Now that the new PHP Foundation has been announced, I've been asked if we'd mind configuring a Sponsor button on our github.com project profile. https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/displaying-a-sponsor-button-in-your-repository
Pro: Gives appreciative users somewhere to send their appreciation and the project doesn't have to worry about all the tax implications. Con: PHP has always remained unbiased regarding frameworks and libraries, and I think the same should apply to other external organizations, like the foundation. There are, in fact, other foundations already in existence, and if we send traffic to one, we should send traffic to all. An alternative may be to link to the various foundations from php.net (and github.com/php) with some text stating that they are all independent organizations which contributors should assess individually. Looking forward to thoughts, -Sara
