function_exists - find the file containing a given function in an object string function_exists( string str, object ob ); Return the file name of the object that defines the function 'str' in object 'ob'. The returned value can be other than 'file_name(ob)' if the function is defined by an inherited object. 0 is returned if the function was not defined. Note that function_exists() does not check shadows, or functions that cannot be called from outside the object. See also: call_other Tim Hollebeek Beek@ZorkMUD, Lima Bean, IdeaExchange, and elsewhere
