is_dir() throws a Warning: Unable to access ....

But only when safe mode is turned on, instead of just returning false.

If the dir doesn't exist it throws this warning ..but only in safe mode, instead of simply returning false.

What is the full error message?
 [2002-11-18 15:56 UTC] half-dead at nospam dot net 
is_dir("nonexisten directory.....");

result:

Warning: Unable to access "nonexisten directory....." in "whatever.php" on line "xx"

Okay, it looks like this is fixed in CVS. Can you try the windows snapshot @ http://snaps.php.net/~edink/php-4.3.0RC1-Win32.zip ?

Nope not in safe mode at least, now i simply get a ref to the php doc page with the warning (4.3RC1):

is_dir("non existing directory...");

Warning: is_dir() [http://www.php.net/function.is-dir]: Unable to access "non existing directory..." in "whatever.php" on line "xx"

--------
Again, this only happens if safe mode is turned ON

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

I don't get it.  Someone reports a bug, it's tested in latest PHP version as asked, problem still exists ... and now it's marked as bogus?

Why doesn't this simply return boolean false?  Where is this behavior documented?  Reopening...

My mistake, I misread the whole issue here..and forgot that is_dir() is not supposed to output any errors. :)

Anyway, the problem is in php_checkuid() which outputs
the error. I guess we need to put some extra parameter for it to not output errors..
 [2002-12-01 19:52 UTC] sniper@php.net 
forgot to update the version and OS..

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.
