The returned object is an iterator of SplFileInfo objects.

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 new
IgnorantRecursiveDirectoryIterator($this->getPathname());
        } catch(
UnexpectedValueException $e) {
            return new
RecursiveArrayIterator(array());
        }
    }
}
?>

Use just like the normal RecursiveDirectoryIterator.

If you need to convert a nested directory tree into a multidimensional array, use this code:

<?php
$ritit
= new RecursiveIteratorIterator(new RecursiveDirectoryIterator($startpath), RecursiveIteratorIterator::CHILD_FIRST);
$r = array();
foreach (
$ritit as $splFileInfo) {
  
$path = $splFileInfo->isDir()
         ? array(
$splFileInfo->getFilename() => array())
         : array(
$splFileInfo->getFilename());

   for (
$depth = $ritit->getDepth() - 1; $depth >= 0; $depth--) {
      
$path = array($ritit->getSubIterator($depth)->current()->getFilename() => $path);
   }
  
$r = array_merge_recursive($r, $path);
}

print_r($r);
?>

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.

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.

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);
}
?>
