Um, I'm working on a PHP codebase at the moment. I hate the PHP standard library. It's awful and awkward, but my job is to make shit work, so I do, even if I hate every minute of it.
Thank god, we convinced our bosses to rewrite our legacy systems in elixir, since ~10years of iterative php progress grinded to a halt with lasagna layers of spaghetti code of homegrown-everything. Unmaintainable now, but the feature request keep coming in, and will do for years to come.
