PHP anti-shake technology implementation plan and its application effect in the project

With the rapid development of the Internet, user interaction in Web applications has become more and more complex. the more often. Some user operations on the page may trigger read and write operations in the background database, and the frequent occurrence of these operations may put pressure on the system. Therefore, in order to ensure the stability and response speed of the system, we need to control user operations to prevent frequent triggering of background operations. Here we introduce an anti-shake technology implemented in PHP and its application effect in the project.

1. Implementation plan of anti-shake technology

Anti-shake technology (Debounce) is a technology commonly used in front-end development to solve the problem of frequent execution of continuously triggered events. question. In PHP, we can achieve similar effects by utilizing caches and timers.

First of all, we need to introduce a caching mechanism. PHP itself provides a variety of caching solutions, such as Memcached, Redis, etc. We can use these caching solutions to store user operation records. Whenever a user triggers an action, we record it and set a reasonable expiration time. Within a certain period of time, if the user triggers the same operation multiple times, we can decide whether to perform subsequent operations by judging whether the same record exists in the cache.

Then, we also need to use the timer mechanism. PHP itself also provides a variety of timer solutions, such as cron tasks, swoole, etc. We can set a timer to execute a certain piece of code regularly within a certain period of time. In anti-shake technology, we can use timers to determine the expiration time of user operation records and delete them from the cache.

Taken together, we can implement anti-shake technology in PHP through the caching mechanism and timer mechanism. The specific implementation method is as follows:

// 文件：debounce.php

// 引入缓存组件，此处以 Redis 为例
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

// 用户操作唯一标识，可根据实际情况进行生成，此处以前缀加时间戳为例
$identifier = 'user_action_' . time();

// 判断缓存中是否存在相同的记录
if ($redis->exists($identifier)) {
    // 存在相同的记录，则不执行后续操作
    echo '请勿频繁操作';
    exit;
} else {
    // 不存在相同的记录，则将其记录下来，并设置过期时间
    $redis->setex($identifier, 10, '1');  // 10 秒后过期
}

// 真正执行操作的代码
// ...

// 删除缓存中的记录
$redis->del($identifier);

// 接下来是其他后续操作
// ...

2. The application effect of anti-shake technology in the project

The application range of anti-shake technology in the project is very wide. For example, in an e-commerce website, users may frequently click the "Add to Shopping Cart" button, and each click will trigger read and write operations in the background database. If not controlled, such frequent operations may cause considerable burden on the database. By using anti-shake technology, we can control the user to only perform one operation within a period of time, thereby reducing the pressure on the background database. Similar scenarios include user search operations, comment operations, etc.

The application effect of anti-shake technology in the project is remarkable. By controlling user operations, unnecessary resource consumption can be reduced and the stability and response speed of the system can be improved. At the same time, reasonable restrictions on user operations can also improve user experience and avoid unnecessary troubles caused by frequent operations.

To sum up, PHP anti-shake technology realizes the control of user operations by utilizing the characteristics of cache and timer. By rationally applying anti-shake technology, we can effectively reduce resource consumption in the project and improve the stability and response speed of the system. At the same time, anti-shake technology can also improve the user experience and avoid user troubles caused by frequent operations. In actual projects, we can flexibly use anti-shake technology according to specific needs and scenarios to achieve better results.
