ID: 28528 Updated by: [EMAIL PROTECTED] Reported By: liamr at umich dot edu -Status: Open +Status: Bogus Bug Type: Directory function related Operating System: linux 2.4.24 PHP Version: 4.3.6 New Comment:
Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. The problems seems to a memory corruption elsewhere as the libc function glob() does not return a valid pointer to a list of matching entries. In this case PHP has no way of determining whether or not the data returned is valid.
