Are there any plans to allow bitwise declaration of flags?
Example:
class foo {
const FLAG_1 = 1;
const FLAG_2 = 2;
const FLAG_3 = 4;
private $Flags = self::FLAG_1 | self::FLAG_3
}
Hi,
This is not allowed since declaration values should be resolvable at compile
time. I.e. they can not be an expression, but only a value literal.
While technically expression folding is possible, it's not implemented in
any part of the PHP engine (AFAIK), and I don't think it's planned any time
soon.
To do what you want, initialize the value in the constructor:
class foo {
...
private $flags;
function __construct()
{
$this->flags = self::FLAG_1 | self::FLAG_3;
}
}
