Assert is not working in PHP. So simple. What am I doing wrong?

assert, php

Solution

It looks like assertions are OFF out of the box on 7.0. In my php.ini file zend.assertions was set to -1, which means they are ignored. I have changed the setting to 1.

[Assertion]
; Switch whether to compile assertions at all (to have no overhead at run-time)
; -1: Do not compile at all
;  0: Jump over assertion at run-time
;  1: Execute assertions
; Changing from or to a negative value is only possible in php.ini! (For turning assertions on and off at run-time, see assert.active, when zend.assertions = 1)
; Default Value: 1
; Development Value: 1
; Production Value: -1
; http://php.net/zend.assertions
zend.assertions = 1

The script now works as expected.

php x.php

Hello
PHP Warning:  assert(): assert(false) failed in /home/ubuntu/code/x/test/x.php on line 8

Problem

It's like assert isn't even being called. I am confused. The version ``` php -v PHP 7.0.11-1+deb.sury.org~xenial+1 (cli) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies with Zend OPcache v7.0.11-1+deb.sury.org~xenial+1, Copyright (c) 1999-2016, by Zend Technologies ``` The script: x.php ``` <?php print ("Hello\n"); assert_options(ASSERT_ACTIVE,true); assert_options(ASSERT_BAIL,true); assert(false); assert(true); print ("Bye\n"); ``` when I run it ``` php x.php Hello Bye ``` I would have expected the program to terminate with an exception. Am I going crazy?
