Description:
------------
PHP evaluates an undefined constant as true, whereas it evaluates an
undefined variable as false.

Reproduce code:
---------------
<?= TEST ? '1' : '0' ?><br />
<?= $test ? '1' : '0' ?><br />

Expected result:
----------------
Notice: Use of undefined constant TEST - assumed 'TEST' in test.php on
line 1
0

Notice: Undefined variable: test in test.php on line 2
0

Actual result:
--------------
Notice: Use of undefined constant TEST - assumed 'TEST' in test.php on
line 1
1

Notice: Undefined variable: test in test.php on line 2
0
