Application of the collaborative development model of PHP and Vue in the brain map function

Introduction:
With the increasing popularity of Web applications, mind maps have become a A tool widely used in fields such as project management, knowledge organization, and mind mapping. In modern web development, PHP and Vue are two commonly used technology stacks. This article will explore the application of the collaborative development model of PHP and Vue in the brain map function, and illustrate it through code examples.

1. PHP back-end development
PHP is a scripting language widely used in Web development. It has the advantages of being easy to learn, rapid development, and extensive ecological environment. In the brain map function, PHP is mainly responsible for processing back-end logic, such as data addition, deletion, modification and query, user authentication and permission control, etc.

The following is a simple PHP code example that implements an interface for obtaining brain map content through GET requests:

<?php
// 初始化数据库连接
$con = mysqli_connect("localhost","username","password","database");

// 获取脑图内容的函数
function getMindMap($mindMapId) {
    global $con;
    $sql = "SELECT content FROM mind_map WHERE id = ?";
    $stmt = mysqli_prepare($con, $sql);
    mysqli_stmt_bind_param($stmt, "i", $mindMapId);
    mysqli_stmt_execute($stmt);
    mysqli_stmt_bind_result($stmt, $content);
    mysqli_stmt_fetch($stmt);
    mysqli_stmt_close($stmt);
    return $content;
}

// 处理GET请求
if ($_SERVER["REQUEST_METHOD"] == "GET") {
    $mindMapId = $_GET["id"];
    $content = getMindMap($mindMapId);
    echo json_encode(array("content" => $content));
}
?>

In the above code, we first configure the database connection parameters and define A function getMindMap is created to obtain the content of the mind map. Then, in the logic of processing the GET request, we obtain the ID of the mind map from the query parameters, and call the getMindMap function to obtain the content of the brain map, and return it to the front end in JSON format.

2. Vue front-end development
Vue is a popular JavaScript framework that is simple and easy to use, responsive data binding and component-based development. In the brain map function, Vue is mainly used for front-end page rendering, user interaction and data display.

The following is a simple Vue code example, which implements a page that obtains and displays a brain map through a GET request:

<!DOCTYPE html>
<html>
<head>
    <title>Mind Map Viewer</title>
    <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
    <div id="app">
        <div>{{ content }}</div>
    </div>
    <script>
        new Vue({
            el: '#app',
            data: {
                content: ''
            },
            mounted() {
                this.fetchMindMap();
            },
            methods: {
                fetchMindMap() {
                    const url = 'api.php?id=1'; // 假设请求id为1的脑图
                    fetch(url)
                        .then(response => response.json())
                        .then(data => {
                            this.content = data.content;
                        })
                        .catch(error => console.error(error));
                }
            }
        });
    </script>
</body>
</html>

In the above code, we use Vue to create a root component and A variable content is defined in its data to store the content of the brain map. In the mounted life cycle hook function, we call the fetchMindMap method to obtain the mind map content through a GET request and assign it to the content variable. Then, we use Vue’s template syntax {{ content }} to display the brain map content.

Conclusion:
Through the above code examples, we can see the application of the collaborative development model of PHP and Vue in the brain map function. PHP is responsible for processing the back-end logic and providing an API interface to obtain the brain map content. Vue is responsible for the rendering and data display of the front-end page, obtaining the brain map content through asynchronous requests and displaying it on the page. This collaborative development model allows the back-end and front-end to be developed independently, with a good division of labor and responsibilities, which improves development efficiency and code maintainability.

However, this is just a simple example and cannot fully demonstrate all the advantages of the collaborative development model of PHP and Vue in the mind mapping function. In actual development, more requirements and complex business logic need to be taken into consideration. Therefore, the development team needs to select appropriate technologies and development models based on the needs of specific projects, and continuously optimize and improve them to improve development efficiency and user experience.
