Cannot bind IPv6 [::] (any) about socket HOT 6 CLOSED

Thanks for reporting!

The example code essentially executes this under the hood:

$a = stream_socket_server('tcp://0.0.0.0:9988');
$b = stream_socket_server('tcp://[::]:9988');

Which emits the very same error.

If you omit the first server, then the second works just fine. It looks like this is intended behavior.

I hope this helps 👍

If that's intended how to open a socket for both v6/v4?

Maybe this is related?

I'm on linux and indeed this happens to be true. Using just the IPv6 [::] address listens on both the stacks, because my ubuntu server has 0 in /proc/sys/net/ipv6/bindv6only

Thanks for confirming this! 👍

I've just filed feature request #59 so you may eventually specify the ipv6_v6only context option 👍

For the reference, #64 introduced the required socket context options, so you may want to check out the v0.4.6 release 👍
