Subject: [RFC] Adding a "Stringable" interface to PHP 8
From: nicolas.grekas+php@gmail.com (Nicolas Grekas)
--0000000000001d923c059cbc6f83
Content-Type: text/plain; charset="UTF-8"
Hello everyone,
as announced last week, I'm officially opening a discussion for adding a
"Stringable" interface to PHP 8.
The RFC and its rationale are presented here as required:
https://wiki.php.net/rfc/stringable
The patch is found on GitHub, where some discussions happened already, you
might be interested in having a look:
https://github.com/php/php-src/pull/5083
TL;DR, I think we need an interface to allow passing objects with a
__toString() method in a type-safe way, using the string|Stringable type.
Here is the stub of the proposal:
interface Stringable { public function __toString(): string; }
I invite everyone to review the RFC before commenting here as I tried to
sum up considerations that some already had before and that you might have
too.
Cheers,
Nicolas
