pleae don't break code like this which is a useful case for access 
directly a array field returned from a function and so makes this to a 
one-liner without check the result

public function GetMaxSort(): int
{
  return (int)mysqli_fetch_row($this->cl_api->db->query("select 
SQL_NO_CACHE max(hsort) from {$this->cl_api->sql_prefix}main", 1))[0];
}
