ThinkPHP is an open source PHP framework that provides some modern development functions, such as MVC architecture, database access, template engine, cache management, etc. In the latest ThinkPHP5 version, developers can call related functions more conveniently to improve development efficiency.

Below we will introduce in detail how to call methods in ThinkPHP5.

1. Method calls in the controller

The controller is the place in the application that processes HTTP requests and sends responses to the browser. Controllers in ThinkPHP5 are mainly located in the app directory. The naming rule for controllers is camel case, for example: UserController.php. In the controller, we can define multiple methods to respond to different requests. Method names also use camelCase naming, for example: indexAction().

To call the method in the controller, you need to access it through the URL. The domain name and port number in the URL are followed by the name of the controller, for example: http://example.com/UserController. To access methods in the controller, you need to add the method name after the URL, for example: http://example.com/UserController/index.

In the controller method, we can use some built-in functions to obtain the parameters of the HTTP request, access the database, output templates, etc. For example, the following code demonstrates how to obtain parameters in an HTTP request:

public function index()
{
    $name = $this->request->param('name');
    $age = $this->request->param('age');
    echo "姓名：".$name."<br>年龄：".$age;
}

2. Method calls in the model

The model is the place in the application responsible for managing data. The model in ThinkPHP5 is located in the model directory under the app directory. The naming rule for the model is camel case, for example: UserModel.php.

In the model, we can define multiple methods to manage data. Method names also use camel case naming, for example: getUserInfo().

To call methods in the model, you need to instantiate the model in the controller, and then call the method through the instance object. For example, the following code demonstrates how to call methods in the model in the controller:

public function index()
{
    $userModel = new \app\model\UserModel();
    $userInfo = $userModel->getUserInfo(1);
    echo "姓名：".$userInfo['name']."<br>年龄：".$userInfo['age'];
}

3. Method calls in the view

The view is the place in the application responsible for displaying data. Views in ThinkPHP5 are located in the view directory under the app directory. The naming rule for views is camel case naming with .tpl as the suffix, for example: userList.tpl.

In the view, we can use built-in functions or custom functions to display data. For example, the following code demonstrates how to use the built-in function echo to output data in a view:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>用户列表</title>
</head>
<body>
    <table>
        <tr>
            <th>编号</th>
            <th>姓名</th>
            <th>年龄</th>
        </tr>
        <?php foreach($userList as $user) { ?>
        <tr>
            <td><?php echo $user[&#39;id&#39;]; ?></td>
            <td><?php echo $user[&#39;name&#39;]; ?></td>
            <td><?php echo $user[&#39;age&#39;]; ?></td>
        </tr>
        <?php } ?>
    </table>
</body>
</html>
