function php4_scandir($dir,$listDirectories=false, $skipDots=true) {
$dirArray = array();
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if (($file != "." && $file != "..") || $skipDots == true) {
if($listDirectories == false) { if(is_dir($file)) { continue; } }
array_push($dirArray,basename($file));
}
