I've taken a few hours this morning to port my 5.2 type hinting
patch to
5.3. In recognition of a need for a more 'flexible' numeric type I've
introduced (numeric) type hint that would allow bool/int/float data
types as
well as a string containing a numeric entity as identified by
is_numeric_string(). For completion i've also added (scalar) data
type that
will allow any scalar data element.
I think this will go a long way to addressing people's concerns when
this came up previously.
The patch is available here: http://ia.gd/patch/type_hint_53.txt
I presume the idea is that some people (if they so chose) would want
to type hint every parameter in their program. To facilitate this, I
might suggest a "mixed" hint (like in the docs), and a null hint
(though I'm not sure if it would be called "null" or "unset" or both).
Finally, I don't want to ruin this, but last time there was
disagreement over whether numbers should be coerced to the specified
types, or left alone. What does your patch do?
ie function x (int $x) { echo is_int ($x); } x ("5");
Thanks,
Paul
It should be noted that this is not the first idea for type hints,
that
credit goes to Hannes Magnusson who had posted a similar patch on the
internals list back in 2006. Also, back in 2008 Felipe Pena wrote a
type
hinting patch for PHP that is available on wiki.php.net.
