ID: 46055 Updated by: iliaa@php.net Reported By: felipe@php.net -Status: Open +Status: Bogus Bug Type: Unknown/Other Function Operating System: * PHP Version: 5.3CVS-2008-09-11 (CVS) 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. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. Its an internal bug of the tidy library, it lacks basic checks to ensure that the provided struct is containing data.
