从JSON对象获取最大值(Get largest value from JSON object)

从JSON对象获取最大值(Get largest value from JSON object)

我有一个从cURL中检索到的$string ，如下所示：

{"time":0.01,"total_rows":7,"rows":[{"id":968},{"id":969},{"id":970},{"id":971},{"id":972},{"id":973},{"id":974}]}

我想知道如何获得具有最大值的id （即974），我该如何在PHP中执行此操作？

I have a $string retrieved from cURL like this:

{"time":0.01,"total_rows":7,"rows":[{"id":968},{"id":969},{"id":970},{"id":971},{"id":972},{"id":973},{"id":974}]}

I would like to know how to get the id that has the largest value (i.e 974), how can I do this in PHP?

最满意答案

$result = '{"time":0.01,"total_rows":7,"rows":[{"id":968},{"id":969},{"id":970},{"id":971},{"id":972},{"id":973},{"id":974}]}'; $json = json_decode($result,true); $max = max($json["rows"]); echo $max["id"]; // "974" $result = '{"time":0.01,"total_rows":7,"rows":[{"id":968},{"id":969},{"id":970},{"id":971},{"id":972},{"id":973},{"id":974}]}'; $json = json_decode($result,true); $max = max($json["rows"]); echo $max["id"]; // "974"
