php⼤数组循环优化,php–如何优化此数组循环我有阵列，其中包含许多航班的信息.我只想要五个最低的价格. ⾸先，我按循环进⾏循环排序.
第⼆个我打印前五个阵列
foreach ($flights_result->json_data['response']['itineraries'] as $key => $value)
{
$mid[$key] = $value['price']['totalAmount'];
}
//Sort the data with mid descending
//Add $data as the last parameter, to sort by the common key
array_multisort($mid, SORT_ASC, $flights_result->json_data['response']['itineraries']);
// print 5 arrays
foreach ($flights_result->json_data['response']['itineraries'] as $value)
{
echo 'departureTime:' . $value['inboundInfo']['departureTime'] . '';
echo 'layoverInMin:' . $value['inboundInfo']['layoverInMin'] . '';
// // loop echo
foreach ($value['inboundInfo']['flightNumbers'] as $flightNumbers)
{
echo 'flightNumbers :' . $flightNumbers . '';
}
echo 'durationInMin:' . $value['inboundInfo']['durationInMin'] . '';
echo 'localDepartureTimeStr:' . $value['inboundInfo']['localDepartureTimeStr'] . '';
echo ' arrivalTime:' . $value['inboundInfo']['arrivalTime'] . '';
echo ' numStops:' . $value['inboundInfo']['numStops'] . '';
loop
foreach ($value[' inboundInfo']['flightClasses'] as $flightClasses)
{
echo 'flightClasses name :' . $flightClasses['name'] . '';
echo 'flightClasses fareClass :' . $flightClasses['fareClass'] . '';
}
echo 'localArrivalTimeStr:' . $value['inboundInfo']['localArrivalTimeStr'] . '';
// loop echo
foreach ($value[' carrier'] as $carrier)
{
echo 'carrier name :' . $carrier['name'] . '';
echo 'carrier code :' . $carrier['code'] . '';
}
echo 'amount:' . $value['price']['amount'] . '';
echo ' totalAmount :' . $value['price']['totalAmount'] . '';
echo 'pricePerPassenger:' . $value['price']['pricePerPassenger'] . '';
echo 'currencyCode: ' . $value['price']['currencyCode'] . '';
echo 'totalPricePerPassenger: ' . $value['price']['totalPricePerPassenger'] . ''; echo 'includesTax: ' . $value['price ']['includesTax'] . '';
echo 'destinationCountryCode:' . $value[' destinationCountryCode'] . ' -------- '; $count++;
if ($count > 2)
{
break;
}
}
