PHP Web Chat system

As a 16 year old I started building my own website and discovered a cool Perl based chat script I wanted to run on my Raspberry Pi. The performance was poor though, because it was all file based and not using a database. So I’ve decided to port that script to PHP and migrate to using am SQL database for data storage, rather than having a file that is locked and re-written to disk every time someone calls the URL. It was my first big PHP project and throughout the years I’ve had many improvements to add after learning how to do it better. From a small hobby project it developed into becoming one of the most popular chat systems used on daknet sites nowadays.
