如何访问此API返回值

Question

能帮我吗？我需要知道如何使用PHP通过API调用访问此响应的值。

Array（[queryIds] => Array（[0] => lHLLapn7EH）[timedOutRealtimeData] => [realtimeDataMissing] => [cacheFreshness] => FRESH [prunedResult] => [novaCost] => 0 [novaRequestDuration] = > 19 [wasCached] => 1 [minSampleRate] => 1 [timeComputed] => 1558794556710 [novaRuntime] => 199 [hitChunkGroupByLimit] => [throttleTime] => 0 [data] => Array（[series] => Array （[0] =>数组（[0] =>数组（[setId] => [value] => 843）））[1] => Array（[0] => Array（[setId] => [value] => 22）））[seriesLabels] =>数组（[0] =>数组（[0] => 0 [1] => C5241; GB）[1] =>数组（[0] => 0 [1 ] => C9999; GB））[seriesMeta] =>数组（[0] =>数组（[eventGroupBys] =>数组（[0] => C5241 [1] => GB）[segmentIndex] => 0 [eventIndex ] => 0 [eventGroupBy] => C5241; GB）[1] =>数组（[eventGroupBys] =>数组（[0] => C9999 [1] => GB）[segmentIndex] => 0 [eventIndex] = > 0 [eventGroupBy] => C9999; GB））[seriesCollapsed] =>数组（[0] =>数组（[0] =>数组（[setId] => [value] => 843））[1] = >阵列（[0] =>数组（[setId] => [value] => 22）））[xValues] =>数组（[0] => 2019-05-25））[partialMergedAndNewUserInformation] => [transformationIds] = >数组（[0] => 2696）[后端] => novaV2）

您可以使用

访问它们

 Array ( [0] => C9999 [1] => GB )  -> $arr['data']['seriesMeta'][0]['eventGroupBys']

Array ( [setId] => [value] => 20) -> $arr['data']['seriesMeta'][0][0]
