Using PHP development to implement regular cleaning and garbage collection of Baidu Wenxin Yiyan API interface

In the process of developing web applications, we often rely on some external Services or APIs to provide some specific functions. Baidu Wenxin Yiyan API is such a very popular service, which can provide various types of inspirational, philosophical, emotional and other sentences.

However, due to a large number of users using this API to obtain statements, the amount of data in the database will gradually increase, which requires us to perform regular cleaning and garbage collection to reduce the burden on the database and improve program performance.

This article will introduce how to use PHP to develop a regular cleaning and garbage collection script in order to effectively manage the data of Baidu Wenxin Yiyan API.

First, we need to create a PHP script to connect to the database and implement cleaning and garbage collection functions. The specific implementation is as follows:

<?php
// 数据库连接配置
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

// 创建数据库连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接数据库失败: " . $conn->connect_error);
}

// 定义清理和垃圾回收的函数
function cleanAndCollectGarbage($conn) {
    // 设置定期清理的时间间隔（单位：小时）
    $cleanupInterval = 24;

    // 获取当前时间
    $currentTime = time();

    // 计算清理的截止时间
    $cleanupTime = $currentTime - ($cleanupInterval * 3600);

    // 构建SQL查询语句
    $sql = "DELETE FROM quotes WHERE created_at < $cleanupTime";

    // 执行SQL查询
    if ($conn->query($sql) === TRUE) {
        echo "清理完成！";
    } else {
        echo "清理过程中发生错误：" . $conn->error;
    }
}

// 调用清理和垃圾回收函数
cleanAndCollectGarbage($conn);

// 关闭数据库连接
$conn->close();
?>

In the above code, we first define a function cleanAndCollectGarbage. This function will clean the data in the database according to the specified time interval. In the function, we first set the cleaning interval to 24 hours, and then calculate the cleaning deadline. Next, we built a SQL query to delete data created before the deadline. Finally, we output corresponding prompt information based on the execution results.

After saving the above code as a PHP script, we can use cron (Linux) or scheduled tasks (Windows) to execute this script regularly to achieve automatic cleaning and garbage collection. For example, we can save the script as a clean.php file and set up regular execution in the following way:

# 每天凌晨3点执行清理脚本
0 3 * * * php /path/to/clean.php >/dev/null 2>&1

With the above settings, the cleaning script will be automatically executed at 3 am every day, Regularly clean the data of Baidu Wenxinyiyan API.

It should be noted that in order to successfully connect to the database, you need to configure $servername, $username, $password## according to the actual situation. # and $dbname The values ​​of these four variables.

To summarize, this article introduces how to use PHP to develop a regular cleaning and garbage collection script to effectively manage the data of Baidu Wenxin Yiyan API. Through regular cleaning and garbage collection, we can reduce the burden on the database, improve program performance, and provide better services.
