- RecursiveDirectoryIterator::__construct — Constructs a RecursiveDirectoryIterator
- RecursiveDirectoryIterator::getChildren — Retorna um iterador para o elemento atual se ele for um diretório
- RecursiveDirectoryIterator::getSubPath — Get sub path
- RecursiveDirectoryIterator::getSubPathname — Get sub path and name
- RecursiveDirectoryIterator::hasChildren — Retorna se o elemento atual é ou não um diretório que não seja '.' nem '..'
- RecursiveDirectoryIterator::key — Retorna o caminho e o nome do arquivo do elemento atual do diretório
- RecursiveDirectoryIterator::next — Avança para o próximo elemento
- RecursiveDirectoryIterator::rewind — Recomeça a iteração do diretório

Here is how to empty a directory using iterator:
<?php
function empty_dir($dir) {
$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir),
RecursiveIteratorIterator::CHILD_FIRST);
foreach ($iterator as $path) {
if ($path->isDir()) {
rmdir($path->__toString());
} else {
unlink($path->__toString());
}
}
// rmdir($dir);
}
?>

If you use RecursiveDirectoryIterator with RecursiveIteratorIterator and run into UnexpectedValueException you may use this little hack to ignore those directories, such as lost+found on linux.
<?php
class IgnorantRecursiveDirectoryIterator extends RecursiveDirectoryIterator {
function getChildren() {
try {
return parent::getChildren();
} catch(UnexpectedValueException $e) {
return new RecursiveArrayIterator(array());
}
}
}
?>
Use just like the normal RecursiveDirectoryIterator.

If you would like to get, say, all the *.php files in your project folder, recursively, you could use the following:
<?php
$Directory = new RecursiveDirectoryIterator('path/to/project/');
$Iterator = new RecursiveIteratorIterator($Directory);
$Regex = new RegexIterator($Iterator, '/^.+\.php$/i', RecursiveRegexIterator::GET_MATCH);
?>
$Regex will contain a single index array for each PHP file.

Usage example:
To see all the files, and count the space usage:
<?php
$ite=new RecursiveDirectoryIterator("/path/");
$bytestotal=0;
$nbfiles=0;
foreach (new RecursiveIteratorIterator($ite) as $filename=>$cur) {
$filesize=$cur->getSize();
$bytestotal+=$filesize;
$nbfiles++;
echo "$filename => $filesize\n";
}
$bytestotal=number_format($bytestotal);
echo "Total: $nbfiles files, $bytestotal bytes\n";
?>

If you don't get a fully recursive listing, remember to check your permissions on the folders. I just spent 2 hours to find out my root folder didn't have +x on it. I did a chmod g+x and now get a full listing. Oddly, I was able to get a listing of files/folders one level UNDER that folder, but nothing beyond that point which was cause for the confusion.

Usage example:
<?php
$path = realpath('/etc');
$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
foreach($objects as $name => $object){
echo "$name\n";
}
?>
This prints a list of all files and directories under $path (including $path ifself). If you want to omit directories, remove the RecursiveIteratorIterator::SELF_FIRST part.
