Hello, IMHO it’s only a declaration issue. In other terms, if documentation of strlen says:
strlen ( string $string ) : int then I mean that $string MUST be a string, and return value MUST be an int. But then we found that if $string is null, zero is returned. If $string is an array, null is returned … We simply need consistency between how a function is documented, and how it really works. I mean, it may also be convenient for strlen to accept a parameter type other than string (such as null), but it must be well documented.
