As Stuart pointed out, type-hinting currently only works for classes and
arrays. Scalar type-hinting is planned for the future, but for now you're
left with enforcing it in the function itself. You can create a class with
static helpers to make this easier if you're going to do it frequently.
As for documentation, go with the PHPDoc standard:
/**
* Converts a spelled-out number to the equivalent integer.
*
* @param string $s must be a spelled out number, e.g. "five" rather than
"5".
* @return int
*/
function int_func($s) { ... }
To confuse me a bit further, I can't find a definitive list of the
> basic type names. For example, is it "integer" or "int"?
I use "int" and "bool" with the rest spelled out which works with casting.
Peace,
