I am using get_images() to scan directory images.
This function works exactly the way i want on WINDOWS but not on LINUX

Code:

$this->gallery_path = realpath(APPPATH . '../'.$a);
$this->gallery_path_url = base_url().$a.'/';

$data['images'] = $this->get_images();

Code:

function get_images() {

Line 60:$files = scandir($this->gallery_path);
Line 61:$files = array_diff($files, array('.', '..', 'thumbs'));
  $images = array();
Line 63:foreach ($files as $file) {
   $images []= array (
    'name' => $file,
    'url' => $this->gallery_path_url . $file,
    'thumb_url' => $this->gallery_path_url . 'thumbs/' . $file
   );
  }
  
  return $images;
}
