Adding data to json with PHP

Depending on what parameters you passed in json_decode()

, you got either an object or an array from it, and you can add elements to them just like any other object or array.

Add $key => $element

to array:

$myArray[$key] = $element;

      

        
        
        
      

    

Slightly less obvious, but you can add a new public member to an object in PHP like this:

$myObj->$key = $element;

      

        
        
        
      

    

This will add a member variable from the contents of the $ key (assuming the $ key is a string).

If you then pass your array / object in json_encode()

, you get the following json:

{ 'value_of_key' : 'value_of_element' }
