The output of the above example will look something like this: array(4) { ["Peter"]=> int(65) ["Harry"]=> int(80) ["John"]=> int(78) ["Clark"]=> int(90) } Now let's check out an example that will show you how to decode the JSON data and access individual elements of the JSON object or array in PHP.
