这是从实时航班查询中获取的json数据。我希望能够使用[depart_at]字段来确定每次航班的停靠站数量。因此,我一直在努力获取[depart_at]字段的出现次数,以便得出每个航班的停靠点数(停留时间)。我已经使用以下代码转换为php:但是我没有得到计数。

您可以尝试这样:
$json = '{

"results": [
{
"itineraries": [
{
"outbound": {
"duration": "08:35",
"flights": [
{

echo substr_count($json, 'departs_at');

您可以尝试这种方式。
$countDepartsAt = 0;
foreach ($itinerary['outbound']['flights'] as $flight ){
if(array_key_exists('departs_at', $flight)) {
$countDepartsAt++;
}
}
echo $countDepartsAt;
