How to Save Form Data in a JSON File Using PHP | Store Messages in JSON File with PHP

In this tutorial we are going to use PHP to collect the data from
a contact form and save the messages in a JSON file.
Also we will have an inbox page to display, delete, or reply to a message.

I am going to start the tutorial with a live example and then we are going to recreate the whole thing.
This is a full stack tutorial so we will use HTML, CSS, PHP, and JavaScript to code the application.

In this tutorial you will learn how to:
Fetch form data with PHP using the POST HTTP Request method.
Create an array from the form data.
Loop through an array and sanitize the data using the 'array_map' and 'htmlspecialchars' functions.
Use the 'file_put_contents' function to write the data to the JSON file.
Reply to an email using your operating system's email client.
Use the 'file_get_contents' functions to read data from a file.
Use the 'json_decode' and 'json_encode' functions to handle JSON data.
Display PHP error messages in the contact form.
Format the 'date' function for proper saving the date and time.
Assign 'onclick' event listeners on html buttons.
Make the form sticky, means that the form will not clear the entered values in case of an error.
