PHP Windows 7 IPv6 Work-Around ip列不能为null

标签: php ipv6

使用以下PHP / SQL ...

function ip2long6($ip)
{//ipv6 to ipv4 (string) to get Windows 7 local working
// Temp work-around until we convert the string to support ipv6 natively in SQL.
 if (substr_count($ip, '::')) {$ip = str_replace('::', str_repeat(':0000', 8 - substr_count($ip,':')).':',$ip);}

 $ip = explode(':',$ip);
 $r_ip = '';

 foreach ($ip as $v) {$r_ip .= str_pad(base_convert($v,16,2),16,0,STR_PAD_LEFT);}

 return base_convert($r_ip,2,10);
}

$ip = mysql_real_escape_string($_SERVER['REMOTE_ADDR']);
$ip = mysql_real_escape_string(ip2long6($ip));
INSERT INTO log (ip) VALUES (INET_ATON('1208321'))

我收到以下错误...

  

列'ip'不能为空

我们现在怎么能让$ ip兼容IPv4?


工作答案......

if (is_int($ip)) {$ipsql = mysql_real_escape_string("INET_ATON('$ip')");}
else {$ipsql = mysql_real_escape_string($ip);}

有了这个,我只需回复INET_ATON('$ip') $ipsql

答案 0 :(得分:0)

您正在使用INET_ATON转换stringed-int。该函数需要一个dotted.quad地址,例如

INET_ATON('127.0.0.1');

不是有效输入,因此该函数返回null:

mysql> select inet_aton('12345'), inet_aton('127.0.0.1');
+--------------------+------------------------+
| inet_aton('12345') | inet_aton('127.0.0.1') |
+--------------------+------------------------+
|               NULL |             2130706433 |
+--------------------+------------------------+
