I just updated the patch and RFC to include overflow safety for the integer
type hint. This means that the following code is an error:
function foo(int $a) {}
foo(‘8493284029384029384028409304249230894’);
This is actually a level of safety you couldn’t get with any other proposal. If
you explicitly cast with (int) it will silently saturate/cap the integer (data
is lost), and zend_parse_parameters will silently saturate or truncate
(depending on the function).
This is consistent with passing a float. Were I to do the following, it was
already an error in the proposal:
function foo(int $a) {}
foo(8493284029384029384028409304249230894.0);
