PHP: sort folder first and then files

Question

$dir = '/master/files';
$files = scandir($dir);
foreach($files as $file){
   if(($file != '.') && ($file != '..')){
      if(is_dir($dir.'/'.$file)){
         echo '<li class="folder">'.$file.'</li>';
      }else{
         echo '<li class="file">'.$file.'</li>';
      }
   }
}

From the script above, I get result:

images (folder)
index.html    
javascript (folder)
style.css

How to sort the folder first and then files?

Answer 1

Try this :

$dir = '/master/files';
$directories = array();
$files_list  = array();
$files = scandir($dir);
foreach($files as $file){
   if(($file != '.') && ($file != '..')){
      if(is_dir($dir.'/'.$file)){
         $directories[]  = $file;

      }else{
         $files_list[]    = $file;

      }
   }
}

foreach($directories as $directory){
   echo '<li class="folder">'.$directory.'</li>';
}
foreach($files_list as $file_list){
   echo '<li class="file">'.$file_list.'</li>';
}
