So, this is wierd:

$b = true;
var_dump($b);//boolean true

if(!$b)echo '!$b I wont echo, correctly so ';
if($b)echo '$b I will echo, correctly so ';

if($b == 'false')echo '$b == I will echo, which is wrong ';
if($b === 'false')echo '$b === I wont echo, which is correct ';

if($b == 'true')echo '$b == I will echo, which is kinda correct ';
if($b === 'true')echo '$b === I wont echo, which is very correct ';

Yes, I know that 'true' and 'false' are strings, not bool.

this one:
if($b == 'false')echo '$b == I will echo, which is wrong ';

I dont see why boolean true is equal to string false in any way.
