以下是一个简单的PHP接口实例，我们将通过一个简单的API来展示如何接收请求、处理数据并返回结果。
1. 项目结构
```
/api/
/controllers/
ExampleController.php
/models/
ExampleModel.php
/routes/
api.php
/views/
index.php
```
2. ExampleModel.php
```php
class ExampleModel {
public function getData() {
// 模拟从数据库获取数据
return ['name' => '张三', 'age' => 20];
}
}
```
3. ExampleController.php
```php
class ExampleController {
private $model;
public function __construct() {
$this->model = new ExampleModel();
}
public function index() {
$data = $this->model->getData();
return json_encode($data);
}
}
```
4. api.php
```php
require_once '../controllers/ExampleController.php';
$controller = new ExampleController();
$controller->index();
```
5. index.php
```php
require_once 'api.php';
```
6. 使用curl测试API
```bash
curl http://localhost/api/
```
7. 返回结果
```
