Objects in PHP

In standard programming languages, there are two choices to use previous code inside of a new object, with differing design implications; A/ Objects CONTAIN other objects B/ Objects INHERIT other objects. Are both used in PHP? other questions in PHP- 1/ How is an object instantiated inside another object definition? 2/ Is object inheritance 'flat' in php? i.e. object 'A' has function AF1, Object 'B' has function BF2 now, B extends A{} B object calls $this->AF1 with no scope resolution operator?
