Introduction

In this tutorial, we will learn how to fetch data from a JSON file and parse it using PHP. We will also display the parsed data in an HTML unordered list. This process involves creating a JSON file with an array of movies, then using PHP to extract and decode the JSON data. Finally, we will display the movie information in an HTML format.

Setting up the Server

To begin, we need a server to run our PHP code. We recommend using XAMPP, WAMP, or MAMP, depending on your operating system. If you already have a PHP-enabled web hosting provider or server, you can use that as well. Once you have your server set up, navigate to the htdocs folder. If You are using XAMPP, the path is typically C:\xampp\htdocs. Create a new folder called "movies" and inside it, create two files: "movies.json" and "index.php".

Creating the JSON File

Open the "movies.json" file using a text editor, such as Sublime Text. JSON (JavaScript Object Notation) is a data interchange format used for storing structured data. We will define an array called "movies" and populate it with objects representing different movies. Each movie object will have properties such as title, year, genre, and director. Separate the objects with commas. Once you have defined the movie objects, you can save the file.

Parsing JSON with PHP

Open the "index.php" file and start by opening the PHP tags. We will use the file_get_contents function to extract the content from the "movies.json" file and store it in a variable called $json_data. Next, create another variable called $movies to hold the decoded version of the JSON data. We will use the json_decode function with the $json_data variable as the first argument and true as the Second argument. This will give us an array of movie objects.

Displaying Data in HTML

To display the movie information in the browser, we will use a foreach loop to iterate through each movie object in the $movies array. Within the loop, we will append the HTML tags and values to a variable called $output. We will start with an unordered list (<ul>) and then add the movie title, year, genre, and director information within list items (<li>). Finally, we will echo the $output variable to display the formatted movie information in the browser.

Adding Styling and Filters (Optional)

If desired, you can add CSS styling to the HTML structure created in the previous step. This will allow you to customize the appearance of the movie information. Additionally, you can implement filters or search functionality to make it easier for users to find specific movies from the list. However, these steps are optional and can be implemented Based on your specific requirements.

Conclusion

In this tutorial, we have learned how to fetch data from a JSON file, parse it using PHP, and display the parsed data in an HTML format. We have covered the basic steps required to retrieve and manipulate JSON data. By following these steps, you can fetch and display data from any desired JSON source using PHP.
