如何在foreach循环PHP中回显Json数据

大家好，在发送post请求后，我正在处理wego flight api，我有一个json数据数组，格式如下

{"response":{
"pendingResults":"true",
"itineraries":[
{"ecpcRank":0,"inboundInfo":{"aircraftTypes":[],"departureTime":1401116400000,"layoverInMin":0,"flightNumbers":["SQ981"],"durationInMin":85,"airportsExpanded":["BKK","SIN"],"localDepartureTimeStr":"2014/05/26 22:00 +0700","airports":["BKK","SIN"],"arrivalTime":1401121500000,"numStops":0,"flightClasses":[{"name":"Economy","fareClass":1}],"localArrivalTimeStr":"2014/05/27 00:25 +0800"},"location":[{"code":"BKK","name":"Bangkok"},{"code":"SIN","name":"Singapore Changi"}],"carrier":[{"name":"Singapore Airlines","code":"SQ"}],"bookingType":"WEBSITE","price":{"name":"","nameOTA":"","description":"","amount":"406","totalAmount":"406","pricePerPassenger":"406","currencyCode":"USD","totalPricePerPassenger":"406","includesTax":true},"generatedDate":1399013553817,"providerId":"singaporeair.com","id":"SQ974[SIN-BKK]|SQ981[BKK-SIN]","originCountryCode":"SG","bookingCode":"14859286949361958","destinationCountryCode":"TH","outboundInfo":{"aircraftTypes":[],"departureTime":1399956900000,"layoverInMin":0,"flightNumbers":["SQ974"],"durationInMin":205,"airportsExpanded":["SIN","BKK"],"localDepartureTimeStr":"2014/05/13 12:55 +0800","airports":["SIN","BKK"],"arrivalTime":1399969200000,"numStops":0,"flightClasses":[{"name":"Economy","fareClass":1}],"localArrivalTimeStr":"2014/05/13 15:20 +0700"}},

我想打印全票

下面是我的php代码

$result2=curl_exec($ch);



$data = json_decode($result2);
$data = objectToArray($data);

function objectToArray($object)
{
    if (!is_object($object) && !is_array($object)) {
        return $object;
    }
    if (is_object($object)) {
        $object = (array )$object;
    }
    return array_map('objectToArray', $object);
}


foreach($data as $root){
     foreach($root as $rootOne){
        if(is_array($rootOne)){
            foreach($rootOne as $rootArrays){
                if(!empty($rootArrays["price"])){
                $priceArray = $rootArrays["price"];
                echo $priceArray["totalPricePerPassenger"];
                echo"<hr>";
                }
            }
        }
     }
}

$result2=curl\u exec（$ch）；
$data=json_解码（$result2）；
$data=objectToArray（$data）；
函数objectToArray（$object）
{
如果（！is_对象（$object）&&！is_数组（$object））{
返回$object；
}
if（is_object（$object））{
$object=（数组）$object；
}
返回数组映射（'objectToArray'，$object）；
}
foreach（$root形式的数据）{
foreach（$root作为$rootOne）{
if（is_数组（$rootOne））{
foreach（$rootOne作为$rootarray）{
如果（！empty（$rootArrays[“price”]））{
$priceArray=$rootArrays[“price”]；
echo$priceArray[“totalPricePerPassenger”]；
回声“
”；
}
}
}
}
}

只需使用

---

将返回一个数组，您可以更灵活地回显该数组。

首先，您需要确保JSON字符串有效。为此，请使用类似的在线过梁

请注意，这里不需要任何奇特的函数，如

objectToArray（）

，因为默认情况下允许将字符串解码为数组（与对象相反）。只需将第二个参数设置为

TRUE

：

$data = json_decode($json, TRUE); // no need to use objectToArray()

然后使用以下方法检查阵列的结构：

---

错误，它重新运行object@EaterOfCode如果您提供true作为次要参数，则不会这样做。@据我所知，我建议他只使用它，而不是使用其他函数不必要的复杂程度。@TerryHiggins:第一步：通过添加到脚本顶部来启用错误报告。刷新页面。你得到了什么错误？@TerryHiggins:这意味着你没有得到数组。您的JSON字符串是什么样子的？你从哪里得到的？@TerryHiggins：注意，我只能在那个页面上看到一个错误，而不能看到实际的代码。如果你把准确的代码贴在某个地方，这样我就可以看到它，这将是非常有帮助的。现在请检查URL，我已经添加了代码too@TerryHiggins：URL中缺少API键。当您尝试在浏览器中手动加载URL时会发生什么情况？而且，你似乎没有读到答案。再读一遍。

echo '<pre>' . print_r($data, TRUE) . '</pre>;

foreach ($data['response']['itineraries'] as $itinerary) {
    echo $itinerary['price']['pricePerPassenger'] . "\n";
}
