 Repository: https://github.com/TrafeX/docker-php-nginx
 
 
 * Built on the lightweight and secure Alpine Linux distribution
 * Multi-platform, supporting AMD4, ARMv6, ARMv7, ARM64
 * Very small Docker image size (+/-40MB)
-* Uses PHP 8.0 for better performance, lower CPU usage & memory footprint
+* Uses PHP 8.1 for better performance, lower CPU usage & memory footprint
 * Optimized for 100 concurrent users
 * Optimized to only use resources when there's traffic (by using PHP-FPM's `on-demand` process manager)
 * The services Nginx, PHP-FPM and supervisord run under a non-privileged user (nobody) to make it more secure
 * The logs of all the services are redirected to the output of the Docker container (visible with `docker logs -f <container name>`)
 * Follows the KISS principle (Keep It Simple, Stupid) to make it easy to understand and adjust the image to your needs
