Parsing JSON with PHP

When working with APIs that return data in JSON format, it's essential to know how to parse and retrieve specific information from the JSON structure. This guide will demonstrate techniques for parsing JSON data in PHP, with a focus on extracting specific fields such as title, brand, and availability.

By default, json_decode() returns an object. However, to work with multi-dimensional arrays, it's recommended to decode the JSON as an array using the true argument:

<code class="php">$json = json_decode($data, true);</code>
Copy after login

Retrieving Specific Fields

<code class="php">foreach ($json['items'] as $item) {</code>
