如何在格式打印JSON数组数据

Question

让我来解释我想要什么。 我有两个表名：grocery_product和grocery_attribute： grocery_product字段

id 
    pname 
    categoryid 
    subcatid 

grocery_attribute字段

id 
    product_id 
    price 
    discount 

PHP代码： 这是我API代码

case "product_lists": 
    $query = "select grocery_product.id as pid,grocery_product.pname,grocery_product.categoryid,grocery_product.subcatid,grocery_attribute.id as atribid, grocery_attribute.product_id,grocery_attribute.price,grocery_attribute.discount,from grocery_product 
    right join grocery_attribute on grocery_attribute.product_id = grocery_product.id order by pid asc" ; 
    $result = $link->query($query) or die('Errant query: '.$query); 
    $FetchArray = array(); 
    $num_rows = $result->num_rows; 
    if($result->num_rows > 0){ 
     while($row = $result->fetch_assoc()){ 
      $newData['id'] = $row['pid']; // PID as product ID 
      $newData['pname'] = $row['pname']; 
      $newData['categoryid'] = $row['categoryid']; 
      $newData['subcatid'] = $row['subcatid']; 
      $newData['attrib_id'] = $row['atribid']; 
      $newData['product_id'] = $row['product_id']; 
      $newData['price'] = $row['price']; 
      $newData['discount'] = $row['discount']; 
      array_push($FetchArray,$newData); 
     } 

      $grocerryArray=array(); 
      foreach($FetchArray as $detail){ 

      $grocerryArray[$detail['id']]['id']=$detail['id']; 
      $grocerryArray[$detail['id']]['pname']=$detail['pname']; 
      $grocerryArray[$detail['id']]['categoryid']=$detail['categoryid']; 
      $grocerryArray[$detail['id']]['subcatid']=$detail['subcatid']; 
             // Get all grocerry_attribute data where grocery_attribute.product_id = grocery_product.id 
             $grocerryArray[$detail['id']]['details'][]=array(
              'attrib_id'=>$detail['attrib_id'], // attrib_id is grocery_attribute_id 
              'product_id'=>$detail['product_id'], 
              'price'=>$detail['price'], 
              'discount'=>$detail['discount'] 
             ); 
      } 
     header('Content-type: application/json'); 
     echo json_encode(array('Status'=>'Success', 'data'=>$grocerryArray, 'message'=>'You have successfully retrieved data'));break; 

当前输出是

{ 
"Status":"Success", 
"data":{ 
     "1": 
     { 
      "id":"1", 
      "pname":"Royal Moong Dal Moong Dal", 
      "categoryid":"4", 
      "subcatid":"3", 
       "details":[ 
          {"attrib_id":"1","product_id":"1","price":"500","discount":"15"}, 
          {"attrib_id":"2","product_id":"1","price":"800","discount":"10"}, 
          {"attrib_id":"3","product_id":"1","price":"1100","discount":"20"} 
         ] 
     }, 

     "2": 
      { 
       "id":"2", 
       "pname":"Royal Toor Dal/Arhar Dal/Tuver Dal", 
       "categoryid":"4", 
       "subcatid":"3", 
        "details":[ 
          {"attrib_id":"4","product_id":"2","price":"500","discount":"10"}, 
          {"attrib_id":"5","product_id":"2","price":"50","discount":"10"} 
         ] 
      } 
    }, 
    "message":"You have successfully retrieved data" 
    } 

什么我找

[ 
{ 
    "status":"success", 
    "data":[ 
     { 
      "id":"1", 
      "pname":"Royal Moong Dal Moong Dal", 
      "categoryid":"4", 
      "subcatid":"3", 
      "details":[ 
        {"attrib_id":"1","product_id":"1","price":"500","discount":"15"}, 
        {"attrib_id":"2","product_id":"1","price":"800","discount":"10"}, 
        {"attrib_id":"3","product_id":"1","price":"1100","discount":"20"} 
       ] 
     } 

     { 
     "id":"2", 
     "pname":"Royal Toor Dal\/Arhar Dal\/Tuver Dal", 
     "categoryid":"4", 
     "subcatid":"3", 
      "details":[ 
        {"attrib_id":"4","product_id":"2","price":"500","discount":"10"}, 
        {"attrib_id":"5","product_id":"2","price":"50","discount":"10"} 
       ] 
     } 


     ], 
     "message":"You have successfully retrieved data" 
} 
]

请与下面的代码替换。 array_values将被重置为数组的索引。

case "product_lists": 
    $query = "select grocery_product.id as pid,grocery_product.pname,grocery_product.categoryid,grocery_product.subcatid,grocery_attribute.id as atribid, grocery_attribute.product_id,grocery_attribute.price,grocery_attribute.discount,from grocery_product 
    right join grocery_attribute on grocery_attribute.product_id = grocery_product.id order by pid asc" ; 
    $result = $link->query($query) or die('Errant query: '.$query); 
    $FetchArray = array(); 
    $num_rows = $result->num_rows; 
    if($result->num_rows > 0){ 
     while($row = $result->fetch_assoc()){ 
      $newData['id'] = $row['pid']; // PID as product ID 
      $newData['pname'] = $row['pname']; 
      $newData['categoryid'] = $row['categoryid']; 
      $newData['subcatid'] = $row['subcatid']; 
      $newData['attrib_id'] = $row['atribid']; 
      $newData['product_id'] = $row['product_id']; 
      $newData['price'] = $row['price']; 
      $newData['discount'] = $row['discount']; 
      array_push($FetchArray,$newData); 
     } 

      $grocerryArray=array(); 
      foreach($FetchArray as $detail){ 

      $grocerryArray[$detail['id']]['id']=$detail['id']; 
      $grocerryArray[$detail['id']]['pname']=$detail['pname']; 
      $grocerryArray[$detail['id']]['categoryid']=$detail['categoryid']; 
      $grocerryArray[$detail['id']]['subcatid']=$detail['subcatid']; 
             // Get all grocerry_attribute data where grocery_attribute.product_id = grocery_product.id 
             $grocerryArray[$detail['id']]['details'][]=array(
              'attrib_id'=>$detail['attrib_id'], // attrib_id is grocery_attribute_id 
              'product_id'=>$detail['product_id'], 
              'price'=>$detail['price'], 
              'discount'=>$detail['discount'] 
             ); 
      } 
     header('Content-type: application/json'); 
     echo json_encode(array('Status'=>'Success', 'data'=>array_values($grocerryArray), 'message'=>'You have successfully retrieved data'));break;

所有你需要的是从你的结果数组中删除钥匙。 尝试PHP array_values（），例如

echo json_encode（array（'Status'=>'Success'，'data'=> array_values（$ grocerryArray），'message'=>'您已成功检索数据'） ）;打破;
