Description:
------------
When connecting to an IPv6 address, either hostname or raw address in [] an 'unknown error' is thrown. This problem occurs on both Linux and BSD and both test machines can correctly telnet to the requested address.

phil@127dot0dot0dot1:~$ php info.php | grep -i ipv6
IPv6 Support => enabled
phil@127dot0dot0dot1:~$

Reproduce code:
---------------
<?php
$a = fsockopen('[2610:1e8:2900:a::8]', 6667);

if ($a) { echo 'yay'; } else { echo 'nay'; }
?>


Expected result:
----------------
The code should echo 'yay'.

Actual result:
--------------
Warning: fsockopen(): unable to connect to [2610:1e8:2900:a::8]:6667 (Unknown error) in /root/test.php on line 2

Was PHP compiled properly? ie. did you enable ipv6 support? (check phpinfo() output for 'IPv6 Support'.
 [2009-11-18 14:37 UTC] phil at lavin dot me dot uk 
The grep output in the original bug report is of a phpinfo. It is 'enabled'

# sapi/cli/php -r 'var_dump(fsockopen("[2610:1e8:2900:a::8]", 6667));'

Warning: fsockopen(): unable to connect to [2610:1e8:2900:a::8]:6667 (Network is unreachable) 

..so I'd say your system is either misconfigured or missing ipv6 support or the target is not there. :)
 [2009-11-18 16:55 UTC] phil at lavin dot me dot uk 
My system is fine. It has IPv6 support and the target is there.

phil@127dot0dot0dot1:~$ telnet 2610:1e8:2900:a::8 6667

I have had this same issue on both a Linux box and a BSD box running 5.2.11

I have just tested it on 5 different servers running 5.2.11. All give the same error, e.g.

phil@server:~$ php -r 'var_dump(fsockopen("[2610:1e8:2900:a::8]", 6667));'

You have new mail in /var/mail/phil
phil@server:~$

This is regardless of whether they do or don't have IPv6 support.

A server running 5.2.9 gives what you got:

phil@server1:~$ php -r 'var_dump(fsockopen("[2610:1e8:2900:a::8]", 6667));'

When compiled properly 5.2.11 will give what I got.
 [2009-11-18 17:05 UTC] phil at lavin dot me dot uk 
Can you please define 'properly' so that I may contact the package maintainers of PHP for Debian, FreeBSD and RHEL to notify them that they are doing something wrong.

I would have thought that, considering phpinfo reports that IPv6 is enabled in the php compile on every server, it should work correctly.
 [2009-11-18 18:03 UTC] jani@php.net 
It's properly configured if it's not disabled in configure line with --disable-ipv6 option. f.e.:

# rm -f config.cache && ./configure && make
# sapi/cli/php -r 'var_dump(fsockopen("[2610:1e8:2900:a::8]", 6667));'

Having just downloaded and compiled 5.2.11 (just using ./configure with no options)...

phil@127dot0dot0dot1:~/php5/php-5.2.11$ sapi/cli/php -r 'var_dump(fsockopen("[2610:1e8:2900:a::8]", 6667));'

The same problem exists with 5.2.11 on Windows too.

Of course that's a known problem, and exists also in PHP 5.3.0. In PHP 5.3.1 (rc/dev) that's fixed.

Is (/was) there no backport to 5.2.11?

I assume this fix will be pushed out in 5.2.12?

This bug has been fixed in SVN.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at

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

The fix is already in and will be part of 5.2.12
