Deleting objects

So far our objects have been automatically destroyed at the end of the script they were created in, thanks to PHP's automatic garbage collection. However, you will almost certainly want to arbitrarily delete objects at some point in time, and this is accomplished using unset() in the same way as you would delete an ordinary variable.

Calling unset() on an object will call its destructor before deleting the object, as you would expect.
