Edit report at https://bugs.php.net/bug.php?id=73875&edit=1 ID: 73875 Comment by: vedad at kajtaz dot net Reported by: vedad at kajtaz dot net Summary: assert() evaluated despite runtime assert_options(ASSERT_ACTIVE, 0); Status: Open Type: Bug Package: Scripting Engine problem Operating System: FreeBSD 10.1 PHP Version: 7.0.14 Block user comment: N Private report: N New Comment: Expressions are allowed in assertions since PHP 7.0: > 7.0.0 assert() is now a language construct and not a function. assertion() can now be an > expression. That being said, it is either undocumented or plain wrong that the expression be evaluated despite asserts being disabled.

I understand one should use zend.assertions in PHP 7+, yet IMHO this is either a documentation bug, or a misbehavior.
