Hello all,
I'd like to propose a new RFC for 5.NEXT:
https://wiki.php.net/rfc/const_scalar_expressions
This allows for defining constant expressions which are resolved at compile
time.
What should that be for?
const FOO = 1 + 1;
const BAZ = HELLO . WORLD!;
Why not just writing

Would this allow using constants, too? Class constants?
const FOO = 1;
const BAR = self::FOO + 1;
const BAZ = self::FOO + 2;
const BARF = GLOBAL_BARF;
const IMPORT = otherclass::IMPORT; // with autoloading?
In my opinion these would start to make the feature useful.
Even more useful, but

Hi!
https://wiki.php.net/rfc/const_scalar_expressions
I like the idea, but absence of constant support makes this thing much
less useful, as you can't do things like:
public $angle = M_PI/2;
I think this is one of the reasons this idea was never implemented -
because without constant support

Those are not constants, but expressions which can't be run during
compile time.
Hi,
Just asking: Does this cover only declarations, or every constant
expression, for example
$weeks = $secs / (60 * 60 * 24 * 7);
becomes to the opcode-equivalent of
$weeks = $secs / (604800);
?

Hi!
Perhaps something for OpCache's optimizer though, if it doesn't already
do that...
The problem with that is once you start to do conversions, things quicky
go south, as conversions can depend on runtime variables, and people get
really weird bugs when their expressions are not evaluated
