PHP get file listing including sub directories

Question

I am trying to retrieve all images in a directory, including all subdirectories. I am currently using

$images = glob("{images/portfolio/*.jpg,images/portfolio/*/*.jpg,images/portfolio/*/*/*.jpg,images/portfolio/*/*/*/*.jpg}",GLOB_BRACE); 

This works, however the results are:

images/portfolio/1.jpg images/portfolio/2.jpg images/portfolio/subdirectory1/1.jpg images/portfolio/subdirectory1/2.jpg images/portfolio/subdirectory2/1.jpg images/portfolio/subdirectory2/2.jpg images/portfolio/subdirectory1/subdirectory1/1.jpg images/portfolio/subdirectory1/subdirectory1/2.jpg 

I want it to do a whole directory branch at a time so the results are:

images/portfolio/1.jpg images/portfolio/2.jpg images/portfolio/subdirectory1/1.jpg images/portfolio/subdirectory1/2.jpg images/portfolio/subdirectory1/subdirectory1/1.jpg images/portfolio/subdirectory1/subdirectory1/2.jpg images/portfolio/subdirectory2/1.jpg images/portfolio/subdirectory2/2.jpg 

Greatly appreciate any help, cheers!

P.S It would also be great if I could just get all subdirectories under portfolio without having to specifically state each directory with a wild card.

from glob example

if ( ! function_exists('glob_recursive')) {     // Does not support flag GLOB_BRACE            function glob_recursive($pattern, $flags = 0)    {      $files = glob($pattern, $flags);      foreach (glob(dirname($pattern).'/*', GLOB_ONLYDIR|GLOB_NOSORT) as $dir)      {        $files = array_merge($files, glob_recursive($dir.'/'.basename($pattern), $flags));      }      return $files;    } }
