Re: [RFC] Warn about invalid strings in arithmetic

Hi François, François Laupretre wrote:

I would suggest we still accept leading and trailing blanks without E_NOTICE. That's easy to implement (leading blanks are already accepted and adding non-blank trailing char detection is trivial) and would greatly reduce BC breaks.

Leading whitespace is already accepted by zend_is_numeric_string, the problem is trailing whitespace. While that could be changed, it also affects function parameter and return type checks, so I don't know if it's within the scope of this RFC. Thanks. -- Andrea Faulds https://ajf.me/
