Description:
------------
If PHP has been compiled with the --disable-ipv6 option, the constant STREAM_PF_INET6 should not exist. It could be useful to detect whether IPv6 has been enabled. To ensure BC, it would be better to set STREAM_PF_INET6 to -1 (or 0, false…).

We could already detect if IPv6 has been disabled with the AF_INET6 constant, declared in ext/sockets/sockets.c with #if HAVE_IPV6, but this solution is worthless if PHP has been compiled with the --disable-socket option. We could use IPv6 with stream_* functions, not only with socket_* functions.

Test script:
---------------
$ php -r "var_dump(defined('STREAM_PF_INET6'), STREAM_PF_INET6);"
$ php -i | grep "IPv6"

Expected result:
----------------
bool(true)
int(-1)
IPv6 Support => disabled

Actual result:
--------------
bool(true)
int(30)
IPv6 Support => disabled

Thank you for the report, and for helping us make PHP better.

I think we should not define STREAM_PF_INET6 in case we have IPv6 disabled. Patch committed (sorry, I forgot to include your credits :/)

Credits?

Glad to see the proposition approved and the patch applied.
