${var} string interpolation deprecated in php8.2

[alexandreelise]

What is this feature about (expected vs actual behaviour)?

its in the title

How can I reproduce it?

install voku/portable-utf8 version ^5.4 on php 8.2.x

Does it take minutes, hours or days to fix?

minutes it's in UTF8.php file

Any additional information?

I don't want to be a hassle, just trying to be helpful and report what might be useful to you.

Here are the logs with php 8.2.x:

might help about what seem be to an issue.

This error came to my log file when using Joomla 4.2.6 which has voku/portable-utf8:^5.4 as composer dependency.
Placed in libraries/vendor/voku/portable-utf8 in this repo
https://github.com/joomla/joomla-cms.git

It would require to backport #181 to version 5.

I have a branch with this fixed, but I can't merge it back to the 5.4.51 tag.
@voku I'm not sure how you want to handle this, or if you just don't want to. :)

Unfortunately, this is a dependency of a dependency, so I am pretty powerless to just upgrade to the latest version.

@mrunkel maybe you can push it as draft and I will merge the changes by hand, what do you think?

Just for people stumbling upon this issue from Google or something...
This error also seems to appear in the latest version of Nextcloud (26.0.1) with the "recognize" plugin:

Using ${var} in strings is deprecated, use {$var} instead at /var/www/xxxxx/apps/recognize/vendor/voku/portable-utf8/src/voku/helper/UTF8.php#13409

Curious if there's been any traction on this.

For your information, your library is spamming deprecation log in my project because it is used by wamania/php-stemmer and we are using php 8.2.
