Description:
------------
test is simple:

print_r(glob("/var/www/*"));


Always returns empty array.
____________________________

Yes, I know this is strange, yes I have search whole web and no solution yet.

Problem is probably related to OS, because other server (also linux lenny) work OK on the same apache2 and same php5 module.

I have made simple command line test:

sudo -u www-data php5 -c /etc/php5/apache2/php.ini -r 'print_r(glob("/var/www/*"));'


And this is working OK.
My apache2 has no strange modules, this is normal web server.

My system:
php5:  5.2.6.dfsg.1-1+lenny9 
kernel: 2.6.8-2-386
libc6:  2.7-18lenny6 
apache: apache2  2.2.9-10+lenny8 

No special file system security on OS, /var/www is 777, default apache2 security settings.

This problem is VERY rare, but Im not the only one:

same problem here:
http://forums.gentoo.org/viewtopic-t-826894-start-0.html

Any suggestions?
PLEASE HELP!

Test script:
---------------
print_r(glob("/var/www/*"));

Expected result:
----------------
glob() should return array of files

Actual result:
--------------
empty array, no errors

Add error_reporting(-1); ini_set('display_errors', 'on'); to your script before calling glob() and see if any errors are generated.

Also, are you using SELinux by any chance?

After adding:
ini_set('display_errors', 'on');

I have no errors, I also try:

error_reporting(E_ALL|E_STRICT);
ini_set('log_errors',1);
assert_options(ASSERT_BAIL,1);

same thing: no errors, empty array

I have try to open this dir and list files by other way, eg. opendir and this way everything is OK and code work as expected.
