The javascript getData() will have to launch a php script to get the
data again OR you can simply sort the data yourself using sort().
Here's another idea using jQuery:

Well.. count me among those staring. I just don't get those type of
things until I see them actually work.
My "logic" works the other way -- when presented with a logic problem, I
come up with a solution that works the way I think and I always to solve
the problem presented. Perhaps my solution isn't as clever nor as
cryptic as others, but it's always easier to read and understand.

I'm with you Tedd. I'm forever cussing myself when I use a super clever trick to
solve a logic problem and then later can't figure out how the damn thing worked
even though I documented it.
Incidentally, about formatting scripts, one of the reasons I like phpEdit is
that it has a terrific code beautifier. You can set it for phpDoc or Pear
rendering. And, it auto indents, etc. as you enter stuff.

+1
I've never had other coders looking over my shoulder, and I agonized for
years over whether my logical solutions were the "best" approach. Now I
just code and take pride in the fact that I can understand what I did
later (mostly).

I think as long as the code is readable, and doesn't have any glaringly
obvious issues (I've seen people re-writing built in PHP functionality
because they didn't know the built-in function existed) then it should
be OK. Add comments to aid any areas where you think you might forget or
other people might not easily understand what is happening.
Don't get me wrong, clever ideas are nice, and sometimes with the right
comment they just work beautifully. Just occassionally though something
is done in such a neat clever way, that in the future when it comes time
to extend the system, this neat clever idea is actually a hindrance and
causes extra work because it has to be re-written a 'less-clever' but
more flexible way!

That reminds me of a story. I once wrote what was almost an RPG (RPG--
the language, not the game) interpeter under FoxPro to handle incoming
EDI traffic and update invoicing, etc. The big problem with EDI is that
no one follows the standards properly, so every vendor tendering an
invoice did it differently. So you needed a database driven system which
would selectively make decisions based on each line of incoming EDI
content. Worked great, and when a new vendor came along, you just
analyzed their transactions and populated some more records in the
database to handle that vendor's transactions. I know, it sounds
obscure, but it made perfect sense at the time.
Shortly after that, I left that company. I documented the system, and it
worked fine, but it was hard to wrap your wits around how it worked. And
I just know the next coder on that account was cursing me day and night
for writing that system.
Anyway...

Hi All,
Is there an option in PHP to change the behavior of NULL in PHP functions ?
Now PHP uses NULL as a 0 (zero) for arithmetic, for example:
NULL + 6 = 6
NULL * 6 = 0
NULL / 6 = 0
6 / NULL = Division by zero
What I need is the same behavior as #N/A (or =NA()) in Excel, where:
#N/A + 6 = #N/A
#N/A * 6 = #N/A
#N/A / 6 = #N/A
6 / #N/A = #N/A
because arithmetic operations with "Unknown" operands should result to
"Unknown" ...
TIA, Cor
