How can I merge multiple JSON objects in PHP?

Merging Multiple JSON Objects in PHP

Combining multiple JSON objects can be a common task in web development. In this case, you have two JSON objects and want to merge them into a single object.

To do this, you can use the array_merge function in PHP. This function takes two or more arrays as arguments and returns a new array that contains all the elements from each argument array.

In your case, you can convert your JSON objects to arrays using the json_decode function, which takes a JSON string as an argument and returns an array.

Here's an example of how you can merge your two JSON objects using array_merge and json_decode:

$json1 = '[{"COLUMN_NAME":"ORDER_NO","COLUMN_TITLE":"Order Number"},
{"COLUMN_NAME":"CUSTOMER_NO","COLUMN_TITLE":"Customer Number"}]';

$json2 = '[{"COLUMN_NAME":"ORDER_NO","DEFAULT_VALUE":"1521"},
{"COLUMN_NAME":"CUSTOMER_NO","DEFAULT_VALUEE":"C1435"}]';

$array1 = json_decode($json1, true);
$array2 = json_decode($json2, true);

$mergedArray = array_merge($array1, $array2);

$mergedJson = json_encode($mergedArray);

echo $mergedJson;

This code will output the following JSON object:

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

Which is exactly the output you were looking for.
