Re: [PHP] 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.

The problem is that the integer returns the size in byte as an integer. If the integer is too big, it returns an negative value. Is it possible to extend the integer to 64 bit ? Or any other solution, to solve this problem ? Example: C:\php423\phpphp -q c:\devel\filesize.php int(-834864026) Which checks the size of a 3 Gigabyte file.

RE: [PHP] Problems with filesize() and large files
Yep, 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.

Hi Kurt, not pretty, but what about using the CLI tool ls with an exec() call? Timo Am Dienstag den, 10.
