Trying to clone a stdClass

How to "clone" a php POSCO (Plain Old StdClass Object) via cast chaining:

$cloneObj = (object) (array) $myPOSCO;
var_dump($cloneObj == $myPOSCO); // true
var_dump($cloneObj === $myPOSCO); // false

When cloning an object, all the object properties are simply copied over to a new instance of the object. In effect this:

$cloned = new stdClass;
$cloned->date = $object->date;

As you probably know, assigning an object to another variable does not duplicate the object; there's still just one object, now with two references to it.

To deep-clone an object you need to implement a custom class with the __clone method and manually clone any child objects of it.
