count full listing of files in subdirectories php

I have this function I retrieve all the subfolders files (5000), from an specific directory /gifs ...and renames them (works well)

PROBLEM

I want to return a number of row li so it could be renamed with this number, I want any li have a correlative number that increases in one from file 0 to 5000. with this current function it returns correlative to the number of gifs per folder and then restars in the next folder...

$dir = '../gifs';

function listFolderFiles($dir){

  $results = new DirectoryIterator($dir);

  echo '<ul>';

  $count = 1;
  foreach($results as $fileInfo){

      if($fileInfo->isFile()){

        $oldFileName = $fileInfo->getPathname();
        $newFileName = $fileInfo->getPath() . '/' . $count . '.gif';

        //rename($oldFileName, $newFileName);

        echo '<li>' . 'File  Old: ' . $oldFileName . '  New: ' . $newFileName . '</li>';

        $count++;

      }

      if($fileInfo->isDir() && !$fileInfo->isDot()){

        echo '<li>' . 'Folder: ' . $fileInfo->getPathname() . '</li>';
        listFolderFiles($fileInfo->getPathname());

      }

  }

  echo '</ul>';



}


listFolderFiles($dir);

this is some of the files estructures, most of all have parenthesis on their names...

Everytime the function is executed, $count is set to 1. To get around this, define $count outside the function and use global $count; inside your function to tell PHP that you want $count to refer to the variable outside the function's scope.

Here's the code

$dir = 'gifs';
$count = 1;

function listFolderFiles($dir){
  global $count;
  $results = new DirectoryIterator($dir);

  echo '<ul>';

  foreach($results as $fileInfo){

  if($fileInfo->isFile()){

    $oldFileName = $fileInfo->getPathname();
    $newFileName = $fileInfo->getPath() . '/' . $count . '.gif';

    //rename($oldFileName, $newFileName);

    echo '<li>' . 'File  Old: ' . $oldFileName . '  New: ' . $newFileName . '</li>';

    $count++;

  }

  if($fileInfo->isDir() && !$fileInfo->isDot()){

    echo '<li>' . 'Folder: ' . $fileInfo->getPathname() . '</li>';
    listFolderFiles($fileInfo->getPathname());

  }

  }

  echo '</ul>';



}


listFolderFiles($dir);
