Description:
------------
When using scalar type hinting, some malformed integers report a TypeError, while others raise a E_NOTICE.

Test script:
---------------
function test(int $a) {}

test(null); // TypeError
test("x"); // TypeError
test("x1"); // TypeError
test("1x"); // E_NOTICE

Expected result:
----------------
test("1x"); // TypeError

Actual result:
--------------
test("1x"); // E_NOTICE

See https://wiki.php.net/rfc/scalar_type_hints#behaviour_of_weak_type_checks

I don't see any mention of the potential for notices on the function arguments page...

The behavior is now precisely documented[1].  The type
declarations section[2] could link to that, and should likely have
a general subsection about "coercive typing".
