    If it's /tmp, it's /tmp.  The leading slash indicates that it's in
the filesystem root.  However, if it's just tmp, then it could - and
probably is - under the client's home directory.  Unless they're
chrooted; then it could be displayed as /tmp, but would actually be
virtualized by the OS, where /tmp isn't really /tmp, but could be

    Confusing?  Sure.  Off-topic for the list?  Sort of, but that's
easy enough to change.

    Since you can't use get_sys_temp_dir() on 4.3.10, you should
instead see if $_ENV contains an array key for TMP, TMPDIR, or TEMP.
Or, if you'd rather, you can use getenv('TMP') and the like.  It
doesn't mean that you'll get any useful information back (or anything
at all, necessarily), but it's another thing to try when using such an
antiquated version (I believe it was released at the end of 2004).
