Baidu Wenxin Yiyan (Baidu Heart Words) is a random quote generator that can generate famous quotes and popular online phrases. Each generated sentence is full of insight and inspiration. This tool can be used as an emotional text rendering, triggering emotional resonance among users, making it highly valuable for use in various applications.
In practice, Baidu Wenxin Yiyan generates quotes by randomly selecting a certain number of words from a pre-stored large text material library and combining them into a meaningful quote. The program can generate more poetic sentences by adjusting the random weights to filter out emotional and deep words. For example:
$content = [
'Virtue and talent are like comets, talent and wisdom are like the spring sun.',
'There is no best bird song, as long as you are willing to listen, it is the most beautiful sound.',
'True friendship is not about distance, nor the frequency of contact.',
];
$rand_keys = array_rand($content, 1);
echo $content[$rand_keys]; // Get a random quote
By randomly selecting a quote from the $content array, you can generate a random sentence from Baidu Wenxin Yiyan.
In PHP development, caching technology is commonly used to improve website response speed. Caching can reduce the number of database accesses, thus enhancing website performance and reducing network latency, ultimately optimizing application response time.
While generating random sentences is simple, if the generation process takes too long, it can negatively affect the overall application performance. When the number of client devices increases or if there is heavy access, the server may become unstable due to the excessive time spent generating random sentences, affecting system performance and scalability.
Each random sentence generation requires some computational resources. In high-concurrency scenarios, the repetitive creation and destruction of processes can significantly slow down response times, so optimizing the random generation process is crucial.
Memcached is an open-source distributed caching system that helps reduce database load and accelerate dynamic web applications. Since the cached data is stored in memory, it is extremely fast and highly scalable.
To simplify caching operations, you can encapsulate the write and read processes into functions, making it easier for developers to use. For example, the following code demonstrates how to write a random sentence into Memcached cache:
/**
* Write to cache
*
* @param string $key Cache key
* @param string $data Data to cache
* @param int $time Cache expiration time
* @return bool
*/
function setCache(string $key, string $data, int $time = 3600): bool {
$memcache = new Memcached();
$memcache->addServer('127.0.0.1', 11211);
return $memcache->set($key, $data, $time);
}
This function binds the data to the specified key and stores it in the Memcached cache, setting the cache expiration time. Using this function, the caching process becomes more efficient.
Similar to writing to the cache, you can create a function to read from the cache. Below is the code to read data from the Memcached cache:
/**
* Read from cache
*
* @param string $key Cache key
* @return string
*/
function getCache(string $key): string {
$memcache = new Memcached();
$memcache->addServer('127.0.0.1', 11211);
return $memcache->get($key);
}
With this function, you can quickly retrieve data from the cache. If the data is not present in the cache, you can fetch it from the Wenxin random sentence library and store it in the cache.
Here’s how you can combine caching and random sentence generation to optimize the website performance:
$key = 'random_sentence';
$data = getCache($key);
if (!$data) {
// Data not found in cache, generate new quote
$data = getRandomSentence();
setCache($key, $data);
}
echo $data;
The code checks if the corresponding data exists in the cache. If not, it fetches a new random sentence from the Wenxin library, stores it in the cache, and then returns the data. This approach speeds up the process and improves the response on client devices.
In PHP development, caching technology is an effective way to improve application performance. This article demonstrated how to implement caching for Baidu Wenxin Yiyan random sentences using the Memcached tool and how to encapsulate caching operations into functions for easier integration. Caching significantly improves system performance and optimizes the user experience.
