Question

我有一个成员表，其中的字段为member_id, referrer_member_id, sales_hold_fund。我想检查会员的销售持有资金是否> 100，如果它大于100，我想从销售持有基金减去100。所以这应该是一个循环，直到销售持有基金大于100。

示例：

销售持有基金是300，首先应该检查它是否大于 100如果是，它将从300减去100,200将是余额，如果是的话，它会检查余额是否大于100 再次它将从200减去100.现在它将检查余额金额大于100而不是不大于它应该停止循环。

我试图实现这个，但这是一个无限循环。

  $stmt = $dbConnection->prepare("select Member.sales_hold_fund,Member.referrer_member_id from Member where member_id=?");
    $stmt->execute(array($member_id));
    $memberC = $stmt->fetch(PDO::FETCH_ASSOC);

    $fund = $memberC['sales_hold_fund'];

    while($fund > 100)
    {
        $balance_amount = $sales_hold_fund - 100;
        echo $balance_amount;
        $this->updateSalesHoldFund($member_id,$balance_amount);

        $profit_sharing = 0.20 * $amount;

        $referrer_fees = 0.10 * $amount;

        if(!empty($referrer_member_id))
        {
          //  $this->createHundredId($date_of_purchase,$referrer_member_id,$profit_sharing,$referrer_fees,$member_id,$referrer_member_id1);

        }
        else if (!empty($referrer_member_id1))
        {
        //    $this->createHundredId($date_of_purchase,$referrer_member_id,$profit_sharing,$referrer_fees,$member_id,$referrer_member_id1);
        }

        else{
          //  $this->createHundredId($date_of_purchase,$referrer_member_id,$profit_sharing,$referrer_fees,$member_id,$referrer_member_id1);
        }

    }

我想在更新时返回余额，并检查它是否大于100.现在它将无限循环，因为我只检查$ fund＆gt; 100永远不会更新。

我该怎么做？请帮忙......谢谢..

有人可以帮忙吗？谢谢。

更新了答案

您正在尝试更新$sales_hold_fund，根据您的说明，您的代码应如下所示。将$fund替换为$sales_hold_fund并对其执行操作。它也将替换您的$balance_amount。

$stmt = $dbConnection->prepare("select Member.sales_hold_fund,Member.referrer_member_id from Member where member_id=?");
$stmt->execute(array($member_id));
$memberC = $stmt->fetch(PDO::FETCH_ASSOC);

$sales_hold_fund = $memberC['sales_hold_fund'];

while($sales_hold_fund > 100)
{
    $sales_hold_fund = $sales_hold_fund - 100;
    echo $sales_hold_fund;
    $this->updateSalesHoldFund($member_id,$sales_hold_fund);

    $profit_sharing = 0.20 * $amount;

    $referrer_fees = 0.10 * $amount;

    if(!empty($referrer_member_id))
    {
      //  $this->createHundredId($date_of_purchase,$referrer_member_id,$profit_sharing,$referrer_fees,$member_id,$referrer_member_id1);

    }
    else if (!empty($referrer_member_id1))
    {
    //    $this->createHundredId($date_of_purchase,$referrer_member_id,$profit_sharing,$referrer_fees,$member_id,$referrer_member_id1);
    }

    else{
      //  $this->createHundredId($date_of_purchase,$referrer_member_id,$profit_sharing,$referrer_fees,$member_id,$referrer_member_id1);
    }

}

您必须在while循环和睡眠连接中使用db函数。

    while($fund > 100)
    {

$stmt = $dbConnection->prepare("select Member.sales_hold_fund,Member.referrer_member_id from Member where member_id=?");
    $stmt->execute(array($member_id));
    $memberC = $stmt->fetch(PDO::FETCH_ASSOC);

    $fund = $memberC['sales_hold_fund'];

    ob_start();
    sleep(1);
................
............
}

循环进入无限循环
