我有一組DATA，我只想拿最後一組

DATA:

$data_val = {"001":{"data_1_1":["content1_1,content1_2"],"data_1_2":["content1_3,content1_4"]},"002":{"data_2_1":["content2_1"],"data2_2":["content2_2"]}}

我把他 JSON_decode

$data_val = JSON_decode($data_val, true);

JSON_decode DATA:

Array ( [001] => Array ( [data_1_1] => Array ( [0] => content1_1 [1] => content1_2)[data_1_2] => Array ( [0] => content1_3 [1] => content1_4) ) [002] => Array ( [data_2_1] => Array ( [0] => content2_1 [1] => content2_2  ) ) )

如果用 $data_val[002] 可以拿到

"Array ( [data_2_1] => Array ( [0] => content2_1 [1] => content2_2  )"，

我想完整的拿到這個字串是有"[002] =>" ，如下:

[002] => Array ( [data_2_1] => Array ( [0] => content2_1 [1] => content2_2  )

應該怎樣做

最佳解答

<?php
$data_val = '{"001":{"data_1_1":["content1_1,content1_2"],"data_1_2":["content1_3,content1_4"]},"002":{"data_2_1":["content2_1"],"data2_2":["content2_2"]}}';
$data_val = JSON_decode($data_val, true);

var_dump([
	end(array_keys($data_val)) => end($data_val)
]);

輸出是

array(1) {
  ["002"]=>
  array(2) {
    ["data_2_1"]=>
    array(1) {
      [0]=>
      string(10) "content2_1"
    }
    ["data2_2"]=>
    array(1) {
      [0]=>
      string(10) "content2_2"
    }
  }
}

不太清楚你的目的，但硬做的話就是這樣
覺得有點臭就是了哈哈
