Application case sharing and practical experience summary of PHP anti-shake technology

Introduction:
In our daily development work, we often encounter some situations that require response User event scenarios, such as automatic completion of the search box, monitoring window scrolling events, monitoring real-time input in the input box, etc. However, in some special scenarios, frequent triggering of user events will cause multiple repeated requests, which puts considerable pressure on the server. In order to solve this problem, we can use PHP's anti-shake technology to control the frequency of requests and improve user experience and server performance.

1. Principle of anti-shake technology
Anti-shake technology is relatively common in front-end development. Its principle is to delay the execution of the corresponding operation for a certain period of time when the user triggers an event. If the event is triggered again within the delay time, the timer will be reset and the timing will start again. The corresponding operation will not be performed until the timing ends. This can effectively prevent users from triggering events frequently resulting in repeated operations.

2. Sharing of application cases of anti-shake technology

1. Auto-completion of the search box
   During the user input process, we can use anti-shake technology to realize the search box completion Autocomplete function. When the user continues to input, we can set a certain delay time. If there is no new input within the delay time, a request will be sent for the search operation.

function debounceSearch($keyword) {
    // 延迟时间设为500毫秒
    usleep(500000);
    
    // 进行搜索操作
    // ...
}

2. Listening to window scrolling events
   When the user scrolls the page, we can use anti-shake technology to listen for scrolling events to reduce repeated triggering.

function debounceScroll() {
    // 延迟时间设为200毫秒
    usleep(200000);
    
    // 监听滚动事件
    // ...
}

3. Monitor real-time input in the input box
   When inputting content in the user input box, we can achieve the effect of real-time input through anti-shake technology. Only after the user stops inputting for a period of time, relevant operations are performed, such as verification of the input box content, character statistics, etc.

function debounceInput($input) {
    // 延迟时间设为300毫秒
    usleep(300000);
    
    // 进行输入处理
    // ...
}

3. Summary of practical experience

1. Reasonably set the delay time
   When using anti-shake technology, we need to set the delay time reasonably to achieve good user experience Experience and performance optimization. If the delay time is too long, the user event response will be slow, and if the delay time is too short, the anti-shake effect will be easily lost.
2. Reduce duplicate requests
   Through the application of anti-shake technology, we can effectively reduce the pressure of repeated requests on the server. When the user triggers events continuously, the request will be sent only if there is no new trigger within the delay time, which greatly reduces the number of unnecessary requests.
3. Pay attention to the actual needs of the business scenario
   In the process of applying anti-shake technology, we need to reasonably choose to use anti-shake technology based on the actual needs of the business scenario. It is not suitable for anti-shake scenarios. Using anti-shake technology will affect the user experience.

Summary:
Through the application of anti-shake technology, we can effectively control the frequency of requests and improve user experience and server performance. In actual development, we need to choose an appropriate delay time based on different business scenarios, and comprehensively consider the needs of user experience and server performance.

The application of anti-shake technology in PHP development is a very valuable technology. I hope the above cases and experience summaries can bring some inspiration and help to your development work.
