A function I created to non-recursively get the path of all files and folders including sub-directories of a given folder.

Though I have not tested it completely, it seems to be working.



<?php



/**

 * Finds path, relative to the given root folder, of all files and directories in the given directory and its sub-directories non recursively.

 * Will return an array of the form 

 * array(

 *   'files' => [],

 *   'dirs'  => [],

 * )

 * @author sreekumar

 * @param string $root

 * @result array

 */

function read_all_files($root = '.'){

  $files  = array('files'=>array(), 'dirs'=>array());

  $directories  = array();

  $last_letter  = $root[strlen($root)-1];

  $root  = ($last_letter == '\\' || $last_letter == '/') ? $root : $root.DIRECTORY_SEPARATOR;

  

  $directories[]  = $root;

  

  while (sizeof($directories)) {

    $dir  = array_pop($directories);

    if ($handle = opendir($dir)) {

      while (false !== ($file = readdir($handle))) {

        if ($file == '.' || $file == '..') {

          continue;

        }

        $file  = $dir.$file;

        if (is_dir($file)) {

          $directory_path = $file.DIRECTORY_SEPARATOR;

          array_push($directories, $directory_path);

          $files['dirs'][]  = $directory_path;

        } elseif (is_file($file)) {

          $files['files'][]  = $file;

        }

      }

      closedir($handle);

    }

  }

  

  return $files;

}

?>
