Step 2: Create a file named called code.php and paste below code

<?php 
include('includes/dbcon.php');
session_start();

if(isset($_POST['update_data']))
{
    $name = $_POST['name'];
    $email = $_POST['email'];
    $phone = $_POST['phone'];
    $token = $_POST['ref_token'];

    $data = [
        'name' => $name,
        'email' => $email,
        'phone' => $phone,
    ];

    $ref = "contact/".$token;
    $postdata = $database->getReference($ref)->update($data);

    if($postdata){
        $_SESSION['status'] = "Data Updated Successfully";
        header("Location: index.php");
    }else{
        $_SESSION['status'] = "Data Not Updated. Something Went Wrong.!";
        header("Location: index.php");
    }
}


Step 3: create a file for dbconnection - dbcon.php and paste the below code:


<?php
   require __DIR__.'/vendor/autoload.php';

   use Kreait\Firebase\Factory;
   use Kreait\Firebase\ServiceAccount;

   // This assumes that you have placed the Firebase credentials in the same directory
   // as this PHP file.
   $serviceAccount = ServiceAccount::fromJsonFile(__DIR__ . '/yourjsonfile.json');
   $firebase = (new Factory)
      ->withServiceAccount($serviceAccount)
      ->withDatabaseUri('yourdatabaseproject.firebaseio.com')
      ->create();
      
   $database = $firebase->getDatabase();
?>
