No, I don't think so.
If you're trying to outsmart the cache jumping from/into different
directories and doing the stat() using *relative* path - this is not
PHP problem (and it can be easily solved with clearstatcache(), but
I've already told you that).

Don't you think that the key that is used to access the
cache should be the _full_, _absolute_ path instead of
just the string passed to file_exists()?
Current solution doesn't guarantee proper results - how do
you know whether the code you call doesn't change into
some other directory and stats() eg. "foo" won't interfere
with the other piece code checking for "foo" existence in
other directory? The only way to do such checks reliably
is to call clearstatcache() _each_ _time_ what makes the
cache useless. At least for me. I think it's a design
error.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
Use clearstatcache() to clear the cache.

I made mistake in the code - here is the corrected
version:
touch("foobar");
echo file_exists("foobar") . "\n";
mkdir("foodir");
chdir("foodir");
echo file_exists("foobar") . "\n";

Description:
I find caching of file_exists() and similar functions
causing strange results - as presented by attached code,
it might cause unexistent files to... "exist" :).
Reproduce code:
---
[EMAIL PROTECTED] file_exists]$ ls
file_exists.php
[EMAIL PROTECTED] file_exists]$ cat file_exists.php
Expected result:
[EMAIL PROTECTED] file_exists]$ php file_exists.php
1
Actual result:
--
[EMAIL PROTECTED] file_exists]$ php file_exists.php
1
1
