Description:
------------
When I try this script it should at my point of view return 0 instead of 1 ?
am I mistaken ?

Test script:
---------------
<?php
if (false && true?"1":"2") {
	echo 1;
} else {
	echo 0;
}
?>

Expected result:
----------------
0

Actual result:
--------------
1

seems to be an error on my side... I omit the priority of operators

The example given returns the correct result. 
The ternary operator is would always return a string which is always truthy. 
Even the integers 1 or 2 would evaluate as true; however, 0 would be false.

Only the following would provide the result of 0:

if (false && true ? 1 : 0) {
    echo 1;
} else {
    echo 0;
}
