Hmm. I'm already using an abstraction layer; Net_Socket from PEAR. I had to modify the
readLine method to read a byte at a time until it encounters \n to workaround the
fgets bug.

No it doesn't.

Sorry - I somehow missed the unset.
However, unset just removes the variable from the symbol table - try using $page =
null instead.
I am in the process of working on a file abstraction for this stuff, so it will be
rewritten.
The wierd thing is that I really can't see why fgets would behave differently from
fread. Maybe I haven't looked hard enough.
Please let me know if $page = null works around the problem for now.

No, that's what the unset is for.
Anyways, here's memory statistics.
On loading script one: 3740kb RAM used after two iterations (RAM should not increase
above this level).
After 5 minutes: 4130kb.
Cf script two: 3752kb RAM used initially, and 3752kb after 5 minutes.
These statistics aren't especially dramatic, but in other conditions it can be
catastrophic.
Regarding fclose, no this doesn't help.
There is a problem with fgets but not fread.

Um, yes, the memory usage increases because you are appending an infinite number of
copies of the google page to your $page variable.
I can't see any leak in PHP - no leaks are reported by the memory manager.
Can you give me more information about how the memory usage increases, and what you
would expect it to be?
Could you try explicitly fclose()ing your $fps too - you might find it useful in
reducing memory cost.
--Wez.
