Analysis of the wonders of integrating PHP and Vue to develop the brain map function

Introduction:
With the rapid development of the Internet, brain map as a structured Thinking tools are widely used in the fields of information organization and knowledge sharing. This article will explore how to use PHP and Vue to integrate and develop brain map functions to achieve flexible and efficient information display and management.

1. Design ideas for brain map function
Brain map is a hierarchical graphic organization method, usually composed of nodes and connections. When designing the brain map function, the following aspects need to be considered:

1. Data structure: The data structure of nodes and connections should be easy to organize and manage, and support fast addition, deletion, modification and query operations.
2. Page interaction: The nodes of the brain map should support dragging, zooming, editing and other operations, and the connections between nodes should also support association and adjustment.
3. Data storage: The node and connection data of the brain map should be stored in the database and support persistence and read operations.

2. Use PHP to implement the back-end interface

1. Database design: First, design a suitable database table structure to store the node and connection data of the brain map. For example, you can create two tables, one table is used to store node data (fields such as id, text, parentId, x, y, etc.), and the other table is used to store connection data (fields such as id, fromNodeId, toNodeId, etc.).
2. Back-end interface: Use PHP to write the back-end interface, and realize the addition, deletion, modification and query operations of brain map nodes and connections through the interface. For example, you can use the GET method to obtain node and connection data, the POST method to add nodes, the PUT method to update nodes, the DELETE method to delete nodes, etc.

Code example:

// 获取节点数据接口
app.get('/nodes', (req, res) => {
  // 从数据库中查询节点数据
  const nodes = db.query("SELECT * FROM nodes");
  res.send(nodes);
});

// 添加节点数据接口
app.post('/nodes', (req, res) => {
  // 从请求中获取节点数据
  const newNode = req.body;
  // 将节点数据插入数据库
  db.query(`INSERT INTO nodes (text, parentId, x, y) VALUES ('${newNode.text}', ${newNode.parentId}, ${newNode.x}, ${newNode.y})`);
  res.send("Node added successfully");
});

// 更新节点数据接口
app.put('/nodes/:id', (req, res) => {
  const nodeId = req.params.id;
  // 从请求中获取节点数据
  const updatedNode = req.body;
  // 更新数据库中指定id的节点数据
  db.query(`UPDATE nodes SET text = '${updatedNode.text}', x = ${updatedNode.x}, y = ${updatedNode.y} WHERE id = ${nodeId}`);
  res.send("Node updated successfully");
});

// 删除节点数据接口
app.delete('/nodes/:id', (req, res) => {
  const nodeId = req.params.id;
  // 从数据库中删除指定id的节点数据
  db.query(`DELETE FROM nodes WHERE id = ${nodeId}`);
  res.send("Node deleted successfully");
});

3. Use Vue to achieve front-end interaction

1. Install Vue: First, you need to install Vue.js and add it to the HTML page Import the Vue.js library file into .
2. Create components: Use Vue’s component development idea to create Node components and Mindmap components. The Node component is used to present mind map nodes, and the Mindmap component is used to display mind maps and handle operations such as dragging, zooming in, and editing.
3. Data interaction: Use Vue's two-way data binding mechanism to bind the node data obtained from the back-end interface to the front-end component to achieve real-time updates of page data.

Code example:

// Node组件
Vue.component('node', {
  props: ['node'],
  template: `
    <div :style="{left: node.x + 'px', top: node.y + 'px'}" class="node">
      <input v-model="node.text" :disabled="!node.editable" />
    </div>
  `
});

// Mindmap组件
Vue.component('mindmap', {
  props: ['nodes'],
  template: `
    <div class="mindmap">
      <node v-for="node in nodes" :key="node.id" :node="node"></node>
    </div>
  `,
  mounted() {
    // 调用后端接口，获取节点数据并绑定到组件上
    fetch('/nodes')
      .then(response => response.json())
      .then(data => {
        this.nodes = data;
      });
  }
});

// 创建Vue实例
new Vue({
  el: '#app',
  template: `
    <div id="app">
      <mindmap></mindmap>
    </div>
  `
});

IV. Summary
Through the integrated development of PHP and Vue, we have successfully implemented a flexible and efficient brain map function. PHP provides a back-end interface for processing the addition, deletion, modification, and query operations of node and connection data, and storing the data in the database. As a front-end framework, Vue is responsible for displaying mind maps and handling user interaction. The combination of PHP and Vue provides powerful support for realizing the brain map function, and also brings us more possibilities in the development of other fields.
