require of class
require_once(getPath(Foo.class.php));
$B = new Foo;
Expected result:
----------------
One would expect the require_once to notice that Foo has already been
loaded and not include the file a second time.
Actual result:
--------------
Fatal error: Cannot redeclare class foo in c:\htdocs\classes\Foo.class.php
on line n
(or something like that)
Whatever the actual result, the file is loaded twice, as the slashes
produced by realpath are distinguished from the slashes used in the
defined __autoload() function.
