I have developed in PHP since 1998. It was version 3.x at that time, and it was a fairly advanced server side technology for creating dynamic web page content.
Things have changed a lot since those times, and now with MVC frameworks, and advanced language features, PHP has done a good job staying up to date. In work I do, I like to use the advanced features = and almost have to – for development in my favorite MVC framework – Yii2.
I have some PHP repos on github.
