PHP: Cracks in the foundation 15 years ago
I havent developed in php in years, but here is my tale on it from my current point of view.
Of this whole article the one thing that jumped out at me was "broken and ignored tests". Being an open source developer myself, I greatly value the tests in every open source project. Nevermind the fact that this is PHP which warrants the use of tests even further because of the various points the author makes.
I hope that going forward the maintainers of the PHP core ensure that every bug fix has a passing unit test along with it. That would at least keep the dam holding back the flood intact.
