Objects are automatically destroyed when a script terminates. To force the destruction of an object, use unset( ):
$car = new car; // buy new car ... unset($car); // car wreck
It's not normally necessary to manually clean up objects, but if you have a large loop, unset( ) can help keep memory usage from spiraling out of control.
PHP 4 doesn't have destructors, however Zend Engine 2 supports them with the _ _destruct( ) method.
