我目前停留在php的json格式中。我在下面给出了我的输出json。我需要做的是使当前json的格式成为所需的格式。我缺少JSON格式的数组。谁能帮我这个忙。
我用于打印json输出的代码如下:
$menuHead=array();
$i=0;
foreach($res as $key => $value){
$i=$key+1;
//$menuHead[$i]['menuHead']=$value['category'];
if(isset($menuHead[$key]['menuHead'])){
if($menuHead[$key]['menuHead']==$value['category']){
$menuHead[$key]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$key]['data'][$i]['price']=$value['price'];
$menuHead[$key]['data'][$i]['description']=$value['description'];
$menuHead[$key]['data'][$i]['itemId']=$value['id'];
$menuHead[$key]['data'][$i]['customizable']=$value['customizable'];
}else{
$menuHead[$i]['menuHead']=$value['category'];
$menuHead[$i]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$i]['data'][$i]['price']=$value['price'];
$menuHead[$i]['data'][$i]['description']=$value['description'];
$menuHead[$i]['data'][$i]['itemId']=$value['id'];
$menuHead[$i]['data'][$i]['customizable']=$value['customizable'];
}
}else{
$menuHead[$i]['menuHead']=$value['category'];
$menuHead[$i]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$i]['data'][$i]['price']=$value['price'];
$menuHead[$i]['data'][$i]['description']=$value['description'];
$menuHead[$i]['data'][$i]['itemId']=$value['id'];
$menuHead[$i]['data'][$i]['customizable']=$value['customizable'];
}
}
$final['MenuList']=$menuHead;
echo json_encode($final);
当前格式:
{
"MenuList": {
"1": {
"menuHead": "Main Course",
"data": {
"1": {
"itemName": "Chicken Thai Curry",
"price": "599",
"description": "",
"itemId": "67",
"customizable": "1"
}
}
},
"2": {
"menuHead": "Refreshments",
"data": {
"2": {
"itemName": "Kingfisher Premium",
"price": "999",
"description": "Kingfisher beer",
"itemId": "69",
"customizable": "1"
},
"3": {
"itemName": "Mocktail",
"price": "999",
"description": "",
"itemId": "68",
"customizable": "1"
}
}
},
"4": {
"menuHead": "Rice biriyani",
"data": {
"4": {
"itemName": "Dal makni risotto",
"price": "499",
"description": "Dal makhni risotto",
"itemId": "66",
"customizable": "1"
}
}
}
}
}
所需格式:
{
"menuList": [
{
"menuHead": "In Steamer (Momos)",
"data": [
{
"itemName": "Tandoori Momo",
"description": "",
"price": "150",
"itemId": "16",
"customizable": "0"
},
{
"itemName": "Fried Momo Pork",
"price": "100",
"description": "",
"itemId": "15",
"customizable": "0"
}
]
},
{
"itemName": "Rice and Noodles",
"data": [
{
"sub_category": "Tandoori Momo",
"description": "",
"price": "150",
"itemId": "16",
"customizable": "0"
},
{
"itemName": "Fried Momo Pork",
"price": "100",
"description": "",
"itemId": "15",
"customizable": "0"
}
]
}
]
}
原始响应如下:

如果要使用与JavaScript兼容的数组,则索引必须从0开始。最简单的方法是使用array_values()
:
$final['MenuList'] = array_values($menuHead);
答案 1 :(得分:2)
问题在于,当您添加data
项时,您需要添加它们而没有特定的键,就像使用$i
进行添加一样,
$menuHead[$key]['data'][$i]['itemName']=$value['sub_category'];
这将阻止它们成为您希望的常规数组。对于json_encode()
,数组必须从0开始并且必须是连续的,以使其成为数组。
而是一次性创建它们,然后使用[]
...将它们添加到现有数据的末尾。
$menuHead[$key]['data'][] = ['itemName' =>$value['sub_category'],
'price'=> $value['price'],
'description'=>$value['description'],
'itemId'=>$value['id'],
'customizable'=>$value['customizable']];
这需要使用每组相似的代码来完成,其中包括整个数组本身,可以使用
$final['MenuList'] = array_values($menuHead);
要尝试修复已拥有的数据,这意味着除了添加以下代码外没有其他更改...
foreach ( $menuHead as $menu ) {
$menu['data'] = array_values($menu['data']);
}
$final['MenuList'] = array_values($menuHead);

使用array_values();
我修复了您的代码,它应该可以工作
$menuHead=array();
$i=0;
foreach($res as $key => $value){
$i=$key+1;
//$menuHead[$i]['menuHead']=$value['category'];
if(isset($menuHead[$key]['menuHead'])){
if($menuHead[$key]['menuHead']==$value['category']){
$menuHead[$key]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$key]['data'][$i]['price']=$value['price'];
$menuHead[$key]['data'][$i]['description']=$value['description'];
$menuHead[$key]['data'][$i]['itemId']=$value['id'];
$menuHead[$key]['data'][$i]['customizable']=$value['customizable'];
}else{
$menuHead[$i]['menuHead']=$value['category'];
$menuHead[$i]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$i]['data'][$i]['price']=$value['price'];
$menuHead[$i]['data'][$i]['description']=$value['description'];
$menuHead[$i]['data'][$i]['itemId']=$value['id'];
$menuHead[$i]['data'][$i]['customizable']=$value['customizable'];
}
}else{
$menuHead[$i]['menuHead']=$value['category'];
$menuHead[$i]['data'][$i]['itemName']=$value['sub_category'];
$menuHead[$i]['data'][$i]['price']=$value['price'];
$menuHead[$i]['data'][$i]['description']=$value['description'];
$menuHead[$i]['data'][$i]['itemId']=$value['id'];
$menuHead[$i]['data'][$i]['customizable']=$value['customizable'];
}
}
// i'am use array_values()
$final['MenuList']= array_values($menuHead);
echo json_encode($final);
