Creating a RESTful API in PHP to interact with a MySQL database involves several steps. Here's a basic guide to get you started:

Set Up Your Environment: Make sure you have PHP and MySQL installed on your server. You can use a local development environment like XAMPP, WAMP, or MAMP for testing. Create a MySQL Database: Create a database and tables as per your requirements. For example, let's say you have a table named users with columns id, name, and email. PHP Files Structure: Create a directory structure for your PHP files. For example: arduino Copy code /api ├── config.php ├── db.php ├── user.php └── .htaccess Set Up Database Connection (db.php): php Copy code

connect_error) { die("Connection failed: " . $conn->connect_error); } Create API Endpoints (user.php): Define CRUD operations for your API endpoints. php Copy code query($sql); if ($result->num_rows > 0) { $users = array(); while ($row = $result->fetch_assoc()) { $users[] = $row; } echo json_encode($users); } else { echo json_encode(array('message' => 'No users found.')); } } // Other CRUD operations (POST, PUT/PATCH, DELETE) can be similarly implemented Handle CORS (config.php): Add CORS headers to allow cross-origin requests. php Copy code
