Undefined variable and Call to a member function on a non-object


Recommended Posts

   I have the situation shown below in the code:
if(//condition is met)
{ $val = new Val();
  $valon = $val->check($_POST, array(.........));
{ $use = new Use();
//check() and passes() both belong to class Val
public function check($source, $items = array())
{ ......................
  return $this;

I get the following warning and error:

Notice: Undefined variable: valon
Fatal error: Call to a member function passes() on a non-object

I can't see anything wrong with the code. check() returns an object of class Val which is assigned to $valon, $valon then calls a member function of class Val. Could you please help. Please let me know whether to include further code.

    if ($valon -> passes())
        $use = new Use();
        // ...
