To develop with ThinkPHP, you can follow these steps:

1. Download ThinkPHP framework: You can download the latest ThinkPHP framework from the official website (https://www.thinkphp.cn/).

2. Configure the environment: Unzip the ThinkPHP framework to the website root directory of the server, and set the database and other related information in the configuration file.

3. Create a controller: Create a new controller in the ThinkPHP controller directory and define different methods to handle different requests.

4. Create a model: Create a new model in the ThinkPHP model directory to handle database operations.

5. Create a view: Create a new view in the view directory of ThinkPHP to display the content of the page.

6. Define routing: Define routing rules in the ThinkPHP routing configuration file to direct requests to the corresponding controllers and methods.

7. Write business logic: Write corresponding business logic in the controller, including data processing, database operations, etc.

8. Render the view: Call the corresponding model and view in the controller and pass the data to the view for display.

9. Run the program: enter the corresponding URL in the browser, trigger the corresponding routing rules, and execute the corresponding controller and method.

10. Debugging and optimization: Debug and optimize the program according to the actual operation situation to improve performance and stability.

The above are the basic steps for development using ThinkPHP. The specific development process and methods can be adjusted and expanded according to the needs and actual conditions of the project.

Here is an example:

For example, we can use thinkPHP to develop a simple blog system.

First, we need to install the thinkPHP framework on the server. Then, in the thinkPHP root directory, we create an application named "blog".

In the "blog" application, we can create a controller named "Index" that is used to handle the homepage of the blog system.

```
namespace appblogcontroller;

use thinkController;

class Index extends Controller
{
    public function index()
    {
// Get blog list data, assuming the data is stored in the database
        $blogs = db('blog')->select();

// Render the template and pass the blog data to the template
        return $this->fetch('index', ['blogs' => $blogs]);
    }

    public function detail($id)
    {
// Get blog details based on blog ID, assuming the data is stored in the database
        $blog = db('blog')->find($id);

// Render the template and pass the blog data to the template
        return $this->fetch('detail', ['blog' => $blog]);
    }
}
```

Then, we create two template files in the view directory of the "blog" application, namely "index.html" and "detail.html". These two template files are used to display the blog list and blog details respectively.

The contents of "index.html" might look like this:

```
{% for blog in blogs %}
    <h2>{{ blog.title }}</h2>
    <p>{{ blog.content }}</p>
    <p><a href="{{ url('blog/index/detail', ['id' =&gt; blog.id]) }}"&gt;View details</p>
{% endfor %}
```

The contents of "detail.html" might look like this:

```
<h2>{{ blog.title }}</h2>
<p>{{ blog.content }}</p>
```

Finally, in the routing configuration file, we point the "/" route to the "blog/Index/index" method and the "/detail/:id" route to the "blog/Index/detail" method.

After completing the above steps, we can access the homepage of the blog system, display the blog list on the homepage, and click to view the blog details.

This is just a simple example. In actual development, we can also use thinkPHP's model, validation, cache and other functions to further improve the blog system.
