關聯數組，將json轉換為php

Question

在我的php文件中，使用以下命令，

$obj = ($_POST['data']);
var_dump(json_decode($obj,true));

我看到了這個結果。 這是正確的格式嗎？ 以及如何訪問數組。

例如，將新變量$ newID設置為與row1 id相同

array(4) {
  ["row0"]=>
  string(92) "{"id":"157","name":"123","basic":"123123123","submitter":"Keith","status":"review"}"
  ["row1"]=>
  string(169) "{"id":"158","name":"TEST RESOURCE","basic":"Please state the type of work.","submitter":"Keith","status":"review"}"
  ["row2"]=>
  string(107) "{"id":"159","name":"TEST OTHER","basic":"testing for other","submitter":"Keith","status":"review"}"
  ["row3"]=>
  string(160) "{"id":"160","name":"Name","basic":"type of work","submitter":"Keith","status":"review"}"
}

data    {"row0":"{\"id\":\"157\",\"name\":\"123\",\"basic\":\"123123123\",\"submitter\":\"Keith\",\"status\":\"review\"}","row1":"{\"id\":\"158\",\"name\":\"TEST RESOURCE\",\"basic\":\"Please state the type of work.\",\"submitter\":\"Keith\",\"status\":\"review\"}","row2":"{\"id\":\"159\",\"name\":\"TEST OTHER\",\"basic\":\"testing for other\",\"submitter\":\"Keith\",\"status\":\"review\"}","row3":"{\"id\":\"160\",\"name\":\"Name\",\"basic\":\"type of work\",\"submitter\":\"Keith\",\"status\":\"review\"}"} 

Answer 1

數組的每個“行”都是另一個JSON字符串。 數據似乎經過了雙重編碼，例如：

$array = json_encode(
    array(
        'row0' => json_encode(array('id' => '157', ...)),
        ...
    )
)

除非您要在JSON對象中使用JSON對象，否則這是編碼錯誤的數據。 要使用它，您需要再次對每個單獨的項目進行json_decode 。 更好的是：修復編碼步驟。
