oop thingie

ok first of all i admit i am complete new to OOP. Secondly didnt write this script. but there is my problem i declare a class say dog. dog uses a constructor that has a few extra unassigned arrays. laster i declare a new instance of dog in another class (pets) i invoke the constructor and all is well with a few empty arrays as part of my object. but how can i put information in these arrays? can i do it through pet? for example can i make a member function in pet that goes soemthing like this - function wekkcount($id, $newpets) { $i=0; while($newpets[$i]) { $this->dog[$id]->lostpets[$i] = $newpets[$i]; $i++; } where this refers to class pets and dog is an instance of dog? i have been trying to all day and even though i know for sure $newpets has information in it. i always have an empty array in pets->dog->lostpets. i am starting to believe maybe i just cant do it. or maybe there is soemthing stupid i am missing?
