如何将数据插入一个mysql行

Question

请尝试从表（addclique）中获取mysql行（＆＃39; clique_id＆＃39;）中的数据并插入另一个表（通知）但它无法正常工作。它显示一个空白屏幕。

$select=  "SELECT * FROM addclique WHERE adder_id = :session_id";
$param1= array ('session_id' => $_SESSION['id']);
$cliques= $db->query($select, $param1);


foreach($cliques as $key)
{
        $array[] = $key['clique_id'];

}
var_dump($array);
echo "true";
exit;

if  ($result= $db->query($sql, $param)) { 

        $notijfy = new Notification();
        $notijfy->addCircle($param['member_id'],$array[]);
        header ("Location: success_circle.php");
}

function addCircle($id_involve, $id_user){

 $sql2 = "INSERT INTO notification (id_involve, id_user, category) VALUES (:involve, :user, 'circle')";
 $param = array ('involve' => $id_involve, 'user' => $id_user);

  $result2= $this->db->query ($sql2, $param);
}
