To initialize an object, you use the new statement to instantiate the object to a variable.
For a full discussion, please read the section Classes and Objects.
If an object is converted to an object, it is not modified. If a value of any other type is converted to an object, a new instace of the stdClass built in class is created. If the value was null, the new instance will be empty. For any other value, a member variable named scalar will contain the value.
