Salzburg WebDev Meetup PHP Symfony
This document summarizes a presentation about PHP and Symfony frameworks. It discusses PHP's history and usage, strengths like being easy to get started with, and weaknesses like inconsistent code. Symfony is introduced as a popular PHP framework that uses MVC architecture and loose coupling. The presentation demonstrates filtering an array with PHP and concludes by thanking the audience and asking if they have any other questions.
