[RFC] [Discussion] FILTER_THROW_ON_FAILURE View as Markdown

Hi internals,

I'd like to start the discussion for a new RFC about adding
a FILTER_THROW_ON_FAILURE flag to the filter extension.

• RFC: https://wiki.php.net/rfc/filter_throw_on_failure
• Implementation: https://github.com/php/php-src/pull/18896

I think this is an excellent idea.

I left a review on the PR, with a suggestion to improve the exception
message (slightly):
https://github.com/php/php-src/pull/18896/files#r2204824115

cheers,
Derick

Given the lack of further feedback outside of discussing the exception
message, either here or on GitHub, I plan to open the vote in the next few
days.
