bug #47358 -- unexpected behaviour

hi, could someone please enlighten me, why bug #47358 http://bugs.php.net/bug.php?id=47358 was closed as "bogus"? the bug was reported for 5.2.9 but applies to 5.3.x and 5.4.x as well. i can't see, why glob should return 'false' if the search pattern does not match, even though if the directory being searched in is valid compared to the open_basedir settings: php -r "var_dump(glob('/tmp/*.php'));" array(0) { } vs. php -d "open_basedir=/tmp/" -r "var_dump(glob('/tmp/*.php'));" bool(false) i fail to understand, why the second one is expected behaviour. i stumbled over this when playing with the fat free framework, which uses quite a lot of glob statements in its autoloader, in a shared hosting environment. thanks in advance, harald
