I'm trying to make a folder, and then two more folders in that directory. For some reason, it only makes the first folder, but it doesn't make the last two folders.

mkdir($_SERVER['DOCUMENT_ROOT'] . "/images/gallery/$newdir", true);
mkdir($_SERVER['DOCUMENT_ROOT'] . "/images/gallery/$newdir/thumb", true);
mkdir($_SERVER['DOCUMENT_ROOT'] . "/images/gallery/$newdir/full", true);

Safemode is off.

EDIT: Nevermind, fixed it.

mkdir($_SERVER['DOCUMENT_ROOT'] . "/images/gallery/$newdir", 0777, true);
mkdir($_SERVER['DOCUMENT_ROOT'] . "/images/gallery/$newdir/thumb", 0777, true);
mkdir($_SERVER['DOCUMENT_ROOT'] . "/images/gallery/$newdir/full", 0777, true);
