PHPcms list page data import and export method sharing

PHPcms is a very popular content management system that users can use to create and manage pages, articles, images and other content on the website. In the process of using PHPcms, sometimes we need to import and export the data of the list page for backup, migration or sharing. This article will introduce how to use PHPcms to import and export list page data, and provide specific code examples.

Data export method

1. Use PHP to export data as a CSV file

First, we need to connect to the PHPcms database, query the data that needs to be exported, and then export the data Export to CSV file. The following is a simple sample code:

<?php

// 连接数据库
$conn = new mysqli('localhost', 'username', 'password', 'database');
if ($conn->connect_error) {
    die("连接数据库失败: " . $conn->connect_error);
}

// 查询需要导出的数据
$query = "SELECT * FROM cms_table";
$result = $conn->query($query);

// 创建CSV文件
$filename = "data.csv";
$fp = fopen($filename, 'w');

while ($row = $result->fetch_assoc()) {
    fputcsv($fp, $row);
}

fclose($fp);
echo "数据导出成功！";

Run this code to export the data in the database to a CSV file named "data.csv".

2. Use PHP to export data to JSON format

In addition to CSV files, we can also export data to JSON format for easy use in other systems. The following is a sample code exported to JSON:

<?php

// 连接数据库
$conn = new mysqli('localhost', 'username', 'password', 'database');
if ($conn->connect_error) {
    die("连接数据库失败: " . $conn->connect_error);
}

// 查询需要导出的数据
$query = "SELECT * FROM cms_table";
$result = $conn->query($query);

// 将数据转为JSON格式
$data = [];
while ($row = $result->fetch_assoc()) {
    $data[] = $row;
}

// 导出为JSON文件
$json = json_encode($data);
file_put_contents('data.json', $json);
echo "数据导出成功！";

Run this code to export the data in the database to a JSON file named "data.json".

Data import method

Next we will introduce how to import data from CSV files or JSON files into PHPcms.

1. Import data from CSV file

To import the data in the CSV file into PHPcms, we need to first read the CSV file and then insert it into the database. The following is a sample code:

<?php

// 连接数据库
$conn = new mysqli('localhost', 'username', 'password', 'database');
if ($conn->connect_error) {
    die("连接数据库失败: " . $conn->connect_error);
}

// 读取CSV文件
$filename = 'data.csv';
$file = fopen($filename, 'r');

while (($row = fgetcsv($file)) !== false) {
    $values = implode("','", $row);
    $query = "INSERT INTO cms_table VALUES ('$values')";
    $conn->query($query);
}

fclose($file);
echo "数据导入成功！";

2. Import data from JSON file

If the data is saved in a file in JSON format, we can use the following code to import it into PHPcms:

<?php

// 连接数据库
$conn = new mysqli('localhost', 'username', 'password', 'database');
if ($conn->connect_error) {
    die("连接数据库失败: " . $conn->connect_error);
}

// 读取JSON文件
$data = file_get_contents('data.json');
$data = json_decode($data, true);

// 插入数据
foreach ($data as $row) {
    $values = implode("','", $row);
    $query = "INSERT INTO cms_table VALUES ('$values')";
    $conn->query($query);
}

echo "数据导入成功！";

Through the above code example, we can import and export PHPcms list page data. Depending on the actual situation, we can adjust these codes as needed to meet different needs. Hope the above content can be helpful to you!
