问如何在不影响其他函数的情况下结束/终止检查表中的IP地址的函数

EN

function CheckIfUserIpExist() {
    $connection = DBconnect();
    $user_ip = $_SERVER["REMOTE_ADDR"];
    $sql = "SELECT * FROM views WHERE user_ip = ?";
    $stmt = $connection->prepare($sql);
    $stmt->bind_param("s", $user_ip);
    $stmt->execute();
    $stmt->store_result();
    $users_ip = $stmt->num_rows;
    if($users_ip > 0) {
        die();
    }
}

function AddUserWhenPageIsViewed() {
    $connection = DBconnect();
    $user_ip = $_SERVER["REMOTE_ADDR"];
    $time_ = date('Y-m-d G:i:s');
    $sql = "INSERT INTO views (user_ip, time_) VALUES (?,?)";
    $stmt = $connection->prepare($sql);
    $stmt->bind_param("ss", $user_ip, $time_);
    $stmt->execute();
}

CheckIfUserIpExist(); 
AddUserWhenPageIsViewed();
