How to implement caching of Baidu Wenxin Yiyan random sentences in PHP development?

Introduction:
Baidu Wenxin Yiyan is a very popular open source project that can provide various types of sentences, such as famous quotes, inspirational sentences, etc. In PHP development, we usually need to integrate these sentences into the website to provide them for users to read. However, since each request requires sending a request to Baidu Wenxin Yiyan API to obtain sentences, this will cause the load on the server to be too high and will also have a certain impact on the performance of the website. To alleviate these problems, we can use caching technology.

Cache life control:
In PHP development, we usually use cache to temporarily store some frequently accessed data to reduce the number of database queries and API requests. Baidu Wenxin Yiyan API is no exception. We can use caching technology to store the obtained sentences and set a reasonable cache life. For Baidu Wenxin Yiyan, its sentences are relatively stable and will not change much over a period of time, so we can set the cache life to a longer period of time, such as one day.

Cache processing example:
The following is a simple cache processing example, used to realize the cache storage and reading of Baidu Wenxin Yiyan sentences.

<?php

// 初始化缓存
$cache = new Memcached();
$cache->addServer('localhost', 11211);

// 缓存key
$cacheKey = 'baidu_wenxin_yiyan';

// 尝试从缓存读取数据
$data = $cache->get($cacheKey);

// 如果缓存不存在，则发送API请求获取数据
if (!$data) {
    $url = 'http://api.yiyan.baidu.com/recommend.json';
    $response = file_get_contents($url);
    $data = json_decode($response, true);

    // 将数据存入缓存，并设置过期时间为一天
    $cache->set($cacheKey, $data, 86400);
}

// 对获取到的数据进行处理
if ($data) {
    echo $data['motto'];
} else {
    echo '获取数据失败';
}

In the above code, we use Memcached as the cache server. You can also use other cache systems, such as Redis, etc. First we try to get the data from the cache. If the cache does not exist, we send an API request to get the data and store it in the cache. At the same time, we set the cache expiration time to one day. Finally, we output the obtained data, or prompt that the data acquisition failed.

Conclusion:
By implementing the cache processing of Baidu Wenxin Yiyan sentences, the load of each request can be reduced and the performance of the website can be improved. In PHP development, caching is a very important technology that can be used to optimize common operations such as database queries and API requests. In actual development, we can flexibly choose appropriate caching technologies and solutions based on specific needs and scenarios. I hope this article will help you implement caching in PHP development.
