PHP Extension Versions Checker

Overview

This simple PHP command allows you to list all loaded PHP extensions along with their versions. It utilizes the ReflectionExtension class to provide detailed information about each extension.

Usage

php -r '$all = get_loaded_extensions(); foreach($all as $i) { $ext = new ReflectionExtension($i); $ver = $ext-&gt;getVersion(); echo "$i - $ver" . PHP_EOL;}'

Raspberry Pi on Internet via reverse SSH tunnel

HackerNews discussed this with many alternative solutions: https://news.ycombinator.com/item?id=24893615

I already have my own domain name: mydomain.com. I wanted to be able to run some webapps on my Raspberry Pi 4B running perpetually at home in headless mode (just needs 5W power and wireless internet). I wanted to be able to access these apps from public Internet. Dynamic DNS wasn't an option because my ISP blocks all incoming traffic. ngrok would work but the free plan is too restrictive.

I bought a cheap 2GB RAM, 20GB disk VM + a 25GB volume on Hetzner for about 4 EUR/month. Hetzner gave me a static IP for it. I haven't purchased a floating IP yet.

Error

The authenticity of host 'github.com (140.82.113.4)' can't be established.

Fix

ssh-keyscan github.com >> ~/.ssh/known_hosts
