PHP Bug Type: Documentation problem
Bug description: ?: (ternary) - shold operate as in C, but does not
Description:
------------
The documentation says in the section Comparison Operators:
"Another conditional operator is the "?:" (or ternary) operator, which
operates as in C and many other languages"
This is not true, because in C and other languages the ternary-operator is
parsed/compiled from left to right, and therefore cases other results.
The included code returns "1" in C and JavaScript, for example, but "2" in
PHP
Reproduce code:
---------------
$c1=true;
$c2=false;
echo $c1 ? 1 : $c2 ? 2 : 3;
Expected result:
----------------
1
Actual result:
--------------
2
