優化php排序功能

我從服務器得到了json響應（發佈如下）。爲了比較具有給定時間值的視頻的持續時間，目前我正在使用foreach循環分析每個object->duration的results數組。我有2個問題：優化php排序功能

是否有任何快速的方法來計算持續時間> 3600例如（而不是foreach方法）的對象？
目前使用以下if（內部foreach循環）項合併爲一個陣列：
```
 if ($duration >= $minDuration) { 
      $result [] = $tempResult; 
```
其中（$tempResult;是results的當前對象）的任何快速的方式來接與來自陣列右持續時間的所有項目併合併成$result []？提前

這裏

THX是JSON：

@ChrisLaplante我var_dumped從服務器的JSON響應值 – heron

對不起，我誤解。但是，發佈JSON本身，而不是var_dump會更有幫助。 –

你做正確。雖然您可以使用for循環而不是foreach並獲得幾微秒，但我不擔心這一點。你顯然是在下載一個json文件，所以如果你的文件非常大，'for'對'foreach'造成了很大的影響，你可能不會下載它。分配結果也是一樣。您正在製作每個匹配的副本並將其添加到新數組中 - 在大數據情況下，您可能會擔心內存使用情況，在這種情況下，您將使用for循環並跟蹤結果數組中的每個匹配的索引並從那裏出發。但是，再次，如果你正在處理下載一個json文件，我懷疑你會遇到上述任何一個問題，我會保持原樣。

}); 

$count = count($results);
