Why should we cache query results? Caching query results can greatly improve script execution time and resource requirements. Caching SQL query results also allows you to post-process the data. If you use file caching to store the output of all scripts (the normal method of HTML is very resource-intensive and adversely affects the performance of the script). This can only be reconciled by the large amount of returned data obtained and the location of the database server. .Although continuous connections can improve the load when connecting to the database, it consumes very memory resources. If a large amount of data is obtained, the entire storage time will be very short. Therefore, the StashPHP caching library is specifically designed to solve this caching problem in PHP.
