Question

$a = true;
$b = true;


if (($a == false) || ($b == false)) {
 echo "BAD";
} else {
  echo "OK";
}

why this show me “BAD”? how can i fix it?

Answer 1

The code will not echo BAD because the expression evaluates to false, yielding OK:

($a == false) || ($b == false)
↓
(true == false) || (true == false)
↓
false || false
↓
false

Some other error must exist.
