I have mysql database for internal computer evidence and I store IP as
unsigned numeric value. It is very good for computing network ranges and
so on. But PHP do not support unsigned integer. So when I store values
to doatabase, I must convert it to string with sprintf. When reading it,
I get a string value with 10-digit number, bigger than maxint. I need to
convert it to signed int and work with it as a number (for making binary
arithmetics). I have discovered no way how to do it. Intval() or (int)
type conversion returns maxint. Converting it in mysql is anoying too,
because mysql cant do signed 32-bit int type conversion, only 64 bit.
