RE: [PHP-DEV] What do we need strict scalar type hints for?

Checking IS_<type> at the C level after implicit conversions and checking this at the PHP level are very different. IMHO, the key point is the concept of 'type'. Strict typing considers a one-to-one correspondence between PHP types and zval types, which is nonsense. At the PHP level, any value returning true through is_numeric() IS a 'number', and it must remain so. Any such value with a null decimal part is an 'integer' (not the result of 'is_int()') and so on. As long as we don't agree on 'smart' high-level types and the corresponding matching rules against zval type and value, we won't agree on anything. This is what I am currently defining in the upcoming DbC RFC. Hopefully, a first version will be released tomorrow, depending on Yasuo's and Dmitry's opinion. Cheers François
