- PHP 5 introduces a destructor concept similar to that of other
- object-oriented languages, such as Java: When the last reference to an
- object is destroyed the object's destructor, which is a class method
- named <function>__destruct</function> that receives no parameters, is
- called before the object is freed from memory.
