Explicit object cloning
In order to clone an object you have to use the clone keyword. You may declare a __clone() method which will be called during the clone process (after the properties have been copied from the original object).

class MyClass {
function __clone() {
print "Object is being cloned";
}
}
$obj = new MyClass();
clone $obj;

Class constants
Classes definitions can now include constant values, and are referenced using the class.

class MyClass {
const SUCCESS = "Success";
const FAILURE = "Failure";
}
print MyClass::SUCCESS;
