Why does isDot() fail on me? (PHP)

Question

I\'m finalizing a code segment that lists the files in a directory. I have no problems listing the files in a directory but for some reason I can get the isDot() method to work

Answer 1

The other answer is excellent, but for a different approach you can set the SKIP_DOTS flag:

setFlags(RecursiveDirectoryIterator::SKIP_DOTS);
$o_iter = new RecursiveIteratorIterator($o_dir);

foreach ($o_iter as $o_info) {
   echo $o_info->getPathname(), "\n";
}
