Read the page. If it works in all versions except 7.0.8 then there's nothing to do because that's an old version and we're on 7.0.17 now. Can't go back in time. Though I still doubt this problem actually exists. ------------------------------------------------------------------------ [2017-03-30 16:32:38] damianboni at gmail dot com Issue occurs on version 7.0.8 , you're testing it on 5.6.X ------------------------------------------------------------------------ [2017-03-30 16:07:08] spam2 at rhsoft dot net > always get true with an exception to 7.0.8 reported for PHP Version: 7.0.17 so what does that mean? "I tested the below script on different version of PHP and always get true with an exception to 7.0.8" - m yunderstanding is that this only happens on the Ubuntu build, not with a recent PHP release and so is not a current upstream pug? ------------------------------------------------------------------------ [2017-03-30 16:04:33] requinix@php.net Seems to working fine. https://3v4l.org/uKiR6 You tried with that *exact* script? Are you using any zend_extensions? Any difference with opcache enabled and disabled? ------------------------------------------------------------------------ [2017-03-30 15:55:22] damianboni at gmail dot com Description: ------------ Tested on PHP7.0.8 ubuntu 16.04.3 @ 2017-03-30 isset() is incorrectly retuning false (should return true) when checking array key that has its value set to boolean. I tested the below script on different version of PHP and always get true with an exception to 7.0.8 Test script: --------------- Code: $params['entry']['attributes'] = array( 'enabled' => true ); var_dump(isset($params['entry']['attributes']['enabled'])); $whatIsGoingOn = $params['entry']['attributes']['enabled']; var_dump(isset($whatIsGoingOn)); var_dump(array_key_exists('enabled', $params['entry']['attributes'])); Output: bool(false) bool(true) bool(true) Expected result: ---------------- bool(true) bool(true) bool(true) Actual result: -------------- bool(false) bool(true) bool(true) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74344&edit=1
