Hi:
I think what I was done is try to describe a image, that we can make
follow codes more simple:
if (strncmp(substr("num_suffix", 0, -5), "suffix", 5) == 0) {
echo "they have the same suffix";
}
yes, there is must something not good in my patch, but I think I
can tweak it as you wish.
the only thing I want you to accept is : " should this behavior is
more make sense for some occassion?"
thanks
