Generate JSON File in PHP

In this article, we will introduce the method to generate a .json file in PHP.

Use file_put_contents() Function to Generate a .Json File in PHP

The built-in function file_put_contents() could write the content into a file in PHP. It searches for the file to write in, and if the desired file is not present, it creates a new file. We can use this function to create a .json file. The correct syntax to use this function is as follows

file_get_contents($pathOfFile, $info, $customContext, $mode);

This function returns the number of bytes written on the file if successful and false otherwise.

The below program will create a new .json file and store JSON data into it

php  // data strored in array  $array = Array (  "0" => Array (  "id" => "01",  "name" => "Olivia Mason",  "designation" => "System Architect"  ),  "1" => Array (  "id" => "02",  "name" => "Jennifer Laurence",  "designation" => "Senior Programmer"  ),  "2" => Array (  "id" => "03",  "name" => "Medona Oliver",  "designation" => "Office Manager"  ) );  // encode array to json  $json = json_encode($array); $bytes = file_put_contents("myfile.json", $json); echo "The number of bytes written are $bytes."; ?>

We use json_encode() function to convert the data stored in the array to a JSON string. Once the data is converted to a JSON string, file_put_contents() function creates a .json file and writes data into it. The output shows the number of bytes, which means the data is written successfully.

The number of bytes written is 207.

Tutorial: Create JSON File From MySQLi in PHP

In this tutorial, we will create a Create JSON File From MySQLi using PHP. This code can generate a JSON file from the MySQLi database when the user clicks the button. The system itself uses the PHP POST method to call a specific function that will extract the MySQLi table into a JSON file. This is a user-friendly kind of program feel free to modify it.

We will be using JSON as data management to store user data, and it will act as database storage. It is an open-standard file format that uses human-readable text to transmit data objects into the local server.

Getting Started:

First, you have to download & install XAMPP or any local server that runs PHP scripts. Here’s the link for the XAMPP server https://www.apachefriends.org/index.html .

And, this is the link for the bootstrap that I used for the layout design https://getbootstrap.com/ .

Creating Database

Open your database web server then create a database name in it db_mysqli_json ; after that, click Import, then locate the database file inside the folder of the application then click ok.

Creating the database connection

Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it conn.php.

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php.
