php - 使用 php 将 mysql 数据转换为带有附加信息的 json

Question

代码

<?php
include "dbconfig.php";
include "yrsetup.php";
$tdate='2018-11-19';
$tmarket='sirsi';
$sql="SELECT ALLCODES.NAME AS Type,MIN(LOT1819.RATE) AS 
Min,MAX(LOT1819.RATE) AS Max,ROUND(SUM(LOT1819.RATE)/COUNT(LOTNO),0) AS avg 
FROM LOT1819 
    LEFT JOIN ALLCODES  ON allcodes.`sw`='IT' AND allcodes.`cd`=APCD
    WHERE MRK IS NULL AND DATE1='2018-11-19' AND LOT1819.SW IS NULL GROUP BY 
APCD";    

        $result=mysqli_query($conn,$sql);
        $response = array();
        $response = array('Date' => $tdate, 'market' => $tmarket);
        while($row=mysqli_fetch_assoc($result))
            {
                array_push($response,$row);
            }
            $outsidebrace=')';
            array_push($response,$outsidebrace);
            echo json_encode($response);
            //echo json_encode($response);
?>

结果

{"Date":"2018-11-19","market":"sirsi","0":{"Type":"RASHI","Min":"30358","Max":"32699","avg":"31505"},"1":{"Type":"BETTE","Min":"21099","Max":"29618","avg":"27110"},"2":{"Type":"MURI","Min":"23121","Max":"23809","avg":"23465"},"3":{"Type":"KOLE","Min":"18019","Max":"23558","avg":"21928"},"4":{"Type":"K.G.","Min":"14199","Max":"22609","avg":"19109"},"5":{"Type":"CHALI","Min":"24039","Max":"26488","avg":"25773"},"6":{"Type":"B.G.","Min":"16699","Max":"22300","avg":"21109"},"7":{"Type":"11-CHALI","Min":"22720","Max":"23899","avg":"23512"},"8":{"Type":"KOKA","Min":"11589","Max":"20699","avg":"16902"},"9":{"Type":"CH.KEMP","Min":"18315","Max":"24079","avg":"21862"},"10":{"Type":"ARAGERE","Min":"22809","Max":"22809","avg":"22809"},"11":{"Type":"KE.BETTE","Min":"23731","Max":"24631","avg":"24128"},"12":{"Type":"PEPPER","Min":"34699","Max":"34899","avg":"34799"},"13":{"Type":"CHAKRA","Min":"17869","Max":"23119","avg":"20494"},"14":{"Type":"BT RASHI","Min":"26899","Max":"29718","avg":"28431"},"15":{"Type":"MURI BETTE","Min":"21490","Max":"21699","avg":"21594"},"16":{"Type":"MURI RASHI","Min":"25699","Max":"25699","avg":"25699"},"17":{"Type":"CHURU","Min":"7299","Max":"18009","avg":"12654"},"18":{"Type":"LA KOKA","Min":"6199","Max":"9399","avg":"7799"},"19":{"Type":"LA B GOT","Min":"11899","Max":"18499","avg":"15666"},"20":{"Type":"DBL CHALI","Min":"26418","Max":"26418","avg":"26418"},"21":{"Type":"GOT BETTE","Min":"14099","Max":"22421","avg":"18260"},"22":{"Type":"S BETTE","Min":"29518","Max":"29518","avg":"29518"},"23":")"}

这是有效的 json，但我需要以下格式的结果

如何解决这个问题

Answer 1

您需要为数据构建一个嵌套数组，此时您将其添加到顶层...

$result=mysqli_query($conn,$sql);
$response = array('Date' => $tdate, 'market' => $tmarket
               , 'data' => array());
while($row=mysqli_fetch_assoc($result))
    {
        $response['data'][] = $row;
    }
echo json_encode($response);

因此，在设置初始 $reponse 数组时，我添加了一个带有空数组的 data 元素。然后在循环内，我将新行添加到此项(使用 [] 而不是 array_push())。

我还删除了 $outsidebrace 位，因为不需要它。
