The takeaway from these titles is not the problems themselves but the pattern of failure and the issue of trusting the tool itself. Other than that if you've used php enough yourself you will absolutely find frustration in the standard library

If you're looking for something more exhaustive there's the certified hood classic "PHP: A fractal of bad design" article as well that goes through ~~300+~~ 269 problems the language had and/or still has.
