In a Universe where consistency, soundness, orthogonal API design, modularity and evidence that the developers gave some thought to their language is expected. I would like to believe that this is such a Universe.

I mean, many of the endless list of functions imported into the default namespace were named so that their hashing distribution worked well with strlen for a hash. How much work went into working around the fact that just about the worst hashing function that you can come up with in three seconds was used?

And we can enumerate such blunders all day here. There are many better languages with good tooling, and guess what, they're free. I wouldn't use PHP if I can avoid it, and there's ample chance to avoid it nowadays.
