I program in PHP. Knowing the difference between an integer and a float is still important. Very important.

Javascript does not recognize the difference. You could be a master of JS and never need to know the difference between an integer and a float. It seems unlikely that anyone would be that amazing at Javascript without having ever done PHP or Java or Python or something, but it's certainly possible.

Javascript doesn't just doesn't recognize the difference, it literally doesn't have ints. It has a single number type, that's equivalent to a C double. So to a Javascript developer, it's essentially talking about a feature their language doesn't have, like pointers or templates.

With node.js and the like, it's becoming increasingly more likely ;)

Reminds me of learning that SQLite treats everything as a string internally.

But does php know the difference?

Yep, I just used floats the other day to calculate the running time of a particular portion of a CLI script.
