Hi All,
Just to annoy the hell out of you, another thing that has been on my mind
for a while:
I love the foreach ($ar as $k = $v) { ... } construct and use it all the
time. However, I read somewhere that foreach actually uses a copy of $ar
instead of the array itself by reference. Wouldn't it

Somewhere i also read that one can save a lot of memory by destroying
variables. Is that done with unset, setting it to null or something
similar?
unset()
So, i take there is no garbage collection in php? I've never
actually looked at the c source code of php. Maybe
PHP does have garbage_collection, and it's crucial in long-running CLI scripts.
Per is right, though, in that if your web-page Apache PHP script needs GC, you
are doing something terribly wrong.
It is not as aggressive/thorough as, say, the Lisp GC, but it's there.
ymmv
