Analysis of the advantages of brain map function development integrating PHP and Vue technology

The brain map function is a very common and practical function that can help users organize and display Complex mind maps. During the development process, the integration of these two technologies, PHP and Vue, can bring many advantages. This article will introduce some advantages of integrating PHP and Vue technology to develop brain mapping functions, and provide corresponding code examples.

1. Separation of front-end and back-end: Use Vue to implement front-end functions, and PHP as the back-end to provide interfaces to achieve separation of front-end and back-end. This separated development model has the advantages of high flexibility and maintainability. The following is a simple example:

Vue code part:

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

<script>
export default {
  data() {
    return {
      items: []
    }
  },
  mounted() {
    this.fetchItems()
  },
  methods: {
    fetchItems() {
      // 调用后端接口获取数据
      axios.get('/api/items')
        .then(response => {
          this.items = response.data
        })
        .catch(error => {
          console.log(error)
        })
    }
  }
}
</script>

PHP code part:

<?php
// 在这里连接数据库

$items = [];

// 从数据库中获取数据
$result = mysqli_query($conn, "SELECT * FROM items");
while ($row = mysqli_fetch_assoc($result)) {
    $items[] = $row;
}

// 返回数据
header('Content-Type: application/json');
echo json_encode($items);
?>

2. Data interaction: PHP as the backend, you can Conveniently process the data passed by the front end and perform corresponding business logic processing. The following is an example:

Vue code part:

<template>
  <div>
    <input v-model="itemName">
    <button @click="addItem">添加</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      itemName: ''
    }
  },
  methods: {
    addItem() {
      // 调用后端接口添加数据
      axios.post('/api/addItem', { name: this.itemName })
        .then(response => {
          // 添加成功后刷新页面
          location.reload()
        })
        .catch(error => {
          console.log(error)
        })
    }
  }
}
</script>

PHP code part:

<?php
// 在这里连接数据库

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $name = $_POST['name'];

    // 处理数据并添加到数据库中
    mysqli_query($conn, "INSERT INTO items (name) VALUES ('$name')");

    // 返回成功消息
    header('Content-Type: application/json');
    echo json_encode(['message' => '添加成功']);
}
?>

3. Efficient real-time updates: using Vue’s reactive mechanism And the real-time data interface provided by PHP can realize real-time update function, for example, it can display other users' modifications to the brain map in real time. The following is an example:

Vue code part:

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

<script>
export default {
  data() {
    return {
      items: []
    }
  },
  mounted() {
    // 调用后端接口获取数据
    this.fetchItems()

    // 定时更新数据
    setInterval(() => {
      this.fetchItems()
    }, 1000)
  },
  methods: {
    fetchItems() {
      axios.get('/api/items')
        .then(response => {
          this.items = response.data
        })
        .catch(error => {
          console.log(error)
        })
    }
  }
}
</script>

PHP code part:

<?php
// 在这里连接数据库

if ($_SERVER['REQUEST_METHOD'] === 'GET') {
    $items = [];

    // 从数据库中获取数据
    $result = mysqli_query($conn, "SELECT * FROM items");
    while ($row = mysqli_fetch_assoc($result)) {
        $items[] = $row;
    }

    // 返回数据
    header('Content-Type: application/json');
    echo json_encode($items);
}
?>

Through the above example, it can be seen that the integration of PHP and Vue technology is There are many advantages in brain map function development, including front-end and back-end separation, data interaction and real-time updates. This development model can make development more flexible and efficient. In actual development, developers can choose appropriate technologies according to specific needs and scenarios to realize the development of brain map functions.
