脚本宝典收集整理的这篇文章主要介绍了php – 如何优化此数组循环，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
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'] . '</br>'; echo 'layoverInMin:' . $value['inboundInfo']['layoverInMin'] . '</br>'; // // loop echo foreach ($value['inboundInfo']['flightNumbers'] as $flightNumbers) { echo 'flightNumbers :' . $flightNumbers . '</br>'; } echo 'durationInMin:' . $value['inboundInfo']['durationInMin'] . '</br>'; echo 'localDepartureTimeStr:' . $value['inboundInfo']['localDepartureTimeStr'] . '</br>'; echo ' arrivalTime:' . $value['inboundInfo']['arrivalTime'] . '</br>'; echo ' numStops:' . $value['inboundInfo']['numStops'] . '</br>'; //// loop foreach ($value[' inboundInfo']['flightClasses'] as $flightClasses) { echo 'flightClasses name :' . $flightClasses['name'] . '</br>'; echo 'flightClasses fareClass :' . $flightClasses['fareClass'] . '</br>'; } echo 'localArrivalTimeStr:' . $value['inboundInfo']['localArrivalTimeStr'] . '</br>'; // loop echo foreach ($value[' carrier'] as $carrier) { echo 'carrier name :' . $carrier['name'] . '</br>'; echo 'carrier code :' . $carrier['code'] . '</br>'; } echo 'amount:' . $value['price']['amount'] . '</br>'; echo ' totalAmount :' . $value['price']['totalAmount'] . '</br>'; echo 'pricePErPassenger:' . $value['price']['pricePerPassenger'] . '</br>'; echo 'currencyCode: ' . $value['price']['currencyCode'] . '</br>'; echo 'totalPricePerPassenger: ' . $value['price']['totalPricePerPassenger'] . '</br>'; echo 'includesTax: ' . $value['price ']['includesTax'] . '</br>'; echo 'destinationCountryCode:' . $value[' destinationCountryCode'] . ' </br> -------- </br>'; $count++; if ($count > 2) { break; } }

在减少之前,您需要确切地了解更多来自哪里.正如您在评论中所写,您正在使用远程请求来获取数据.
为数组排序您提供的数据非常快,因此我假设您不需要优化数组排序,而只需要从远程获取数据的方式和方式.一种方法是缓存它或预取它或进行并行处理.但到目前为止的细节根本不重要,除非你已经发现更多来自哪里,以便明确什么是大时间的责任所以可以考虑减少它.
希望到目前为止这是有用的,并随意添加缺少的信息到您的问题.
