Answer 1

I look at it the following way:

1. PHP is designed as a web programming language and all the input of the pages is based on strings [human-like perception] [This is by the way is also true for JavaScript]
2. Hence, all the strings which look like numbers (is_numeric() function), preliminary behave like numbers [comparison, casting].
3. That explains why extreme cases, like "0" are first implicitly thought to be cast to (int)0 and only then to false.
