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注意：未定义的变量：第539行/var/www/html/betserver.php中的MinResult

PHP注意：未定义的变量：第539行/var/www/html/betserver.php中的MaxResult

请帮忙

修复第539行以引用刚刚创建的类变量：

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

（注意每个之前添加$this->）

Rand（Min，Mx）未定义变量
