php - Assign Key to Existing Array -


Assume that I have an array like this example: 

  [{type "type And I want to specify this whole array by name as "dish" for a particular key: "food", "alias": "food"}]   
  
 How can I archive it?  
 The expected product should be something like this:  
  "dish": [{"type": "food", "nickname": "food"}]   
 I know how to create new key values ​​pairs but have never thought of assigning a key until now. 
 
 
 
  $ json = '[{"type": "food", "alias": " food "}]'; $ Data = json_decode ($ json, true); $ Data = array ('dish' = & gt; $ data); Echo json_encode ($ data);
