Create folder not working!

1

I am trying to create a new folder in PHP, but when I try using the below code, it doesn’t work. None of the codes I tried worked!

Any help would be appreciated!


  //Get folder name from form string
$_SERVER['QUERY_STRING'];
$folderName = $_POST['client'];

//Path to where you want to create the new folder
$path = "/clients/";

//Complete path to new folder
$d = $path . $folderName;

chmod($d, 0700);

echo "Folder " . $d . " has been created.";
  }
