> 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?

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?

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)
