Description:
------------
When getaddrinfo fails fsockopen() fails to return an error string or error code.

Reproduce code:
---------------
<?php

$code = 0;
$message = '';
$fp = fsockopen('www.asdf98070978.org', 80, $code, $message);
if (!is_resource($fp)) {
    echo 'ERROR: ' . $message . '(#' . $code . ')' . "\n";
} else {
    echo 'Connected!' . "\n";
    fclose($fp);
}

?>


Expected result:
----------------
fsockopen() should return false and set an appropriate error code and error message.

Actual result:
--------------
It spits out a warning and doesn't include any sort of error message or string:

Warning: fsockopen(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in /home/jstump/repository/wildcat/branches/config/foo.php on line 5

Warning: fsockopen(): unable to connect to www.asdf98070978.org:80 (Unknown error) in /home/jstump/repository/wildcat/branches/config/foo.php on line 5
ERROR: (#0)

Hello,

I have not been able to reproduce it. Can please give us an extra explanation about it?
 [2008-02-07 00:48 UTC] joe at digg dot com 
Did you run the reproduce code? I can consistently reproduce no error and warnings being thrown from many machines. What was the output when you ran the code below? Though, depending on the machine, I sometimes get an error code.

Hello,

Got the same with 5.2.5 and 6 (32 bits machine)

[root@porcupine bugs]# /usr/local/php6/bin/php fsockopen.php

Warning: fsockopen(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /root/bugs/fsockopen.php on line 6

Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows (zip):
 
  http://snaps.php.net/win32/php5.2-win32-latest.zip

For Windows (installer):

  http://snaps.php.net/win32/php5.2-win32-installer-latest.msi

Seems to be fixed since I get this:

ERROR: php_network_getaddresses: getaddrinfo failed: Name or service not known(#0)

Note: The code is 0 always when failure happens before connect() (also mentioned in the friendly manual :)
