我从服务器收到 json 响应（发布在下面）。为了将视频的持续时间与给定的时间值进行比较，目前我正在使用 foreach 循环分析每个object->duration数组results。我有两个问题：

  1. 例如，有没有什么快速的方法来计算持续时间 > 3600 的对象（而不是 foreach 方法）？

  2. 目前使用以下if（在 foreach 循环内）将项目合并到一个数组中：

            if ($duration >= $minDuration) {
            $result [] = $tempResult;

    where ($tempResult;是results当前对象) 有什么快速的方法可以从数组中选择所有具有正确持续时间的项目并合并到$result []？

提前谢谢

这是JSON：

你做对了。虽然您可以使用 for 循环而不是 foreach 并获得几微秒的时间，但我不会担心这一点。您显然正在下载一个 json 文件，因此如果您的文件太大以至于“for”对“foreach”产生了影响，那么您可能不会下载它。分配结果也是如此。您正在制作每个匹配项的副本并将其添加到新数组中 - 在大数据情况下，您可能会担心内存使用情况，在这种情况下您将使用 for 循环并跟踪结果数组中每个匹配项的索引然后从那里去。但是同样，如果您正在处理下载 json 文件，我怀疑您是否会遇到上述任何一个问题，我会保持原样。

对于 PHP >= 5.3：

$results = array_filter($arr, function($var) {
    return $var->duration > 3600;
});

$count = count($results);
