Description:
------------
I'd love to see a glob_filter() function that filters an array of file paths for those file paths matching a glob, with the same rules used by glob(). This function is needed when a virtual file system (implemented in PHP) should be globbed for files.

Signature:

glob_filter(array $paths, string $glob[, int $flags = 0])

$paths - an array of file system paths
$glob - a glob
$flags - the glob() flags

Result: an array of matching file system paths

Test script:
---------------
$input = array(
    '/css',
    '/css/reset.css',
    '/css/style.css',
    '/js',
    '/js/script.js',
);

foreach (glob_filter($input, '/*/*.css') as $path) {
    echo $path."\n";
}

Expected result:
----------------
/css/reset.css
/css/style.css
