How to use caching strategies to reduce the memory footprint of PHP programs?

Which folder does the browser cache the video in? When we use the Internet browser every day, we often watch various online videos, such as watching music videos on YouTube or watching movies on Netflix. These videos will be cached by the browser during the loading process so that they can be loaded quickly when played again in the future. So the question is, in which folder are these cached videos actually stored? Different browsers store cached video folders in different locations. Below we will introduce several common browsers and their

DNS (DomainNameSystem) is a system used on the Internet to convert domain names into corresponding IP addresses. In Linux systems, DNS caching is a mechanism that stores the mapping relationship between domain names and IP addresses locally, which can increase the speed of domain name resolution and reduce the burden on the DNS server. DNS caching allows the system to quickly retrieve the IP address when subsequently accessing the same domain name without having to issue a query request to the DNS server each time, thereby improving network performance and efficiency. This article will discuss with you how to view and refresh the DNS cache on Linux, as well as related details and sample code. Importance of DNS Caching In Linux systems, DNS caching plays a key role. its existence

A Beginner's Guide to Guava Cache: Speed ​​Up Your Applications Guava Cache is a high-performance in-memory caching library that can significantly improve application performance. It provides a variety of caching strategies, including LRU (least recently used), LFU (least recently used), and TTL (time to live). 1. Install Guava cache and add the dependency of Guava cache library to your project. com.goog

Title: Caching mechanism and code examples of HTML files Introduction: When writing web pages, we often encounter browser cache problems. This article will introduce the caching mechanism of HTML files in detail and provide some specific code examples to help readers better understand and apply this mechanism. 1. Browser caching principle In the browser, whenever a web page is accessed, the browser will first check whether there is a copy of the web page in the cache. If there is, the web page content is obtained directly from the cache. This is the basic principle of browser caching. Benefits of browser caching mechanism

How to Export Browser Cache Videos With the rapid development of the Internet, videos have become an indispensable part of people's daily lives. When browsing the web, we often encounter video content that we want to save or share, but sometimes we cannot find the source of the video files because they may only exist in the browser's cache. So, how do you export videos from your browser cache? This article will introduce you to several common methods. First, we need to clarify a concept, namely browser cache. The browser cache is used by the browser to improve user experience.

PHPAPCu (replacement of php cache) is an opcode cache and data cache module that accelerates PHP applications. Understanding its advanced features is crucial to utilizing its full potential. 1. Batch operation: APCu provides a batch operation method that can process a large number of key-value pairs at the same time. This is useful for large-scale cache clearing or updates. //Get cache keys in batches $values=apcu_fetch(["key1","key2","key3"]); //Clear cache keys in batches apcu_delete(["key1","key2","key3"]);2 .Set cache expiration time: APCu allows you to set an expiration time for cache items so that they automatically expire after a specified time.

In PHP development, the caching mechanism improves performance by temporarily storing frequently accessed data in memory or disk, thereby reducing the number of database accesses. Cache types mainly include memory, file and database cache. Caching can be implemented in PHP using built-in functions or third-party libraries, such as cache_get() and Memcache. Common practical applications include caching database query results to optimize query performance and caching page output to speed up rendering. The caching mechanism effectively improves website response speed, enhances user experience and reduces server load.

There is a close interaction between the CPU (central processing unit), memory (random access memory), and cache, which together form a critical component of a computer system. The coordination between them ensures the normal operation and efficient performance of the computer. As the brain of the computer, the CPU is responsible for executing various instructions and data processing; the memory is used to temporarily store data and programs, providing fast read and write access speeds; and the cache plays a buffering role, speeding up data access speed and improving The computer's CPU is the core component of the computer and is responsible for executing various instructions, arithmetic operations, and logical operations. It is called the "brain" of the computer and plays an important role in processing data and performing tasks. Memory is an important storage device in a computer.
