7.3. Destroying an Object
Problem
You want to eliminate an object.
Solution
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
Discussion
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.
