    I say that php breaks math entirely, and is therefore bad. “” == null returns true null == [] returns true “” == [] returns false.

    In more recent versions it gets worse, because it has 0 == “any text” return true, “any text” == true return true, and 1 == true return true So indirectly 1 = 0, and now math is more directly broken.

      If you’re trying to directly compare different variable types in any language without strong typing, you’re going to have edge-case results which you might not expect.

      My “coding like a moron” message still stands. PHP isn’t a strongly typed language and it doesn’t tell you off for trying stupid stuff like comparing a string with an int. Nor do other languages like JavaScript.

        Also using duck typing fails against php is pretty funny when it’s being compared against JAVASCRIPT of all things.

      I just tested these out out of curiosity.
      0==“text” returns false in PHP 8.2 as I’d expect.

      The others make sense in the way that php juggles between types. An empty variable can type-juggle to null, but an array can’t be directly compared with a string.

      (Although you wouldn’t really want to compare an array with a string, PHP just treats an array as greater than other variables. So weirdly, ([] > “”) == true.)
