Json数据到PHP [重复]

Question

我得到一个包含以下数据的 JSON 文件：

{
    "Meta Data": {
        "1. Information": "Daily Prices (open, high, low, close) and Volumes",
        "2. Symbol": "GE",
        "3. Last Refreshed": "2018-12-14 16:00:04",
        "4. Output Size": "Compact",
        "5. Time Zone": "US/Eastern"
    },
    "Time Series (Daily)": {
        "2018-12-14": {
            "1. open": "7.0800",
            "2. high": "7.2500",
            "3. low": "6.9950",
            "4. close": "7.1000",
            "5. volume": "128766603"
        },
        "2018-12-13": {
            "1. open": "7.4900",
            "2. high": "7.5000",
            "3. low": "7.1200",
            "4. close": "7.2000",
            "5. volume": "207038918"
        },
        "2018-12-12": {
            "1. open": "6.8400",
            "2. high": "7.0250",
            "3. low": "6.7000",
            "4. close": "6.7100",
            "5. volume": "105819951"
        },
        "2018-12-11": {
            "1. open": "7.0400",
            "2. high": "7.1300",
            "3. low": "6.6600",
            "4. close": "6.7600",
            "5. volume": "124580597"
        },
        "2018-12-10": {
            "1. open": "6.9700",
            "2. high": "7.1200",
            "3. low": "6.7500",
            "4. close": "6.9300",
            "5. volume": "112841778"
        }

我想检索 PHP 文件中的数据以显示股票开盘价、最高价、最低价、收盘价、成交量，如下表所示。

我试过了：

$stockurl="http://alphavantage.co/…"; 
$json = file_get_contents($stockurl); 
$obj1 = json_decode($json); 
$obj =$obj1->{'Time Series (Daily)'}; 
$date = "2018-12-14"; 
$dataForSingleDate = $obj->{$date}; 
echo $dataForSingleDate->{'1. open'}.'<br/>'; 
echo $dataForSingleDate->{'2. high'}.'<br/>'; 
echo $dataForSingleDate->{'3. low'}.'<br/>'; 
echo $dataForSingleDate->{'4. close'}.'<br/>'; 
echo $dataForSingleDate->{'5. volume'}.'<br/>'; 

但我需要手动添加日期，这就是问题。

Answer 1

$output = json_decode($your_json_array,'true'); 

这将返回关联数组对象，以便您轻松循环。
