Bug Type: Bug
Bug description:weak logic operator are buggy
Description:
------------
see test script. Seems like the weak logic operators do not have any
effect.
My PHP version is 5.4.7
Was already mentioned in https://bugs.php.net/bug.php?id=46530&edit=2
Test script:
---------------
$a = false or true;
var_dump($a); //boolean false
$a = true or false;
var_dump($a); //boolean true - that's ok
$a = true xor true;
var_dump($a); //boolean true
$a = false xor true;
var_dump($a); //boolean false
$a = true and false;
var_dump($a); //boolean true
Expected result:
----------------
//or
boolean true
boolean true - this one worked as expected
//xor
boolean false
boolean true
//and
boolean false
