从单个列类型的另一列获取多个值

Question

我想为单个商店值检索多个offer_title，报价等，但只返回一个商品。数据库中的特定商店有多个商店优惠。怎么做？

这是我的代码：

<?php 

$sql ="SELECT * , Offer_Master.Store_id 
        FROM Store_Master_Profile 
            INNER JOIN Offer_Master 
                ON Store_Master_Profile.Store_Name = Offer_Master.Store_id 
                AND Store_Master_Profile.tag like '%Electronics%' 
        LIMIT 0 , 300 ";

require_once('Config.php');

$r = mysqli_query($con,$sql);

$result = array();

while($row = mysqli_fetch_array($r)){
    array_push($result,array(
                    'storephoto'=>$row['storephoto'],
                    'Store_Name'=>$row['Store_Name'],
                    'Store_email'=>$row['email'],
                    'City_id'=>$row['City_id'],
                    'Area_id'=>$row['Area_id'],
                    'Address'=>$row['Address'],
                    'Latitude'=>$row['Latitude'],
                    'Longitude'=>$row['Longitude'],
                    'mobile'=>$row['mobile'],
                    'Store_Feature'=>$row['Store_Feature'],
                    'tag'=>$row['tag'],
                    'storeimages'=>$row['storeimages'],
                    'workingdays'=>$row['workingdays'],
                    'fromtime'=>$row['fromtime'],
                    'totime'=>$row['totime'] ,
                    'Offer_Title'=>$row['Offer_Title'],
                    'MRP_Price'=>$row['MRP_Price'],
                    'Actual_Price'=>$row['Actual_Price'],
                    'Description'=>$row['Description'],
                    'Expiry_Date'=>$row['Expiry_Date']  
                    )
            );

}

echo json_encode(array('result'=>$result));

mysqli_close($con);
