The "Object ..." string is the result of PHP converting an object to a
string. The id # in PHP5 is a new feature. Internally, the Zend 2
engine keeps track of all objects in an array. An object's id is its
place within that array.
The object id is useful for debugging purpose. It also give you a way
to use objects as keys to a hash table.
