Description:
------------
It would be nice if the PHP documentation included notes on the function pages for functions that fail on 32bit servers and files larger than 2GB.

For example, 

is_file
file_exists
realpath (as of php 5.3.0)
filesize
(and a bunch of others)

For example, the filesize function includes this note:

Note: Because PHP's integer type is signed and many platforms use 32bit integers, filesize() may return unexpected results for files which are larger than 2GB. For files between 2GB and 4GB in size this can usually be overcome by using sprintf("%u", filesize($file)). 

It would be very helpful if all the builtin functions that suffer this fate with large files on 32bit systems had similar official notes.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

I forgot to tag the revision with this bug's ID, so the relevant revision is 
r317928.

Let me know if I missed any functions that are affected by this limitation.
