<?php while ($row=$dir->read()) ?>
// will break as soon as $row can be casted to false, which is the case for a directory named "0"
<?php while (false !== ($row=$dir->read())) ?>
// will do the job as expected
use
while ($row=$dir->read()){
// your code
}
to get a list of all files and directories. You can definitely use the "for" and other loops.
