Question

我有表用户的mysql数据库。在用户中有列：
id , username , password , ip

我有管理面板，我需要显示具有相同IP的用户，例如

User1→User2

Nick1→Nick2

等

我怎么能用php.Thanks做这件事，这很紧急。谢谢。

Answer 1

这是你的SQL查询。

SELECT username, list.ip FROM users
INNER JOIN (SELECT ip FROM users
GROUP BY ip HAVING count(id) > 1) dup ON list.ip = dup.ip

用于PHP：

$sql = "SELECT username, list.ip FROM users
INNER JOIN (SELECT ip FROM users
GROUP BY ip HAVING count(id) > 1) dup ON list.ip = dup.ip";

$result = mysql_query($sql,$con);

while($row = mysql_fetch_array($result))
{
    echo $row['username'];
}

<强>更新

请尝试此查询：

$sql = "SELECT username FROM users WHERE ip in 
(SELECT username FROM users GROUP BY ip HAVING count(ip) > 1)";

Answer 2

select users 
from users_table 
where ip ='thisIp'

Answer 3

获取这样的重复IP列表， SELECT COUNT(*) as acount, ip FROM users GROUP BY ip HAVING acount > 1 然后使用这些结果，获得与这些IP匹配的所有帐户

PHP - MySQL，排序克隆
