PHP Bug Type: Feature/Change Request
Bug description: string -> boolean conversion of "\0" could give FALSE
Description:
------------
It might be useful that (boolean)"\0" would give FALSE.
E.g. MySQL's BIT(1) column type can be used to store boolean values, but
now PHP converts whatever value to TRUE.
Reproduce code:
---------------
header('Content-Type: text/plain');
echo "\nfalse: ".ord(false);
echo "\ntrue: ".ord(true);
echo "\n\\0: ".(boolean)("\0");
echo "\n\\1: ".(boolean)("\1");
// ord() is here just for thoughts context...
Expected result:
----------------
false: 0
true: 49
\0: 0
\1: 1
Actual result:
--------------
false: 0
true: 49
\0: 1 <----- HERE
\1: 1
