Updating Objects

[scottybwoy]

Is there a function that can search an objects for a piece of data to append some information to it?

 

i.e I have a object that has this structure

 

$obj->cat#->sub_cats->sub_cat#->products->product_name

 

I have another object with a number of product_names for all the sub_cats for a specified cat #.  How can I search for the product_name in the original object to update it with the additional data in the second object?

 

Thanks, by the way I'm using php4
