Ok, I see. Thank you all for replying. I guess there are a lot to be
learned for me now.
I'm actually trying to learn C and put it in use of writing PHP
extensions. Because from years of working with PHP, I start to feel that
PHP might be a bit weak for performance sensitive tasks.
Well, it's a long way ahead, and I'd better get going now. Thanks again
for the help, and I'll send more 'spam' if I've got problem with PHP and
Zend in the future. :D

Still, this is a really strange experience. Where are those characters
come from? Shouldn't it be a clean array when I first created them?
Anything related to the zval structure?
This is not PHP-related. When you *define* a variable, it has no
content, you have to initialize it. The characters you got are from the
uninitialized space you used in the stack.
C won't initialize variables for you as it would be a waste of time in
the case you already initialize it with a non-NULL value.
Anyway as this is not PHP-related, I suggest this discussion to be
continued outside of the PHP internals mailing list, if you have any
question, I can probably give you some pointers to good documentation,
just need to understand what you are trying to do.
Best regards,
Mark
