Experiences and lessons learned from combining PHP and Vue to develop the brain map function

With the development of web applications, the brain map function plays an important role in information organization and knowledge management character of. In order to achieve this function, I chose to develop PHP and Vue together. Through this project, I gained a lot of insights and lessons, which I would like to share with you.

1. Build the environment

First, we need to prepare the PHP environment and Vue environment. PHP is a commonly used back-end language, mainly used for processing server-side data. Vue is a front-end framework that helps us build interactive user interfaces.

On the PHP side, we need to ensure that PHP and MySQL are installed. Integrated software packages such as XAMPP or WAMP can be used, which can install and configure the PHP environment with one click.

On the Vue side, we can use the scaffolding tool Vue CLI to quickly build a blank project. After installing Node.js, just run the following command:

npm install -g @vue/cli
vue create my-project

2. Data interaction

Data interaction between PHP and Vue is a very critical step. To implement the brain map function, we need to store and manage the user's brain map data on the back end, and display and edit it on the front end. This requires us to be able to perform data addition, deletion, modification and query operations.

On the PHP side, we can use extension libraries such as PDO or mysqli to connect to the MySQL database and perform corresponding SQL operations. The following is a simple example:

$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'password';
$dbname = 'mymindmap';

// 连接数据库
$conn = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbuser, $dbpass);

// 查询数据
$sql = "SELECT * FROM mindmap";
$result = $conn->query($sql);
$data = $result->fetchAll(PDO::FETCH_ASSOC);
echo json_encode($data);

On the Vue side, we can use the axios library to initiate an HTTP request and obtain data from the PHP interface. The following is a simple example:

<template>
  <div>
    <ul>
      <li v-for="item in mindmaps" :key="item.id">
        {{ item.title }}
      </li>
    </ul>
  </div>
</template>

<script>
import axios from 'axios';

export default {
  data() {
    return {
      mindmaps: [],
    };
  },
  
  mounted() {
    this.fetchMandmaps();
  },
  
  methods: {
    fetchMandmaps() {
      axios.get('/api/mindmaps')
        .then(response => {
          this.mindmaps = response.data;
        })
        .catch(error => {
          console.log(error);
        });
    },
  },
};
</script>

3. Component development

Using Vue for component development can improve the maintainability and reusability of the code. In the brain map function, we can regard the entire brain map as a component, and the nodes and connections as sub-components.

In Vue, you can use Vue CLI commands to create components:

vue component my-component

The created components will be automatically generated in the "src/components" directory of the project, and can be used when needed Components are referenced and used.

For example, we can create a "Mindmap" component and then reference it in the App component:

// Mindmap.vue
<template>
  <div>
    <!-- 脑图内容 -->
  </div>
</template>

<script>
export default {
  data() {
    return {
      // 脑图数据
    };
  },
};
</script>

// App.vue
<template>
  <div>
    <Mindmap />
  </div>
</template>

<script>
import Mindmap from './components/Mindmap.vue';

export default {
  components: {
    Mindmap,
  },
};
</script>

4. Lessons and Summary

During the development process, I also encountered Here are some questions and lessons learned. Some experiences are summarized below:

1. When performing data interaction between PHP and Vue, attention should be paid to the uniformity of the data format to facilitate data integration and processing.
2. The brain map function is highly complex, and the data processing and interaction logic are also relatively complex. Pay attention to the rationality of the code structure to avoid situations that are difficult to maintain.
3. When using Vue for component development, components must be divided reasonably to avoid components that are too large and complex, affecting performance and maintainability.
4. When you encounter problems during the development process, you must be good at finding relevant documents and resources, and communicate and discuss with the developer community to solve the problem as soon as possible.

Through the above project development, I have a deeper understanding of the brain map function developed by combining PHP and Vue. I hope the above experiences and lessons can inspire and help everyone when developing similar functions.
