![]() ![]() PHP is a server-side scripting language for creating your website’s backend system that can serve webpages, communicate with databases, and exchange data over the internet. A decent backend framework like PHP needs to be capable of providing and processing data in any format (e.g., XML, JSON, etc.) to be socially accepted in a society of skilled web development frameworks. Since JSON is a ubiquitous data format for sharing and storing data, it is vital that a PHP backend allows processing of JSON data. This is where json_encode (and json_decode) come into the picture and enable PHP processed data to be compatible with frameworks and systems that deal with JSON data and make way for easier and faster web development. In the event of a failure to decode, jsonlasterror() can be used to determine the. In this post, we’ll learn about the JSON format, about the json_encode() function - what it is, why it is required, and how it can be used to convert PHP data structures into JSON format, all with examples. Takes a JSON encoded string and converts it into a PHP variable. ![]() What is the JSON_Encode Function? What is JSON? In the end, we’ll also see how we can decode JSON data to be able to process it. JSON (JavaScript Object Notation) is one of the most popular open-standard file formats used for storing and sharing data. It uses human-readable text to represent data using attribute-value pairs and array data types. This is what a common JSON object looks like. We’ll be using this example in the sections below to understand how we can encode PHP data into JSON format. You can use the PHP jsondecode () function to convert the JSON encoded string into appropriate PHP data type. JSON allows us to represent and encapsulate complex data in an organized fashion that can be shared easily across the internet. Decoding JSON data is as simple as encoding it. Even though JSON derives its name from JavaScript, JSON was created to be used by all programming languages. ![]() Let’s see how we can convert our PHP variables into JSON format. Json_encode() is a native PHP function that allows you to convert PHP data into the JSON format. The function takes in a PHP object ($value) and returns a JSON string (or False if the operation fails). ![]()
