This would be a valid point 20 years ago.

PHP functions can be namespaced. I can just write myLib\array_find, otherLib\array_find. You choose what implementation you want when importing. IDE will pick the correct one.

So, zero chances of collision.

Read my comment and all previous comments again.

Don't write such meaningless words and waste your and other people's time when you don't even understand what people are talking about.

Your previous comment makes little sense and your reply is just angry and explains nothing.

A tool to avoid collision was introduced decades ago. This tool was made proeminent by the language and the ecosystem (PHP-FIG, frameworks, books, popular PHP celebrities).

You literally have to had stopped programming PHP more than a decade ago to not understand namespaced functions.

This problem of collision was seen miles ahead, and people were gently introduced to the idea that the global namespace belongs to PHP builtins and you should not pollute it even further.

I would say it is consensus for the PHP community that if your code broke because you defined array_filter globally before 8.4, then your code sucks and you don't know PHP.
