Subject: [RFC] Scalar Type Hinting With Casts (re-opening)
From: ajf@ajf.me (Andrea Faulds)

Good evening,

PHP=92s type hinting system is rather incomplete as it does not support =
scalars, only arrays, callables and objects. In 2012, Anthony Ferrara =
created an RFC which proposed type hinting for scalar types (int, float, =
bool, string and resource) with casting, with behaviour nearly the same =
as that of zend_parse_parameters. Sadly, he later left PHP internals and =
withdrew his RFCs.

Since I am very much in favour of scalar type hints, I=92ve updated the =
patch to master and made some minor improvements, and I am re-opening =
the RFC with the intent to try and get it into PHP 5.7. The patch is =
mostly there. It needs some more tests and there are some edge cases I =
need to deal with, but it otherwise works, and I expect I can finish =
fixing it up very soon.

The RFC is here: https://wiki.php.net/rfc/scalar_type_hinting_with_cast

A pull request is here: https://github.com/php/php-src/pull/717

I=92m hoping I can get this into PHP 5.7. I think scalar type hinting =
would be a valuable addition to PHP=92s existing type hinting system.

Thanks!
