Question

function deletefiles($directory)
{
    $folder = glob($directory);  // <--error on this line.
    foreach($folder as $file)
    {
        if(is_dir($file)) 
        { 
            deletefiles($directory);
        } 
        else 
        {
            unlink($file);
        }
    }
    if(is_dir($directory))
    {
        rmdir($directory);
    }
}

That’s the code causing the error. The function is supposed to delete all files and subdirectories of a specified folder. Each folder only contains maybe 5 maximum subfolders.
This function worked when there was only files in the folder. Any insight would be greatly appreciated.

There are 2 places needed to fix.

function deletefiles($directory)
{
  $folder = glob($directory . '/*'); // <-- here
  foreach($folder as $file)
  {
    if(is_dir($file)) 
    { 
      deletefiles($file); // <-- and here
    } 
    else 
    {
      unlink($file);
    }
  }
  if(is_dir($directory))
  {
    rmdir($directory);
  }
}
