In PHP content management, how do I expose a REST API?

In PHP content management systems, exposing a REST API can help you create a flexible architecture that allows different clients (like web apps and mobile apps) to interact with your server. By implementing a RESTful API, you can enable CRUD (Create, Read, Update, Delete) operations for your data.

         1, "name" => "Item 1"],
            ["id" => 2, "name" => "Item 2"],
            ["id" => 3, "name" => "Item 3"],
        ];
        
        // Handle REST requests
        $method = $_SERVER['REQUEST_METHOD'];
        
        switch ($method) {
            case 'GET':
                // Provide the data as JSON
                echo json_encode($data);
                break;
            case 'POST':
                // Here we would handle a new item creation
                // For example purposes, we will just return a success message
                echo json_encode(["message" => "Item created successfully."]);
                break;
            case 'PUT':
                // Typically used to update existing items
                echo json_encode(["message" => "Item updated successfully."]);
                break;
            case 'DELETE':
                // Handle item deletion
                echo json_encode(["message" => "Item deleted successfully."]);
                break;
            default:
                echo json_encode(["message" => "Method not allowed."]);
                break;
        }
        ?>
