In this post we will explore how to expose PHP data to a Node application. We will build a simple hello world app to demonstrate this and then build a chat application where we can expose chat history from a database to users as well

What are Magic quotes? Magic Quotes is a function that is designed to help escape potentially Malformed data inputs in PHP forms. The problem with Magic Quotes is that the function escapes not only suspicious characters but inverted commas and speech marks as well.
Sessions are designed to exist within a current user session. They also run purely on the server side and unlike Cookies nothing is pushed to the browser’s cache (client side). So, what are sessions good for? Imagine you have a shopping cart site that requires a login
