Inspiration and design concepts for developing brain map function in PHP and Vue

Brain map is a graphical tool that displays information in a tree structure. It can help us organize , organize and understand complex concepts and thought patterns. The application scenarios of mind maps are very wide. From work and study to project management and knowledge organization, mind maps can play a huge role. In this article, we will discuss how to develop a simple mind mapping function using PHP and Vue, and share some design concepts and code examples.

Before we start, we first need to understand the basics of PHP and Vue. PHP is a commonly used server-side scripting language that can be used to process forms, generate dynamic pages, and perform database operations. Vue is a JavaScript framework for building user interfaces that allows us to build complex interactive interfaces in a declarative manner. The combination of these two technologies can help us develop a feature-rich and easy-to-maintain brain mapping function.

Before we start designing the brain map function, we first need to determine the data structure of the brain map. Brain maps usually consist of multiple nodes, each node contains a topic and some sub-nodes. In order to represent this hierarchical relationship, we can use a nested array to represent the tree structure. The sample data is as follows:

$tree = [
    [
        'id' => 1,
        'title' => '主题1',
        'children' => [
            [
                'id' => 2,
                'title' => '子主题1',
                'children' => []
            ],
            [
                'id' => 3,
                'title' => '子主题2',
                'children' => []
            ]
        ]
    ],
    [
        'id' => 4,
        'title' => '主题2',
        'children' => []
    ]
];

The above sample data represents a simple brain map in the form of a PHP array. Each node has a unique ID, a topic and an array of child nodes. Next, we will use PHP and Vue to display this mind map.

First, we need to create a PHP file to handle the loading and saving of data. Since this example is a simple static data, we can save the data in an array and output the data to the Vue component through PHP. The code is as follows:

<?php
header('Content-Type: application/json');

$tree = [
    ...
];

echo json_encode($tree);

Then, we need to create a Vue component to display the brain map. We can use Vue's component development method to build a reusable brain map component. The code is as follows:

<template>
  <div>
    <ul>
      <li v-for="node in tree" :key="node.id">
        {{ node.title }}
        <tree :tree="node.children" v-if="node.children.length > 0" />
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  name: 'Tree',
  props: {
    tree: {
      type: Array,
      required: true
    }
  }
}
</script>

In the Vue component, we use the v-for directive to traverse each node and display the child nodes recursively. In this way, we can realize an infinite level of brain mapping function.

Finally, we need to introduce PHP and Vue components into an HTML page and initialize the Vue application. The code is as follows:

<!DOCTYPE html>
<html>
<head>
  <title>脑图功能</title>
</head>
<body>
  <div id="app">
    <tree :tree="tree" />
  </div>

  <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
  <script>
    new Vue({
      el: '#app',
      data: {
        tree: []
      },
      mounted() {
        this.loadData();
      },
      methods: {
        loadData() {
          fetch('tree.php')
            .then(response => response.json())
            .then(data => {
              this.tree = data;
            });
        }
      }
    });
  </script>
</body>
</html>

In the above code, we use Vue’s mounted hook function to load data after the page is loaded.

Through the above code examples, we can see that it is very simple to develop brain mapping functions using PHP and Vue. By defining the data structure, creating PHP and Vue components, and introducing related resources, we can quickly build a fully functional mind mapping application. This combination of development methods using PHP and Vue can help us better separate the front-end and back-end code and improve the maintainability and scalability of the code.

In summary, the combination of PHP and Vue to develop the brain map function allows us to quickly build a brain map application that is fully functional, easy to maintain and expand. By defining data structures, creating PHP and Vue components, and introducing related resources, we can implement a simple and powerful mind mapping function. I hope that the inspiration and design concepts of this article can help readers better understand and apply PHP and Vue to develop mind mapping functions.
