How to recursively iterate through files in PHP?

Question

I have set up a basic script that is posting an array of paths to find template files inside them; currently it\'s only searching two levels deep and I\'m having some troubles g

Universal File search in folder, sub-folder :

function dirToArray($dir,$file_name) {
   $result = array();
   $cdir = scandir($dir);
   foreach ($cdir as $key => $value)
   {
      if (!in_array($value,array(".","..")))
      {
         if (is_dir($dir . DIRECTORY_SEPARATOR . $value))
         {
            $result[$value] = dirToArray($dir . DIRECTORY_SEPARATOR . $value,$file_name);
         }
         else
         {
            if($value == $file_name){
                $result[] = $value; 
            }
         }
      }
   }
   return $result;
}

define('ROOT', dirname(__FILE__));
$file_name = 'template.html';
$tree = dirToArray(ROOT,$file_name);
echo "
".print_r($tree,1)."
";

OUTPUT :

Array
(
    [components] => Array
        (
            [side] => Array
                (
                    [second] => Array
                        (
                            [0] => template.html
                            [third] => Array
                                (
                                    [0] => template.html
                                )

                        )

                    [0] => template.html
                )

            [0] => template.html
        )

    [0] => template.html
)
