Re: [chiPHPug-discuss] troublesome PHP behavior

[Trevor O. <tr...@gm...>]

I'd probably use preg_match_all, or your method, depending on what sort of
data i was parsing.

Here's some funny behavior I saw yesterday, but is also as intended.

One expects x%10 to always return a number between 0 and 9 inclusive.
However, -16%10 is -6.
The answer makes sense (-16/10 = -1r-6) but I kind of expected it to just
add another 10 onto it, so it became 4.
For my expected behavior, I had to say ((x%y)+y)%y
