Re: Problems with filesize() and large files

Just figure out what the limits of 32-bit integers are. It might be enough to do something like $num = INT_MAX + abs( INT_MIN - filesize(bigFile) ); I'm not sure if that's the right math, but I hope you get the idea. If memory serves, what's happening is that the 32nd bit (which represents the sign- 0='+', 1='-') is getting flipped because you're trying to store 8 bits of data in 7 bits of space.
