when does data get released?

[handcraftedweb]

When a (PHP) web page is requested, the PHP code is compiled and executed, the page is constructed and served.

After that, are the data structures created by the PHP in that page released automatically, or do I need to manage that with myself? (I'm planning on doing OOP style programming, lots of classes and objects.)

Thanks,
...Mike

the are 'released' when the script finishes.
