导读:这就像断言甚至没有被调用.我很迷惑. 版本 :~/code/x/test$php -vPHP 7.0.11-1+deb.sury.org~xenial+1 (cli) ( NTS )Copyright (c) 1997-2016 The PHP GroupZend Engine v3.0.0,Copyright (c) 1998-2016 Zend Technologies with Zend OPcache v7.0.11-1+deb.

版本 :~/code/x/test$php -v PHP 7.0.11-1+deb.sury.org~xenial+1 (cli) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0,Copyright (c) 1998-2016 Zend Technologies with Zend OPcache v7.0.11-1+deb.sury.org~xenial+1,Copyright (c) 1999-2016,by Zend Technologies 剧本 :~/code/x/test$cat x.php <?php print ("Hellon"); assert_options(ASSERT_ACTIVE,true); assert_options(ASSERT_BAIL,true); assert(false); assert(true); print ("Byen"); 当我跑它 :~/code/x/test$php x.php Hello Bye 我原以为程序会以异常终止.我疯了吗?
谢谢RiggsFolly.
看起来像断言在7.0的开箱即用.在我的php.ini文件中,zend.assertions设置为-1,这意味着它们被忽略.我已将设置更改为1. [Assertion] ; Switch whether to compile assertions at all (to have no overhead at run-time) ; -1: Do not compile at all ; 0: Jump over assertion at run-time ; 1: Execute assertions ; Changing from or to a negative value is only possible in php.ini! (For turning assertions on and off at run-time,see assert.active,when zend.assertions = 1) ; Default Value: 1 ; Development Value: 1 ; Production Value: -1 ; http://php.net/zend.assertions zend.assertions = 1 该脚本现在按预期工作. :~/code/x/test$php x.php Hello PHP Warning: assert(): assert(false) failed in /home/ubuntu/code/x/test/x.php on line 8 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
