数据库是mysql数据库 类型是 mediumtext 字段名称是erpaa 表的名称是 erpbiao
现在的数据是

现在想通过更改后想变成

先用json_decode得到对象，然后再动态加上erp_store_stock数据，在json_encode生成下面的内容格式。
而且erp_store_stock和erpaa中哪个数据进行关联的？需要通过erpaa中关联的数据读取数据库得到erp_store_stock的内容。
示例代码如下
<?php
function getRS($conn,$sql,$field=""){
$q=mysqli_query($conn,$sql);
if($field==""){
return mysqli_fetch_all($q,MYSQLI_ASSOC);
}
else{
$rs=mysqli_fetch_assoc($q);
return $rs[$field];
}
return $rs;
}
$conn=mysqli_connect("localhost","root","123456","test");
$erpaa=getRS($conn,"select erpaa from erpbiao where id=3","erpaa");
$obj=json_decode($erpaa);
$id= $obj->chain_shop_info->id;//如果是其他节点下的id值注意改这里
$rs=getRS($conn,"select * from erpbb where id=$id");//读取erbb中id值一样的记录
$obj->erp_store_stock=$rs;//增加erp_store_stock属性存储erbb中对应的集合
mysqli_close($conn);
$s=json_encode($obj);//得到json字符串
echo $s;
?>
