Old Summary: file_exists doesn't work with 2G+ files
Reported By: [EMAIL PROTECTED]
Status: Feedback
Bug Type: *Directory/Filesystem functions
Operating System: Linux
PHP Version: 4.0.5
New Comment:
If the OS is compiled and installed on a 64 bit system,
or with large file support (read: kernel, libc, others)
then calls to stat() and friends return 64-bit structures. You don't
need to call stat64 expressly. A stock RedHat-7.2
box isn't 64bit compliant unless it's compiled that way.
The VCWD_STAT macro uses stat(path, buff), not
stat(path, mode). I've had a look at stat.h and see
the references to stat64(path, buff) if large file
support is defined, but I'm in a little over my head
here, so I bow to [EMAIL PROTECTED]'s mastery of php
internals. :)
I don't have access to a 64bit box or fs to confirm, so I guess I
jumped the gun on this one, but IMHO, this isn't a
PHP *bug*.
Sorry for the confusion.

I believe I had found the reason of this bug.
file_exists function ultimately calls VCWD_STAT function defined in
TSRM/tsrm_virtual_cwd.h. However, the VCWD_STAT function is only a
macro for stat(path, mode), and under Linux, you need stat64 for 64 bit
file stats operations.
hmm, and all the file I/Os under PHP right now do not support 64 bits.
This is bad...

Can not seem to find the RPM(php-4.1.1) for Redhat 7.2. :(
There is no build environment on testing machines.

and then again, can you please test with a more recent PHP release?

Where can I (and how do I) get the source code to file_exists function?

Actually, I do have a 4Gig file on the file system. (Since we used the
64bit file operation for our software on all our file I/O)
