断言在php中不起作用。这么简单。我做错了什么?

断言在php中不起作用。这么简单。我做错了什么?,php,assert,Php,Assert,好像assert甚至都没有被调用。我很困惑 版本 :~/code/x/test$ 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

好像assert甚至都没有被调用。我很困惑

:~/code/x/test$ cat x.php
<?php

print ("Hello\n");

assert_options(ASSERT_ACTIVE,true);
assert_options(ASSERT_BAIL,true);

assert(false);
assert(true);

print ("Bye\n");
我本以为程序会以异常终止。我疯了吗?

谢谢你,真愚蠢

看起来断言在7.0上是现成的。在我的php.ini文件中,zend.assertions被设置为-1,这意味着它们被忽略。我已将设置更改为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
脚本现在按预期工作

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

在PHP7.0.12中,我得到一个
警告:assert():assert(false)失败
assert在升级到7.0.12的PHP7检查中更改了一点,但输出是相同的
