[Vote] Add form feed as a whitespace character in trim, ltrim and rtrim

Oops my bad, I didn't realize the new version is released. I am convinced by Ben that the feature should be in 9.0 since this is technically a BC break.

Hmmm, so in this case I am not that sure whether I should directly reopen the vote or put in 'under discussion' again and been through another cool down period.

Cheers,

Hi internals,

I am posting this to announce the start of the voting process of the RFC 'Add form feed as a whitespace character in trim, ltrim and rtrim'

Wiki page: https://wiki.php.net/rfc/trim_form_feed
discussion thread: https://news-web.php.net/php.internals/129706
date to end: 2026/2/6 15:30:00 UTC

Thank you in advance for your participation.

It shows "PHP 8.5" as target version in the RFC. That's not possible, as it had already been released.

cheers

Just got the newest email. I will reset the vote again and change the version to 9.0. Thank you.

Cheers,

I've voted "no" on this RFC since the RFC says the proposed PHP version
is PHP 8.5, which I interpret as meaning PHP 8.6, since 8.5 was released
in November.

Even if PHP 8.6 is the proposed version, I still think the target
version should be PHP 9.0, since this is a BC break. I mentioned my
concern about this being a BC break in the discussion thread.

The RFC is also clear this is a BC break. It says:

This is a backward incompatible change. Scripts that rely on
trim() preserving leading or trailing Form Feed characters will
be affected.

I'm a little surprised by the number of folks who voted "yes" on this,
despite it being very clear this is a BC break and PHP "Next" is the
implied proposed version.

Cheers,
Ben

It looks like you changed the proposed PHP version from 8.6 to 8.5 on
the same day you opened voting.[^1] IMO, this was at least a minor
change (according to our Feature Proposals policy), which requires
notifying the mailing list of the change and should have triggered a
7-day cool down before voting could begin.[^2]

I appreciate the work you've put into this, and I agree with the need
for this change, but I'm a little worried those who voted "yes" might
not have noticed the proposed version change on the RFC from PHP 8.6 to
PHP 8.5.

Cheers,
Ben
