How to use PHP and Vue to implement data replication function

In modern web application development, data replication is a common requirement. For example, when the user needs to copy data from one table to another table, or needs to copy the content of one article to another article. This article will introduce how to use PHP and Vue to implement such data copy function, and provide specific code examples.

1. Preparation
   Before you start, make sure you have set up the development environment for PHP and Vue. If you haven't already, please install PHP and Vue first and make sure they work properly.
2. Create database tables
   First, we need to create two tables in the database to store original data and copied data respectively. The following is a simple example:

CREATE TABLE original_data (
    id INT PRIMARY KEY AUTO_INCREMENT,
    content TEXT
);

CREATE TABLE copied_data (
    id INT PRIMARY KEY AUTO_INCREMENT,
    content TEXT
);

3. Create a backend API
   Next, we need to create a backend API to handle the logic of data replication. In PHP, we can use PDO extension to connect to the database and execute SQL queries. The following is a simple example:

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

$pdo = new PDO('mysql:host=localhost;dbname=your_database_name;charset=utf8', 'your_username', 'your_password');

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

    $insertSql = "INSERT INTO copied_data (content) VALUES (:content)";
    $statement = $pdo->prepare($insertSql);
    $statement->bindParam(':content', $content);
    $statement->execute();

    $result = ['success' => true];
} else {
    $result = ['success' => false, 'message' => 'Invalid request method'];
}

echo json_encode($result);
?>

4. Creating the front-end interface
   Now we can start creating the front-end interface. In Vue, we can use the axios library to send HTTP requests. The following is a simple example:

<template>
  <div>
    <textarea v-model="originalData"></textarea>
    <button @click="copyData">复制</button>
  </div>
</template>

<script>
import axios from 'axios';

export default {
  data() {
    return {
      originalData: '',
    };
  },
  methods: {
    copyData() {
      axios.post('/api/copy_data.php', { content: this.originalData })
        .then(response => {
          if (response.data.success) {
            alert('复制成功！');
          } else {
            alert('复制失败，请重试。');
          }
        })
        .catch(error => {
          console.error(error);
          alert('服务器错误，请稍后再试。');
        });
    },
  },
};
</script>

In the above code, we use Vue's two-way binding to process what the user enters in the text box. When the user clicks the copy button, we send a POST request to the backend API and use the user input as a parameter of the request. Based on the results returned by the backend, we will pop up a prompt box to inform the user whether the copy is successful.

5. Connect the front and back ends
   Finally, we need to connect the front and back ends. In the Vue entry file, add the following code:

import Vue from 'vue';
import App from './App.vue';

Vue.config.productionTip = false;

new Vue({
  render: h => h(App),
}).$mount('#app');

Now, we have completed all the steps to implement the data copy function using PHP and Vue. When you run the application, you will be able to enter content in the text box and copy it to another form by clicking the copy button. Is not it simple? Hurry up and give it a try!
