How to implement the data caching and update strategy of Baidu Wenxin Yiyan interface in PHP development?
Baidu Wenxinyiyan is a very popular random sentence generation interface that can be used to decorate the website or display some interesting text.
However, when we use this interface, on the one hand, we must ensure the randomness of the generated sentences, and on the other hand, we must avoid frequent requests to the interface to save bandwidth and improve response speed. Therefore, during the development process, we can consider caching the interface data and implementing a regular update strategy.
1. Caching strategy
In PHP development, we can use caching to improve data access speed. For data from Baidu Wenxin Yiyan interface, we can choose to cache it in files, databases or memory.
- Cache to file
This is a simple and effective caching method. We can save the data returned by Baidu Wenxin Yiyan interface to a text file, and then read the data directly from the file when needed.
Sample code:
// 缓存文件路径 $cacheFile = 'cache/words.txt'; // 判断缓存文件是否存在 if (file_exists($cacheFile)) { // 判断缓存文件是否过期(可以根据具体需求设置缓存的有效期) if (time() - filemtime($cacheFile) < 3600) { // 从缓存文件中读取数据 $words = file_get_contents($cacheFile); } else { // 缓存文件过期,重新请求接口获取数据 $words = file_get_contents('https://api.xxxxx.com/word/api'); // 保存数据到缓存文件 file_put_contents($cacheFile, $words); } } else { // 缓存文件不存在,请求接口获取数据并保存到缓存文件 $words = file_get_contents('https://api.xxxxx.com/word/api'); file_put_contents($cacheFile, $words); } // 使用获取到的数据 echo $words;
- Cache to database
If a database has been used in your project, cache the data of Baidu Wenxinyiyan , you can save it to a database table.
Sample code:
// 数据库配置 $dbHost = 'localhost'; $dbUsername = 'root'; $dbPassword = '123456'; $dbName = 'mydatabase'; // 连接数据库 $conn = mysqli_connect($dbHost, $dbUsername, $dbPassword, $dbName); // 查询缓存数据 $result = mysqli_query($conn, 'SELECT * FROM cache_table WHERE id = 1'); if ($row = mysqli_fetch_assoc($result)) { // 判断缓存是否过期 if (time() - strtotime($row['update_time']) < 3600) { // 使用缓存数据 $words = $row['words']; } else { // 缓存过期,重新请求接口获取数据 $words = file_get_contents('https://api.xxxxx.com/word/api'); // 更新数据库缓存数据 mysqli_query($conn, 'UPDATE cache_table SET words = "'.$words.'", update_time = "'.date('Y-m-d H:i:s').'" WHERE id = 1'); } } else { // 缓存表不存在或者没有数据,请求接口获取数据并保存到数据库 $words = file_get_contents('https://api.xxxxx.com/word/api'); mysqli_query($conn, 'INSERT INTO cache_table (id, words, update_time) VALUES (1, "'.$words.'", "'.date('Y-m-d H:i:s').'")'); } // 使用获取到的数据 echo $words; // 关闭数据库连接 mysqli_close($conn);
2. Update strategy
In order to ensure the freshness of the data, we can develop an update strategy to regularly update the data in the cache. You can set the update frequency according to the actual situation, such as updating once every hour.
Sample code:
// 缓存策略 $cacheFile = 'cache/words.txt'; $updateInterval = 3600; // 更新间隔时间(单位:秒) // 判断缓存文件是否存在 if (file_exists($cacheFile)) { // 判断缓存文件是否过期 if (time() - filemtime($cacheFile) >= $updateInterval) { // 缓存文件过期,重新请求接口获取数据 $words = file_get_contents('https://api.xxxxx.com/word/api'); // 保存数据到缓存文件 file_put_contents($cacheFile, $words); } else { // 从缓存文件中读取数据 $words = file_get_contents($cacheFile); } } else { // 缓存文件不存在,请求接口获取数据并保存到缓存文件 $words = file_get_contents('https://api.xxxxx.com/word/api'); file_put_contents($cacheFile, $words); } // 使用获取到的数据 echo $words;
The above is the sample code to implement the data caching and update strategy of Baidu Wenxin Yiyan interface in PHP development. By rationally using caching and regular update strategies, you can improve website performance and user experience while ensuring the freshness of data.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
