PHP anti-shake technology: improve the smoothness and response speed of user operations

PHP anti-shake technology: To improve the smoothness and response speed of user operations, specific code examples are required

When developing web applications, the smoothness and response speed of user operations are required Response speed is critical. A common problem is that when users continuously click or frequently trigger a certain function button, the server will receive a large number of requests, thus affecting the performance and user experience of the web page. In order to solve this problem, we can use PHP anti-shake technology to limit the user's operating frequency.

What is anti-shake technology?
Anti-shake is a technology that limits the triggering frequency of events by delaying triggering. When an event is triggered, it will be checked within a certain time interval whether the event is triggered again. If the event is triggered again within the set time interval, the timing will be restarted; if the event is not triggered again within the set time interval, the corresponding operation will be performed.

Code example of using PHP to implement anti-shake function:

<?php
// 定义防抖时间间隔（单位：毫秒）
$debounceInterval = 500;

// 获取当前时间戳（毫秒）
function getCurrentTimestamp() 
{
    return round(microtime(true) * 1000);
}

// 初始化上次触发事件的时间戳
$lastTimestamp = getCurrentTimestamp();

// 用户操作触发的回调函数
function onUserAction() 
{
    global $lastTimestamp, $debounceInterval;

    // 获取当前时间戳
    $currentTimestamp = getCurrentTimestamp();

    // 判断是否在防抖时间间隔内
    if ($currentTimestamp - $lastTimestamp < $debounceInterval) {
        // 在防抖时间间隔内，不执行操作
        return;
    }

    // 执行相应的操作
    // ...

    // 更新上次触发事件的时间戳
    $lastTimestamp = $currentTimestamp;
}

// 测试防抖功能
// 模拟用户连续点击按钮
onUserAction();
sleep(0.1);
onUserAction();

In the above code example, we use a global variable $lastTimestamp to record the time of the last triggered event timestamp, and defines the debounce time interval $debounceInterval. When a user action triggers the callback function onUserAction, the current timestamp will first be obtained and compared with the timestamp of the last triggered event. If the time difference between the two is less than the anti-shake time interval, no operation is performed; otherwise, the corresponding operation is performed and the timestamp of the last triggered event is updated.

It is worth noting that the above code is just a simple example, and actual applications may involve more complex logic and business requirements. Developers need to make corresponding modifications and extensions based on specific application scenarios and needs.

Using PHP anti-shake technology can effectively improve the smoothness and response speed of user operations, avoid the server from receiving too many requests, thereby improving the performance and user experience of web applications. By setting an appropriate anti-shake time interval, the frequency of user operations can be controlled according to the actual situation, thereby achieving better interaction effects.

Summary:
This article introduces the concept and implementation principle of PHP anti-shake technology, and provides a simple code example. By using anti-shake technology, the frequency of user operations can be limited, the smoothness and response speed of user operations can be improved, thereby improving the performance and user experience of web applications. Developers can adjust the anti-shake time interval according to specific needs and application scenarios, and combine other technical means to further optimize web applications.
