@dseguy
Think is A::{A}; cause others seems ok, and I dont understand this.

dseguy, 7 months ago

@MaxKoder This is new in PHP 8.3 : dynamic class constant.
The weird part here is that the constant name is evaluated: so we can use a global constant name there.
In the end, this is not a call to A::A, but a call to A::value_of_constant('A').
It's easier to recognize with A::{$A} where $A is a constant.

Thanks for your reply, it will become hard to understand ^^

@dseguy an extra }

dseguy, 7 months ago

@Daddaniele I fixed that one in the picture.
Now, where is the problem?

velkuns, 7 months ago

@dseguy the last one has one extra }
But probably is a typo.

Otherwise, I don't know why it should be broken.

dseguy, 7 months ago

@velkuns Yep, I fixed it.
So, where is the error?

velkuns, 7 months ago

@dseguy is it $A{A} part that causes the error ? It is the only thing that differs from others cases.

dseguy, 7 months ago

@velkuns Yes, that's it. curly braces are not allowed anymore to access elements at position x in a string or array, since PHP 8.0.

The rest are variations between dynamic class constants and dynamic property, with global constants for a bit of weirdness.

velkuns, 7 months ago

@dseguy ah, yes, of course. But I didn't know this syntax works with letters between { }

dseguy, 7 months ago

@velkuns another good reason to avoid this syntax.

@dseguy the last line ?>

dseguy, 7 months ago

@admin Not bad. Any reason?

admin, 7 months ago

@dseguy
if have no clue
?>

dseguy, 7 months ago

@admin It is valid to leave the (last) closing tag out. Not the problem here.

admin, 7 months ago

@dseguy is it the opening tag <?
(still have no clue)

dseguy, 7 months ago

@admin
I'm giving you more time to find it.
The road is the destination!

admin, 7 months ago

@dseguy
now i will find it

admin, 7 months ago

@dseguy
Is this a good start?:

class A {
const string A = 'A';
}

dseguy, 7 months ago

@admin It is.
