Status: No Feedback
Bug Type: *Directory/Filesystem functions
Operating System: Windows XP SP1
PHP Version: 4.3.7
New Comment:
Same behaviour here, on winxp with php4 and debian with php5, seems
conceptually wrong, I would report the exact versions but it would seem
this behaviour is constant on every version. Where is the sanity in
truncating a file to 0 bytes if the code attempts to copy it over
itself? Should preferably check for equivalent filepaths and not
perform the copy function, or at least report a warning that the files
were the same, both command line copy and cp (win and linux) do that.

Reproducible with Windows and Linux, looks like platform independant:
copy("/tmp/sess_1151d8174614735db903faef81b4fae0","/tmp/sess_1151d8174614735db903faef81b4fae0");
Actual result:
--------------
File changed to 0 bytes.

How come no one is looking into this? It's reproducible on Linux as
well.
copy("test.txt", "test.txt") -> 0 bytes
You can't avoid this problem just by checking the filename, since one
could be a symlink pointing to the other. It would introduce platform
dependency as well (case-insensitivity on Windows).
