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.

You can write your own case insensitive glob. This is from a personal web library I write:

/** PHP has no case insensitive globbing
 * so we have to build our own.
 *
 * $base will be the initial part of the path which doesn't need case insensitive
 * globbing.
 * Suffix is similar - it will not be made insensitive
 * Make good use of $base and $suffix to keep $pat simple and fast in use.
 */
    function ciGlob($pat, $base = '', $suffix = '')
    {
        $p = $base;
        for($x=0; $x
