php get list of all subdirectories and all files

What is the best way of getting a list of all subdirectories and another list of all files under a given directory in php. I'm okay with a non-pure php code as long as I can use it from php(e.g. a c/java/python/... program). Something faster than pure recursion, something built-in in some language(as these things tend to be fast.)

Since you don't want recursion, I just wrote this up with a few extra bits

// $dirs = [];
// Get All Files & Folders in $dir
$files = glob("$dir/*");
for ($i=0; $i < count($files); $i++) { 
    if (is_dir($files[$i])) {
        $files = array_merge($files, glob("$files[$i]/*"));
    //  $dirs[] = $files[$i]; // This can add the folder to a dir array
    }
}
// Remove folders from the list if you like
foreach ($files as $key => $file) {
    if (is_dir($file)) {
        unset($files[$key]);
    }
}
// Clean up the key numbers if you removed files or folders
$files = array_values($files);

use php's inbuilt RecursiveDirectoryIterator

EDIT

Something like:

$dirs  = array();
$files = array();

$dir = __DIR__ . '/foo';

$iterator = new RecursiveDirectoryIterator(new DirectoryIterator($dir));

foreach ($iterator as $dirElement) {
    if ($dirElement->isDir()) {
        $dirs[] $dirElement->getPathname();
    }
    if ($dirElement->isFile()) {
        $files[] = $dirElement->getPathname();
    }
}

taken from php.nets documentation on glob():

$path[] = 'starting_place/*';

while(count($path) != 0) {
  $v = array_shift($path);

  foreach(glob($v) as $item) {
    if(is_dir($item))
      $path[] = $item . '/*';
    else if (is_file($item)) {
      //do something
    }
  }
}

And if you don't like OOing things, you could perhaps run a loop of opendir() through the results of a find.

if (exec('find /startdir -type d -print', $outputarray)) {
  foreach ($outputarray as $onepath) {
    // do stuff in $onepath
  }
}

You did specify "not pure PHP", as an option, right? :-)

Have a look at the RecursiveDirectoryIterator:

foreach (new RecursiveDirectoryIterator('yourDir') as $file) {
    // you don't want the . and .. dirs, do you?
    if ($file->isDot()) {
        continue;
    }

    if ($file->isDir()) {
        // dir
    } else {
        // file
    }
}
