Subject: 5.4.3 type hint handling
From: ab@php.net ("Anatoliy Belsky")

Hi,

I'm experiencing an issue adding type hints to the function prototypes.
The following definition gives the "unknown typehint" error when invoking
a function

ZEND_BEGIN_ARG_INFO_EX(arg_info_trader_adosc, 0, 0, 4)
    ZEND_ARG_TYPE_INFO(0,  high, IS_ARRAY, 0)
    ZEND_ARG_TYPE_INFO(0,  low, IS_ARRAY, 0)
    ZEND_ARG_TYPE_INFO(0,  close, IS_ARRAY, 0)
    ZEND_ARG_TYPE_INFO(0,  volume, IS_ARRAY, 0)
    ZEND_ARG_TYPE_INFO(0,  fastPeriod, IS_LONG, 1)
    ZEND_ARG_TYPE_INFO(0,  slowPeriod, IS_LONG, 1)
ZEND_END_ARG_INFO();

The reason I trip up on this is to generate the xml doc proto for the
extension. Therefore I'm using the extended ZEND_ARG_INFO version. Without
type hints there are no param types in the xml.

Quickly looking at the sources I realize that 5.4.3 has an explicit type
hint check which was previously ignored in 5.3

http://lxr.php.net/opengrok/xref/PHP_5_4/Zend/zend_execute.c#600

The reason of writing this is not to start a new discussion about scalar
types, for God's sake not :), but just to point at the collision with the
current core and doc generator. A simple way to fix this would be to
restore the old 5.3 behaviour just passing on scalar types. Or may be
there were a simple solution for this, despite 5.4.3 is already issued?

Cheers
