how check method exist

I love your response. It's like a puzzle. Here's how you use it (and this has nothing to do with OOP.. it's just a function that says whether the given object has the given method).

Code:

class Frog {

   function Frog()
   {
      print method_exists($this, 'lick') ? 'Frog can lick.' : 'Frog cannot lick';
   }

   function lick()
   {
      print 'Licked.'
   }

}
