In-depth study of the key code implementation of PHP and Vue in the brain map function

Abstract: This article will deeply explore the key codes of PHP and Vue in the implementation of the brain map function accomplish. Brain mapping is a graphical tool commonly used to display thinking structures and relationships. It is widely used in fields such as project planning, knowledge management, and information organization. By learning the relevant knowledge of PHP and Vue, we can implement a simple yet powerful brain mapping application.

Understand PHP

PHP is a commonly used server-side scripting language. It is easy to learn, highly scalable, and widely supported, making it an ideal choice for building dynamic websites and web applications. The following is a sample code that uses PHP to implement the mind map function:

class MindMap {
    private $nodes = array();
    
    public function addNode($id, $text) {
        $node = array('id' => $id, 'text' => $text);
        array_push($this->nodes, $node);
    }
    
    public function toJson() {
        return json_encode($this->nodes);
    }
}

$mindMap = new MindMap();
$mindMap->addNode(1, 'Root');
$mindMap->addNode(2, 'Node 1');
$mindMap->addNode(3, 'Node 2');
echo $mindMap->toJson();

In the above code, we define a class named MindMap to represent the mind map. We can add nodes using the addNode() method and convert the brain map into a JSON formatted string using the toJson() method. Finally, we output the JSON representation of the brain map through the echo statement.

Learn Vue

Vue is a popular JavaScript framework for building interactive web interfaces. It is easy to learn, easy to use, flexible and efficient, and is widely used in front-end development. The following is a sample code that uses Vue to implement the brain map function:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
    <div id="app">
        <ul>
            <li v-for="node in nodes" :key="node.id">{{ node.text }}</li>
        </ul>
    </div>

    <script>
        new Vue({
            el: '#app',
            data: {
                nodes: [
                    { id: 1, text: 'Root' },
                    { id: 2, text: 'Node 1' },
                    { id: 3, text: 'Node 2' }
                ]
            }
        });
    </script>
</body>
</html>

In the above code, we use the Vue framework to create a Vue instance named app and initialize a set of node data in the data attribute. . Through the v-for directive, we can dynamically traverse node data and render it on the page.

Combining PHP and Vue to realize the brain map function

To realize the brain map function, we can use PHP and Vue together. The specific steps are as follows:

1) In PHP, define a MindMap class to provide methods for adding nodes and converting to JSON format. Refer to the above PHP code.

2) In PHP, use JSON formatted strings to store the brain map data and pass it to the front end.

$mindMap = new MindMap();
$mindMap->addNode(1, 'Root');
$mindMap->addNode(2, 'Node 1');
$mindMap->addNode(3, 'Node 2');
$data = $mindMap->toJson();

echo "<script>var mindMapData = $data;</script>";

3) In Vue, create a Vue instance named app and use the brain map data passed from PHP in the data attribute.

<div id="app">
    <ul>
        <li v-for="node in nodes" :key="node.id">{{ node.text }}</li>
    </ul>
</div>

<script>
    new Vue({
        el: '#app',
        data: {
           nodes: mindMapData
        }
    });
</script>

Through the above steps, we can implement a simple brain map application. In PHP, we define the data structure representing the brain map and provide related methods. In Vue, we use the mind map data passed from PHP to dynamically render the page.

Conclusion: By in-depth study of the key code implementations of PHP and Vue, we can implement a simple and powerful mind mapping application. PHP provides the ability to process data, while Vue provides dynamic rendering and interaction functions. By combining these two technologies, we can easily build satisfying brain mapping applications.
