You know composer is a framework for maintaining PHP packages - installing them as a dependency to your project, ensuring their requirements, auto-loading classes, and much more. But you can also create a new PHP project directly from a composer package, easily. In Visual Studio Code it's even simpler.
Most of the type-safe languages, like TypeScript, C++, C#, Java, ... or Hack, .. allow you to specify not just types but also so-called generic type arguments - a way of substituting a type name with an actual type when you use it. PHP lets you to specify types for extra type-safety (and improved code completion), but generic types need to be specified inside Doc Comments. That's because the PHP language syntax itself does not know them yet.
I got an email from a user asking for help. He couldn't debug PHP application he was working on. After a little digging, we found out that he couldn't even run PHP. When executed it stopped immediately with a warning:
Your PHP application or a website might be running fluently, or you might see it takes some time to load. In both cases, it is a good practice to do performance profiling. This technique lets you know how much time all the functions in the code take, and how many times they've been called. You might see interesting results and improve the live of your users, and the live of your Web Server.
VS Code allows you to work remotely with the full-featured development environment. Even though you work remotely, you don't need to sacrifice all the great features available when you work locally - full Intellisense, navigation, refactoring, debugging and testing.
In this tutorial you'll learn how to create more than one container and communicate between them. This requires Docker compose which is a great way for local developing and testing your projects.
Welcome to the third article of PHP on Docker. In the previous article, we learned how to create two connected containers with php and nginx with the help of Docker compose, and we also talked about different environments where your software needs to work.
In the previous article, we talked about Docker and created a simple Docker Image with PHP inside Visual Studio Code. If you did not read it yet, I strongly recommend reading it before, since you'll have more context for this one. In this article, we will create a multi-container application using PHP and Nginx with the help of Docker Compose. You can see all the files we will be creating on github.
I'm sure you have already heard something about it. Docker -the technology that completely took over the software world in the past few years. This article explains what Docker is and how to use it with PHP inside Visual Studio Code.
