#47358 [Opn->Bgs]: glob returns error, should be empty array()

ID: 47358 Updated by: iliaa@php.net Reported By: php at guggemand dot dk -Status: Open +Status: Bogus Bug Type: Safe Mode/open_basedir Operating System: FreeBSD 7.1 PHP Version: 5.2.9RC1 New Comment: 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... Previous Comments: ------------------------------------------------------------------------ [2009-02-11 08:12:10] php at guggemand dot dk 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. http://gugge.dlx.dk/ting/php5-patch-dir.c 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) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47358&edit=1
