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 also filter out the files after selecting all of them

foreach(glob('my/dir/*') as $file){
    $ext = strtolower(pathinfo($file, PATHINFO_EXTENSION));
    if(!in_array($ext, array('csv'))){
        continue;
    }
    ... do stuff ...
}

performance wise this might not be the best option if for example you have 1 million files that are not csv in the folder.
