javascript - understanding about returing two object lists by json_encode when one object list is already in json format -


I am using Ajax to get the Facebook comments of a post, so that the following php function calls the AJAX call For data returns by json encoding echo json_encode (array ($ JsonData, $ arr2)); Die ();

But the content in $ JsonData is already in json format because I think that getting the data of those comments on the Facebook post using the server side graph API call in the php function And the first $ JsonData has been assigned to echo before.

But I can not find the data on the Ajax success function 

  success: functions (data, textstats, XMLHTPRAEvieve) {var Comment = data [0] .data; Warning (comment); // shows some undefined   
 (as I was getting data like this when I was sending back the data of comments in the PPP function, thus resonating $ JsonData and Comment data in the success function = Data data)  
 So now I need to get an array $ arr2 by AJAX call so that json_encode will return the data with the array ($ JsonData, $ arr2), not working As is doing $ JsonData is already in JSON format Jason encoding in A server side may cause problems.  
 But if I juse jquery json parse the following jQuery.parseJSON (data [0]); So I comment in my way = jQuery.parseJSON (data [0]). get data.  
 If parseJson does not work on all jquery versions, then by other means I can escape from consumer call from json_encode timeline $ JsonData is already in json format and things to work in success function Brings back FII I used "Jason" as a type of data type in AJAX call.  
  
 
 
 Another method would be to decode json before combining it with your other data:  
  Echo json_encode (array (json_decode ($ JsonData), $ arr2)); Make your own Jason in this way:  
  echo '[' $ JsonData ',' Json_encode ($ arr2)   
 ']';   
 The array resonates with 2 objects in them.

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' . Before changing the state, the state is set to 'separate', but calling attachments () causes the same error to be thrown away. I am using EF 6.
