If the developer creates a copy of an object using the reserved word clone, the Zend engine will check if a
__clone() method has been defined or not. If not, it will call a default __clone() which will copy the object's
properties. If a __clone() method is defined, then it will be responsible for setting the necessary properties in the
created object. For convenience, the engine will supply a function that imports the properties of the source object, so
that the programmer can start with a by-value replica of the source object and only override properties that need to
be changed. [18]
