Description:
------------
FILTER_VALIDATE_BOOLEAN never returns null like its mentioned in the
Manual ("otherwise null") without the FILTER_NULL_ON_FAILURE-Option.
Even in the Manual is mentioned, that only String-"Booleans" will
filterd, but true also returns true.
Maybe without the Option the Manual is a kind of out-of-date, but the
fact, that "false" is a Failure, but "true" isnt, seems strange to me.
Reproduce code:
---------------
var_dump( filter_var('false', FILTER_VALIDATE_BOOLEAN));
var_dump( filter_var(false, FILTER_VALIDATE_BOOLEAN));
var_dump( filter_var('true', FILTER_VALIDATE_BOOLEAN));
var_dump( filter_var(true, FILTER_VALIDATE_BOOLEAN));
var_dump( filter_var('false', FILTER_VALIDATE_BOOLEAN,
FILTER_NULL_ON_FAILURE)); // bool(false)
var_dump( filter_var(false, FILTER_VALIDATE_BOOLEAN,
FILTER_NULL_ON_FAILURE)); // NULL
var_dump( filter_var('true', FILTER_VALIDATE_BOOLEAN,
FILTER_NULL_ON_FAILURE)); // bool(false)
var_dump( filter_var(true, FILTER_VALIDATE_BOOLEAN,
FILTER_NULL_ON_FAILURE)); // bool(false)
Expected result:
----------------
// first 4 lines:
bool (false)
NULL
bool (true)
NULL
// last 4 lines the same
Actual result:
--------------
bool (false)
bool (false)
bool (true)
bool (true)
bool (false)
NULL
bool (true)
bool (true)
