It allows you to structure data neatly and send it to the front end for use in applications. If you’re facing issues while trying to achieve this, you're not alone! Let's break down the problem and see how you can implement a dynamic JSON array fetching data from your MySQL database. Understanding the Problem You may have a situation where you've fetched records from a database but only managed to create a JSON array for a single record. The challenge is to expand this capability so that the JSON array can accommodate multiple records effectively. Example of Desired Output Ideally, you want your JSON to look like this: [[See Video to Reveal this Text or Code Snippet]] How to Create the Dynamic JSON Array Let's walk through the steps you'll need to follow to generate your dynamic JSON array correctly. Step 1: Setting Up the Database Query You start by executing a SQL query to fetch data from the storie table based on certain criteria. Here’s a summarized piece of your original code: [[See Video to Reveal this Text or Code Snippet]] Step 2: Looping Through Records After running the query, you'll loop through each record returned. This is crucial for building your JSON array appropriately. [[See Video to Reveal this Text or Code Snippet]] Step 3: Adding Records to the JSON Array This is where you might have faced issues. Instead of trying to set a single record in the array for every iteration, you should append each record to the storie array using [].

By replacing a single assignment with an array append, you've made your code capable of handling multiple entries, which is essential in today’s data-driven applications. Now, you can effectively manage data communication between your backend and frontend, making it a breeze to build interactive web applications. Keep experimenting with PHP and JSON, and you'll unlock even greater capabilities in your development journey!
