Merging two json in PHP

I have two json’s

First one is

    [{"COLUMN_NAME":"ORDER_NO","COLUMN_TITLE":"Order Number"}
,{"COLUMN_NAME":"CUSTOMER_NO","COLUMN_TITLE":"Customer Number"}]

JavaScript
​x
 
    [{"COLUMN_NAME":"ORDER_NO","COLUMN_TITLE":"Order Number"},{"COLUMN_NAME":"CUSTOMER_NO","COLUMN_TITLE":"Customer Number"}]​

Second one is

[{"COLUMN_NAME":"ORDER_NO","DEFAULT_VALUE":"1521"},
{"COLUMN_NAME":"CUSTOMER_NO","DEFAULT_VALUEE":"C1435"}]

JavaScript
 
[{"COLUMN_NAME":"ORDER_NO","DEFAULT_VALUE":"1521"},{"COLUMN_NAME":"CUSTOMER_NO","DEFAULT_VALUEE":"C1435"}]​

I want to merge them and have a json like

[{"COLUMN_NAME":"ORDER_NO","COLUMN_TITLE":"Order Number","DEFAULT_VALUE":"1521"}
,{"COLUMN_NAME":"CUSTOMER_NO","COLUMN_TITLE":"Customer Number","DEFAULT_VALUEE":"C1435"}]

JavaScript
 
[{"COLUMN_NAME":"ORDER_NO","COLUMN_TITLE":"Order Number","DEFAULT_VALUE":"1521"},{"COLUMN_NAME":"CUSTOMER_NO","COLUMN_TITLE":"Customer Number","DEFAULT_VALUEE":"C1435"}]​

is there a way to merge them? It is also OK for me if a stucture change in JSON is required

thanks.

Answer

Something like json_encode(array_merge(json_decode($a, true),json_decode($b, true))) should work.

array_merge in official PHP documentation

json_decode in official PHP documentation

EDIT: try adding true as second parameter to json_decode. That’ll convert objects to associative arrays.

EDIT 2: try array-merge-recursive and see my comment below. Sorry have to log out now 🙁 This looks like a full correct solution: https://stackoverflow.com/a/20286594/1466341
