Methods for implementing cache acceleration in PHP and MySQL combined with Redis
Article Introduction：Redis is needed to speed up the combination of PHP and MySQL, because Redis can significantly increase data access speed and reduce database query burden. Specific methods include: 1. Cache MySQL query results into Redis to reduce the number of direct queries; 2. Use publish-subscribe mode or transaction to ensure cache consistency; 3. Prevent cache penetration through Bloom filters; 4. Set different expiration times or use distributed locks to avoid cache avalanches; 5. Implement hierarchical cache, data warm-up and dynamic adjustment strategies to further optimize performance.

Speeding up Existing Apps with a Redis Cache
Article Introduction：Redis accelerates existing applications: cache queries to reduce server load
Core points:
Redis effectively accelerates existing applications by caching query results, thereby reducing server stress. It stores query results for a specified time (for example, 24 hours), and then reuses these results, significantly improving application speed.
The installation of Redis can be done through the operating system package manager or manually. The installation process includes avoiding common warnings and ensuring that Redis starts automatically after the server restarts.
The Predis library works with Redis to provide a memory cache layer for applications. This process involves checking whether the results of the current query exist in the cache, if not, get the result and transfer it

Laravel Cache Optimization: Redis and Memcached Configuration Guide
Article Introduction：In Laravel, Redis and Memcached can be used to optimize caching policies. 1) To configure Redis or Memcached, you need to set connection parameters in the .env file. 2) Redis supports a variety of data structures and persistence, suitable for complex scenarios and scenarios with high risk of data loss; Memcached is suitable for quick access to simple data. 3) Use Cachefacade to perform unified cache operations, and the underlying layer will automatically select the configured cache backend.

Application of Redis Bloom Filter in Cache Penetration Protection
Article Introduction：Use the Bloom filter to protect cache penetration because it can quickly determine whether an element may exist, intercept non-existent requests, and protect the database. The Redis Bloom filter efficiently judges the existence of elements through low memory usage, successfully intercepts invalid requests, and reduces database pressure. Despite the misjudgment rate, such misjudgment is acceptable in cache penetration protection.

How to solve the problem of redis cache breakdown
Article Introduction：Redis cache breakdown solution: Add a mutex: acquire a distributed lock before querying the database to prevent concurrent queries. Asynchronous update cache: Put cache update operations into the queue to execute asynchronously to avoid concurrent updates. Hotspot data never expires: Set a long expiration time for hotspot data or never expires to prevent cache breakdown. Current limit: Control the number of requests to access the database to prevent concurrent access from causing excessive database pressure. Use Bloom filter: Quickly determine whether the value exists. If it exists, it returns cached data. If it does not exist, it query the database.

An Introduction to Redis in PHP using Predis
Article Introduction：Core points
Redis is a popular open source data structure server that features far more than simple key-value storage thanks to its built-in data types. It is widely used by large companies and can be used as a session handler or to create online chat or live booking systems.
Redis and Memcache perform similarly in terms of basic operations, but Redis offers more features such as memory and disk persistence, atomic commands and transactions, and server-side data structures.
Predis is a flexible and fully functional PHP Redis client library that allows PHP developers to interact with Redis using PHP code. It supports a variety of Redis features, including transactions, pipelines, and clusters.
Redis commands include
