Advantages of PHP anti-shake technology and its application in actual projects

With the rapid development of the mobile Internet, users have increasing requirements for web applications. The higher. As users' operations in web applications increase frequently, an increase in front-end errors is inevitable. This results in continuous and repeated requests of the program, thereby occupying system resources and reducing the performance and response speed of the program. In order to solve this problem, I will introduce the advantages of PHP anti-shake technology and provide application examples in actual projects.

First of all, let us first understand what anti-shake technology is. Anti-shake technology means that the triggered event is only executed once within a period of time. When a user triggers the same event multiple times in a row in a web application, anti-shake technology will merge the events and execute the last event only once. In this way, you can avoid performing too many useless operations and improve the performance and response speed of the program.

The advantages of PHP anti-shake technology include:

  1. Reducing performance overhead: By merging multiple triggered events, redundant requests and responses can be reduced, thereby reducing system resource overhead.
  2. Improve user experience: When the user triggers the same event continuously, only the last event is executed, which can avoid unnecessary waiting time for the user and improve the user experience.
  3. Optimize program logic: Through anti-shake technology, some frequently triggered events can be processed and optimized to make the program logic clearer.

The following is a sample code that shows the application of PHP anti-shake technology in actual projects:

<?php
function debounce($callback, $wait = 1000) {
    $timeout = null;

    return function() use ($callback, $wait, &$timeout) {
        if ($timeout !== null) {
            clearTimeout($timeout);
        }

        $timeout = setTimeout($callback, $wait);
    };
}

// 在某个表单字段改变时触发事件
function handleInputChange() {
    // 处理表单字段改变的逻辑
}

// 使用防抖技术处理表单字段改变事件
$debouncedHandleInputChange = debounce('handleInputChange', 500);

// 监听表单字段改变事件
document.getElementById('inputField').addEventListener('input', $debouncedHandleInputChange);
?>
Copy after login

In the above example, we use the debounce function to wrap the handleInputChange function up so that anti-shake technology can be used to handle form field change events when they occur. The anti-shake function will only execute the handleInputChange function once within 500 milliseconds after the last event is triggered. This can reduce useless requests and responses and optimize program performance.

To sum up, PHP anti-shake technology has been widely used in actual projects. By using anti-shake technology, we can reduce the overhead of system resources, improve the user experience, and optimize the logic of the program. I hope this article can help you understand and apply PHP anti-shake technology.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
