Complementation and integration of PHP and Vue in brain map function development

The complementation and integration of PHP and Vue in the development of brain map functions

Overview:
Brain map is a graph that displays thinking relationships in a tree structure tools that can help us better organize and manage information. In the development process of brain map functions, PHP and Vue are two commonly used technology stacks. They can complement each other and integrate with each other to effectively realize the development of brain map functions.

1. PHP and back-end development
PHP is a scripting language executed on the server side, mainly used for web development. In the development of brain map functions, PHP can be responsible for tasks such as back-end server setup, data processing, and database operations. The following is an example PHP code for processing the addition, deletion, modification and query operations of nodes in the brain map:

<?php
// 获取脑图节点
function getNodes() {
  // 从数据库或其他数据源获取节点数据
  // 返回节点数据的JSON格式
}

// 添加脑图节点
function addNode($parentNode, $nodeContent) {
  // 将新节点插入到数据库或其他数据源中
  // 返回插入成功与否的状态
}

// 删除脑图节点
function deleteNode($nodeId) {
  // 从数据库或其他数据源中删除指定的节点
  // 返回删除成功与否的状态
}

// 更新脑图节点
function updateNode($nodeId, $newContent) {
  // 更新数据库或其他数据源中的节点内容
  // 返回更新成功与否的状态
}

// 处理前端请求
$action = $_GET['action'];
if ($action == 'get') {
  echo getNodes();
} else if ($action == 'add') {
  $parentNode = $_GET['parentNode'];
  $nodeContent = $_GET['nodeContent'];
  echo addNode($parentNode, $nodeContent);
} else if ($action == 'delete') {
  $nodeId = $_GET['nodeId'];
  echo deleteNode($nodeId);
} else if ($action == 'update') {
  $nodeId = $_GET['nodeId'];
  $newContent = $_GET['newContent'];
  echo updateNode($nodeId, $newContent);
}
?>

2. Vue and front-end development
Vue is a progressive JavaScript framework for building user interfaces. Mainly used for front-end development. In the development of brain map functions, Vue can be responsible for tasks such as front-end interface rendering and user interaction. The following is an example Vue code used to display mind map nodes and process user operations:

<template>
  <div id="mindmap">
    <div v-for="node in nodes" :key="node.id">
      {{ node.content }}
      <button @click="deleteNode(node.id)">删除</button>
      <input v-model="newContentMap[node.id]">
      <button @click="updateNode(node.id)">更新</button>
    </div>
    <input v-model="newNodeContent">
    <button @click="addNode()">添加</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      nodes: [],
      newContentMap: {},
      newNodeContent: ''
    };
  },
  methods: {
    getNodes() {
      // 发送请求获取脑图节点，并更新nodes数据
    },
    addNode() {
      // 发送请求添加脑图节点，并更新nodes数据
    },
    deleteNode(nodeId) {
      // 发送请求删除脑图节点，并更新nodes数据
    },
    updateNode(nodeId) {
      // 发送请求更新脑图节点的内容，并更新nodes数据
    }
  },
  mounted() {
    this.getNodes();
  }
};
</script>

3. Integration of PHP and Vue
In the development of mind map functions, PHP and Vue can Integrate with each other to achieve seamless connection between the front and back ends. The back-end data can be passed to the front-end Vue for display through the interface provided by PHP; at the same time, the front-end Vue can call the PHP interface by sending a request to add, delete, and modify the back-end data. The following is a sample code that integrates PHP and Vue:

<template>
  <div id="mindmap">
    <div v-for="node in nodes" :key="node.id">
      {{ node.content }}
      <button @click="deleteNode(node.id)">删除</button>
      <input v-model="newContentMap[node.id]">
      <button @click="updateNode(node.id)">更新</button>
    </div>
    <input v-model="newNodeContent">
    <button @click="addNode()">添加</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      nodes: [],
      newContentMap: {},
      newNodeContent: ''
    };
  },
  methods: {
    getNodes() {
      // 发送请求获取脑图节点，并更新nodes数据
      axios.get('/api/nodes?action=get')
        .then(response => {
          this.nodes = response.data;
        })
        .catch(error => {
          console.error(error);
        });
    },
    addNode() {
      // 发送请求添加脑图节点，并更新nodes数据
      axios.get('/api/nodes?action=add', {
        params: {
          parentNode: '',  // 父节点ID
          nodeContent: this.newNodeContent
        }
      })
        .then(response => {
          if (response.data) {
            this.getNodes();
          }
        })
        .catch(error => {
          console.error(error);
        });
    },
    deleteNode(nodeId) {
      // 发送请求删除脑图节点，并更新nodes数据
      axios.get('/api/nodes?action=delete', {
        params: {
          nodeId: nodeId
        }
      })
        .then(response => {
          if (response.data) {
            this.getNodes();
          }
        })
        .catch(error => {
          console.error(error);
        });
    },
    updateNode(nodeId) {
      // 发送请求更新脑图节点的内容，并更新nodes数据
      axios.get('/api/nodes?action=update', {
        params: {
          nodeId: nodeId,
          newContent: this.newContentMap[nodeId]
        }
      })
        .then(response => {
          if (response.data) {
            this.getNodes();
          }
        })
        .catch(error => {
          console.error(error);
        });
    }
  },
  mounted() {
    this.getNodes();
  }
};
</script>

IV. Summary
By integrating PHP and Vue, we can make full use of PHP's back-end processing capabilities and Vue's front-end interaction capabilities to make the brain Graph function development is more efficient and easier to maintain. PHP can be responsible for the operations of the back-end server and database, while Vue can be responsible for the rendering and user interaction of the front-end interface. The complementary and integrated development model of the two can help us better realize functional requirements and improve user experience and development efficiency.
