從 MySQL Rand() 更改為 PHP random_int

Question

我們正在創建一個隨機數游戲。 我們目前在以下語句中使用 MySQL Rand() 函數：

private function doPreEventStart($user) {
$row = db_fetch_item("SELECT resultid FROM ResultPackage 
    where ResultPackage.slotid like '%{$this->curSlotId}'
    and ResultPackage.PackageID like '%{$user->packageid}%'
    ORDER BY RAND() LIMIT 1");
$this->curResultId = $row['resultid'];
}

我們需要將其更改為 PHP 函數 Random_Int。 請有人通過更改上述代碼來建議一種方法。 從SQL語句中的WHERE條件可以看出，隨機數仍然需要在一定范圍內。

我正在測試此代碼：

private function doPreEventStart($user) {
    $row = db_fetch_item("SELECT resultid as MaxResult FROM ResultPackage 
        where ResultPackage.slotid like '%{$this->curSlotId}'
        and ResultPackage.PackageID like '%{$user->packageid}%'
        ORDER BY resultid desc LIMIT 1");
    $this->MaxResult = $row['MaxResult'];


    $row = db_fetch_item("SELECT resultid as MinResult FROM ResultPackage 
        where ResultPackage.slotid like '%{$this->curSlotId}'
        and ResultPackage.PackageID like '%{$user->packageid}%'
        ORDER BY resultid asc LIMIT 1");
    $this->MinResult = $row['MinResult'];

    $this->curResultId = int rand ( int $MinResult , int $MaxResult )
    }
