php - Rand(Min, Mx) undefined variable

Question

您好，我有以下代码:

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 resultid desc LIMIT 1");
    $this->MaxResult = $row['resultid'];
    

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

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

但是我收到了这个错误:

PHP Notice: Undefined variable: MinResult in /var/www/html/betserver.php on line 539

PHP Notice: Undefined variable: MaxResult in /var/www/html/betserver.php on line 539

请帮忙

修复第 539 行以引用您刚刚创建的类变量:

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

(注意每个之前添加的$this->)
