would that work?
$car = $strictLeadingDot ? '(?:/(?=[^\.])[^/]*+)+' : '(?:/[^/]*+)+'

Nup, it's not. I tried to make it working with a one-liner like that but all my attempts were either not matching "deep children" (level + 1) or matching the folder without its slash (like foo for foo/**)

I think this $car creation is also more readable.

if (!isset($glob[$i + 3])) {
$car .= '?';
}

if ($strictLeadingDot) {
$car = '(?=[^\.])'.$car;
}

$car = '/(?:'.$car.')*';
$i += 2 + isset($glob[$i + 3]);

if ('/' === $delimiter) {
$car = str_replace('/', '\\/', $car);
}
