Use PhpFastCache to optimize the data loading speed of front-end and back-end separated projects

In projects with front-end and back-end separation, the front end usually initiates a request to the back end to obtain data. Due to reasons such as network latency and server load, data loading speed may become slow, affecting the user experience. To solve this problem, we can use PhpFastCache to optimize data loading speed.

PhpFastCache is an efficient caching library that can cache data into files, memory or databases, thereby reducing the number of database queries or remote requests and increasing the speed of data acquisition.

Below we use an example to demonstrate how to use PhpFastCache to optimize the data loading speed of front-end and back-end separation projects.

Suppose we have a product list page. The front end needs to obtain product data from the back end and display it on the page. Normally, the front end initiates a request to the back end, and the back end queries the database to obtain product data, and then returns it to the front end. This process may take a long time.

First, we need to install PhpFastCache in the backend project. It can be installed through composer and run the following command:

composer require patricklucas/phpfastcache

After the installation is complete, we can use PhpFastCache in the backend interface to cache product data.

// 引入PhpFastCache
use PhpFastCacheCorePoolExtendedCacheItemPoolInterface;
use PhpFastCacheCacheManager;

// 初始化PhpFastCache
$cache = CacheManager::getInstance('files');

// 设置缓存键值
$cacheKey = 'product_data';

// 从缓存中获取数据
$productData = $cache->getItem($cacheKey);

// 如果缓存未命中，则从数据库中获取数据
if (!$productData->isHit()) {
    // 查询数据库获取产品数据
    $productData = getProductDataFromDatabase();

    // 将数据设置到缓存中，缓存时间为一小时
    $productData->expiresAfter(3600);
    $cache->save($productData);

    // 将产品数据返回给前端
    return $productData->get();
}

// 如果缓存命中，则直接返回缓存的数据给前端
return $productData->get();

In the above code, we first introduced the PhpFastCache library, and then initialized a cache instance. Next, we define a cache key value and obtain data from the cache through the getItem() method.

If the cache misses, it means there is no corresponding data in the cache. We need to get the product data from the database and set it into the cache. Here, we set an expiration time for product data to ensure data synchronization.

If the cache hits, the cached data will be returned directly to the front end, thereby accelerating the data loading process.

By using PhpFastCache, we can greatly reduce the number of database queries or remote requests, thereby increasing the speed of data acquisition. For some data that does not change frequently, we can cache the data for a longer period of time to further improve performance.

Summary:

In front-end and back-end separation projects, data loading speed is an important consideration. By using caching libraries like PhpFastCache, we can cache data, thereby increasing the speed of data acquisition and optimizing user experience. In practical applications, we can determine the data caching strategy based on specific business scenarios to achieve the best performance optimization effect.
