I was thinking about a similar solution, but if the file exceeds the 4
Gigabyte limit, the solution won't help anymore. And it wil be a matter
of time to exceed this limit.
But I'm afraid there is no other solution for this.

Subject: Re: [PHP] Problems with filesize() and large files
Just figure out what the limits of 32-bit integers are. It might be
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
sign- 0='+', 1='-') is getting flipped because you're trying to store 8
of data in 7 bits of space.
