Hi,

I've read a few threads in this group recently, discussing garbage
collecting and unsetting variables and the likes. Concerning memory usage in
PHP: what is good practice, i.e. what should I be worried about, or what
kind of garbage collecting of my own should I consider?

Would it be good practice for instance to unset or set variables to NULL
immediately when I don't need them anymore. Also: do variables dissapear
from memory when out of scope? I would hope so.

Finally my gutfeeling tells me, that when a script stops, the memory that
was taken up by the script would clear instantly, but that doesn't always
seem the case considering what some people here have mentioned about it.
What's the real deal?

Thank you for any tips / advice on the matter.
