![]() ![]() ![]() Our first example is to find all people who owns a 'Tesla' from our sample JSON. ![]() Now we learn how to search a nested JSON for a specific value.

JSON is not an array, an object, or a data structure. json and place this countries.json file inside folder. This is how it will look in the database: We have only one problem.

Let's look at some examples for accessing data a nested JSON document like below. One method is to use recursion just like you access data from a nested array or tree data structure. JSON objects are key-value pairs and there are different methods you can use to access JSON objects from a nested JSON document. How to encode an associative array into a JSON object: 35, 'Ben'>37, 'Joe'>43) echo jsonencode (age) > Run Example » Definition and Usage The jsonencode () function is used to encode a value to JSON format.PHP 5.A JSON document can have JSON objects nested inside other JSON objects.
