Can PHP's glob() be made to find files in a case insensitive manner?

Question

I want all CSV files in a directory, so I use

glob(\'my/dir/*.CSV\')

This however doesn\'t find files with a lowercase CSV extension.

Building on Alex's tip this could help generally:

function glob_files ($d, $e)
{
    $files = preg_grep ("/$e\$/i", glob ("$d/*"));
    sort ($files)
    return $files;
}

where $d is the directory and $e is the extension.
