How to use PHP and Vue to implement the data merging function

Introduction: Data merging is one of the very common requirements in daily development. Using PHP and Vue can easily implement the data merging function and provide a good user experience. This article will introduce how to use PHP backend and Vue frontend to implement the data merging function, and provide specific code examples.

1. Preparation
Before starting, you need to prepare the following tools and environment:

Server environment: Install necessary server environments such as PHP and MySQL.
Development tools: You can use any development tool, such as Visual Studio Code, Sublime Text, etc.
Vue.js: Make sure Vue.js has been installed. You can introduce Vue.js through npm or CDN.

2. Back-end interface implementation

Create database table
First, you need to create two tables in the database: Table A and Table B. These two tables respectively store the data items that need to be merged.

The structure of table A is as follows:

CREATE TABLE tableA (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(100),
  age INT
);

The structure of table B is as follows:

CREATE TABLE tableB (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(100),
  gender VARCHAR(10)
);

Create PHP interface
Next, create a PHP Interface, used to obtain the data of table A and table B, and return the data after merging the two tables.

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

// 连接数据库
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "database_name";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 获取表A和表B的数据
$aData = array();
$sql = "SELECT * FROM tableA";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $aData[] = $row;
    }
}

$bData = array();
$sql = "SELECT * FROM tableB";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $bData[] = $row;
    }
}

// 合并表A和表B的数据
$mergedData = array_merge($aData, $bData);

// 返回合并后的数据
echo json_encode($mergedData);

$conn->close();
?>

3. Front-end page implementation

Create Vue instance
Use Vue to manage data and display data in HTML pages. First, create a Vue instance and define data and methods.

<!DOCTYPE html>
<html>
<head>
    <title>数据合并功能示例</title>
    <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
    <div id="app">
        <ul>
            <li v-for="item in mergedData">{{ item.name }}</li>
        </ul>
    </div>

    <script>
        new Vue({
            el: '#app',
            data: {
                mergedData: []
            },
            mounted: function() {
                this.fetchData();
            },
            methods: {
                fetchData: function() {
                    // 调用后端接口获取数据
                    fetch('api.php')
                        .then(response => response.json())
                        .then(data => {
                            this.mergedData = data;
                        });
                }
            }
        })
    </script>
</body>
</html>

4. Test

Start the server
Place the above PHP files and HTML files on the server to ensure that the server has been started.
Open the page in the browser
Enter the server address in the browser to open the front-end page. The page will automatically call the backend interface to obtain data and display the merged data on the page.

Conclusion:
This article introduces how to use PHP and Vue to implement the data merging function, and provides specific code examples. By combining the PHP backend and Vue frontend, we can easily merge data and present users with a good user experience. I hope this article will be helpful to developers who are new to data merging.
