What is Alternative PHP Cache?
Alternative PHP Cache (APC) is a free, open source opcode cache for PHP. It is designed to improve the performance of PHP applications by caching bytecode of PHP scripts in memory, reducing the amount of time needed to parse and execute scripts on each request.
Some key features of APC include:
Stores precompiled PHP bytecode in shared memory, eliminating need to load and parse scripts on each request
Decreases CPU usage and improves page load times
Includes a bytecode cache, variable store and user data cache
Easy to install and configure, works right out of the box
Compatible with most PHP applications
Supports file upload progress tracking
Allows caching of user variables between requests
Provides admin page to monitor cache performance
Integrates with common PHP frameworks like Drupal and WordPress
Open source with an active development community
Overall, APC is a mature, stable and efficient opcode cache for optimizing PHP apps. It can provide substantial performance and scalability improvements for high traffic PHP sites and apps with minimal config changes. The active development community ensures continued support across future PHP versions.
