它是我的mongodb表结构。

<?php
    include('databasecon.php');

    // GET API JSON DATA
    $coinData = json_decode(file_get_contents('https://min-api.cryptocompare.com/data/pricemultifull?fsyms=BTC,ETH,XRB,IOTA,XRP,XLM,TRX,LINK,USDT&tsyms=USD'), true);

    //SELECT ALL MAIL
    $result = mysqli_query($con, "SELECT DISTINCT email FROM user_data");
    $email_array = array();
    while($row = mysqli_fetch_array($result)){

    }

    // PORTFOLIO ARRAYS
    for ($i = 0; $i < sizeof($email_array); $i++) {
        $sql = mysqli_query($con, "SELECT DISTINCT * FROM crypto_data WHERE email = '$email_array[$i]'");
        while($row = mysqli_fetch_array($sql)){
            $myCoins[$row['currency']] = array('balance' => $row['amount'], 'boughtprice' => $row['price_when_bought']);
        }

        $portfolioValue = 0;
        $totalNET = 0;
        $Value24H = 0;

        // information in json path ['RAW'] so safeguard here to be sure it exists
        if (isset($coinData['RAW'])) {
            // then loop on all entries $cryptoSymbol will contain for example BTC and cryptoInfo the array USD => [...]
            foreach($coinData['RAW'] as $cryptoSymbol => $cryptoInfo) {

                if (!isset($cryptoInfo['USD']) || !isset($cryptoInfo['USD']['FROMSYMBOL'])) {
                    // log or do whatever to handle error here
                    echo "no path [USD][FROMSYMBOL] found for crypto: " . $cryptoSymbol . PHP_EOL;

它在mongodb中的用户表。我需要找到没有顺序的用户 从'2018-04-22 23:14:00'到'2018-04-22 23:50:00'

根据您的要求，您可能需要elemMatch运算符，有关详细信息，请查看official documentation

使用此方法，您可以在以下查询集合中执行以下操作：

 db.collcationName.find(
    {"Order" : 
        {$elemMatch: 
            {"start_date": {$not: { $gte: new ISODate('2018-04-22 23:14:00')} }, 
             "end_date": {$not: {$lt: new ISODate('2018-04-22 23:50:00')} } 
            } 
        } 
    })

您需要过滤并计算“无用”订单（“ 2018-04-22 23:14:00”到“ 2018-04-22 23:50:00”之间的订单），然后过滤没有“无用”订单的用户“订单。

您可以像这样使用聚合

db.User.aggregate(
{
    $project: {
        'name': 1,
        Orders: {
            $filter: {
                input: '$Orders',
                as: 'order',
                cond: {
                    $or: [{
                            $and: [{
                                    $gte: ['$$order.end_date', ISODate('2019-04-22 23:14:00')]
                                },
                                {
                                    $lt: ['$$order.start_date', ISODate('2019-04-22 23:14:00')]
                                }
                            ]
                        },
                        {
                            $and: [{
                                    $gte: ['$$order.end_date', ISODate('2019-04-22 23:50:00')]
                                },
                                {
                                    $lt: ['$$order.start_date', ISODate('2019-04-22 23:50:00')]
                                }
                            ]
                        },
                        {
                            $and: [{
                                    $gte: ['$$order.start_date', ISODate('2019-04-22 23:14:00')]
                                },
                                {
                                    $lt: ['$$order.start_date', ISODate('2019-04-22 23:50:00')]
                                }
                            ]
                        }
                    ]
                }
            }
        }
    }
}, {
    $project: {
        'name': 1,
        'useless_orders': {
            $size: '$Orders'
        }
    }
}, {
    $match: {
        'useless_orders': 0
    }
}
)
