Status: Bogus
Bug Type: Safe Mode/open_basedir
Operating System: FreeBSD 7.1
PHP Version: 5.2.9RC1
New Comment:
"an empty array if no file matched" is what i see in the manual.
but this returns error, and not an empty array()
glob("/path/allowd/in/open_basedir/nonexitentfile.*");
I can understand why a system glob call returning no files, and a call
returning only nonallowed files has to be treated the same.
But im to dumb to see the logic in treating both as errors instead of
"no files matched", especially because that breaks existing code.
And treating it as "no files matched" doesnt break anything.
Please enlighten me if im wrong, and ill put on my pointy hat and sit
in the corner for the rest of the day.
But now i have link i can give the users telling me my servers doesn't
work right. So i guess i can live with that.

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
The function is documented to return FALSE on error. There is no
problem
here...

Description:
------------
glob() cant be used directly in foreach when open_basedir is set.
i found #41655 which is about the change causing this, and a few other
closed tickets with "not a bug" as answer.
But that change destroys foreach(glob("nonexistent*") as ... when using
open_basedir, and the following comment in dir.c states that should be
usable.
/* Some glob implementation simply return no data if no matches
were found, others return the GLOB_NOMATCH error code.
We don't want to treat GLOB_NOMATCH as an error condition
so that PHP glob() behaves the same on both types of
implementations and so that 'foreach (glob() as ...'
can be used for simple glob() calls without further error
checking.
*/
As far as i can tell the right thing to do would be to return an empty
array both when using glob("/etc/hosts") and glob("/etc/nonexistent")
when open_basedir is used. Or what am i missing?
Ive been using the following patch, and as far as i can tell its not
possible to check if a file exists when open_basedir is used, and
foreach(glob("nonext*")) works correctly.

Reproduce code:
---------------
set open_basedir /documentroot
open /documentroot/test.php with the following content
<? var_dump(glob("nonexistent*")); ?>
Expected result:
----------------
array(0) {
}
Actual result:
--------------
bool(false)
