thinkphp怎么遍历query查询结果

[allen12345]

我在控制器中遍历查询结果，然后做些处理。
$sql="select CC from XXX";
$db = M();
$rs= $db->query($sql); ////////遍历RS
foreach ($rs as $key => $value)
{
//获取每条记录的"CC"字段的值
$CC= $value; //不成功！
$CC= $value[1]; //不成功！
$CC= $value[0]; //不成功！
$CC= ？？ //////////////help!!!!!
}

foreach ($rs as $value)
{
//获取每条记录的"CC"字段的值
$CC= $value; //不成功！
$CC= $value[1]; //不成功！
$CC= $value[0]; //不成功！
$CC= ？？ //////////////help!!!!!
}

$rs= $db->query($sql); ////////遍历RS print_r($rs); 贴出结果

我的语句就是查询某个表的所有列的名称，然后把名称取出来再加工

[allen12345]

array(33) ( [0] => array(1) ( [column_name] => (string) ID ) [1] => array(1) ( [column_name] => (string) UserName ) [2] => array(1) ( [column_name] => (string) PSW ) [3] => array(1) ( [column_name] => (string) NickName )

print不知道在哪看结果，鼠标移动过去显示这些东西的值

[xuzuning]

foreach ($rs as $value) { echo $value['column_name']; }
