New Comment:
PHP's internal integer type is a signed long. with 32bit 2336962885 is out of
range. While properly printing it gives you the correct value:
php -r 'printf("%u", -1958004411);'
2336962885
Besides that there are projects for large file support (while that's not as relevant on most
64bit systems [except windows 64bit] these days where it works out of the box) and for aritrary size
"integer" types. But both projects aren't trivial due to the wayand amount of 3rd
party libraries PHP interacts with. If you have a constructive proposal/solution for those
we're more than happy to implement those, though.

hmm, feature is something missing in a product, however this one is a plain bug.
perl, python, 3-line c program, stat, ls they all return correct size. what is wrong with php to
return correct filesize?
this is strace cut:
---
stat64("/home/data/bigfile.data", {st_mode=S_IFREG|0644, st_size=2336962885, ...}) = 0
write(1, "-1958004411\n", 12-1958004411
---
it's clear that from system level correct size is returned. it's a matter of using correct
types to store and return the value from php perspective

LFS is not supported by default. See other feature requests about this issue.
