From PHP 8.0, calling min() with an empty array as argument will throw a ValueError.
Current doc does not mention this.

Fatal error: Uncaught ValueError: min(): Argument #1 ($value) must contain at least one element in [...]

Indeed. max() has the same problem; and we should probably clarify, that "calling min() with an empty array as argument" refers to the second signature (see https://3v4l.org/Ic2BQ).
