+#### TODO project in PHP
+
+##### PHP version
+
+```PHP 8.2.12 (cli) (```
+
+##### Run the project
+Navigate till TodoApp.php file in project and execute command
+
+```php -S localhost:8080 .\TodoApp.php ```
+
+### API Structure
+
+The Todo App CRUD API is a set of endpoints that allow users to perform CRUD (Create, Read, Update, Delete) operations on todo items in the Todo App. 
+
+The API includes the following endpoints:
+
+- `GET /todos`: Retrieves a list of all todo items.
+- `GET /todos/{id}`: Retrieves a specific todo item by its ID.
+- `POST /todos`: Creates a new todo item.
+- `PUT /todos`: Updates an existing todo item.
+- `DELETE /todos/{id}`: Deletes a todo item.
+
+Each endpoint accepts and returns JSON data.
+
+Sample CURL requests with responses for the Todo App CRUD API:
+
+1. Retrieve a list of all todo items:
+    
+    ```bash
+    curl -s http://localhost:8080/todos
+    ```
+    
+    Response:
+    
+    ```json
+    [
+    {
+        "id": 1,
+        "task": "task1",
+        "description": "",
+        "completed": false,
+        "edited": false,
+        "lastViewed": false,
+        "serialNumber": 1,
+        "createdDate": "2023-10-18T07:12:31.830Z",
+        "modifiedDate": "2023-10-18T07:12:31.830Z"
+    },
+    {

+        "task": "task2",
+        "description": "",
+        "completed": false,

+        "createdDate": "2023-10-18T07:12:34.746Z",
+        "modifiedDate": "2023-10-18T07:12:34.746Z"
+    },
+    ....
+]
+    ```
+    
+2. Retrieve a specific todo item by its ID:
+    
+    ```bash
+    curl -s http://localhost:8080/todos/{id}
+    ```
+    
+    Response:
+    
+    ```json
+   {

+    }
+    ```
+    
+3. Create a new todo item:
+    
+    ```bash
+   curl -s POST -H "Content-Type: application/json" -d '{"serialNumber": 10,"task": "task9","completed": false,"description": "","edited": false,"createdDate": "2023-10-06T10:41:11.806Z","modifiedDate": "2023-10-06T10:41:11.806Z","lastViewed": false}' http://localhost:8080/todos
