On the one hand, you want to deploy changes to the live site QUICKLY (for, say, a Highly Critical security update).

On the other hand, you want make changes SAFELY, ie. you don't want it to break the site.

Testing is good. Automated testing is great.

But what if you simply didn't have the resources to comprehensively test the change (either manually or automatically)?

A Single Page Application (SPA) offers a desktop experience to users of a web application by loading a single HTML page, and dynamically updating it as required without reloading. However, a Symfony application may have hundreds of classes, and in a basic application we end up with lots of files we don’t really need.

The latest versions of Symfony (2.8 and 3.0) introduce us to the concept of a Single File Application (SFA) – a super-slim application or micro-framework implemented in one file.

Sooner or later, there will come a time when you will need to migrate your projects to different PHP versions. How will you check if you’re compatible with a PHP version different to the one you’ve been developing on?

PHP is one of the most popular programming languages around the world, and the recent PHP 7 release made this server-side programming language better and more stable than ever.

Hey, I got this new web project, but to be honest I haven’t coded much web in a few years and I’ve heard the landscape changed a bit. You are the most up-to date web dev around here right?

-The actual term is Front End engineer, but yeah, I’m the right guy. I do web in 2016. Visualisations, music players, flying drones that play football, you name it. I just came back from JsConf and ReactConf, so I know the latest technologies to create web apps.

One of the problems of PHP as a programming language is the fact that you can only have single inheritance. This means a class can only inherit from one other class.

However, a lot of the time it would be beneficial to inherit from multiple classes. For example, it might be desirable to inherit methods from a couple of different classes in order to prevent code duplication.

This problem can lead to class that has a long family history of inheritance which often does not make sense.
