Edit report at https://bugs.php.net/bug.php?id=71592&edit=1 ID: 71592 Updated by: cmb@php.net Reported by: anrdaemon at freemail dot ru Summary: External entity processing never fail regardless of handler return code -Status: Open +Status: Verified Type: Bug Package: XML related Operating System: Windows PHP Version: 5.6.18 Block user comment: N Private report: N New Comment: This part of the documentation refers to libexpat based ext/xml. For libxml2 based ext/xml, the external entity reference handler is effectively a void function. Not sure, whether libexpat's behavior could be implemented with libxml2.
