The document discusses various local development environments for PHP applications, including built-in PHP servers, Laravel Valet for macOS, LAMP/WAMP/MAMP stacks, virtual machines, and Docker. It emphasizes the ease of use, setup, and benefits of each environment for testing and development, while also cautioning against using certain tools in production. The document also highlights tools like Composer and Vagrant for dependency management and reproducible environments.

6. LOCAL DEVELOPMENT
LARAVEL VALET
▸ Mac only
▸ Very easy to get up and running (with Composer)

7. LOCAL DEVELOPMENT
▸ Composer is a tool for dependency management in PHP. It
allows you to declare the libraries your project depends on
and it will manage (install/update) them for you.
▸ Not a package manager. It manages dependencies on a per-
project basis, installing them in a vendor directory within
your project.

21. LOCAL DEVELOPMENT
LAMP / WAMP / MAMP
▸ Linux / Windows / Mac

if you’re not familiar with the command line
▸ If you don’t need it anymore, just delete it
▸ https://www.mamp.info / http://www.wampserver.com/en

22. LOCAL DEVELOPMENT
LAMP / WAMP / MAMP

23. LOCAL DEVELOPMENT
LAMP / WAMP / MAMP
▸ Linux is a bit trickier as you need to install each component
via your distribution’s package manager
▸ Use aptitude (Debian, Ubuntu), yum (RHEL / CentOS)

24. LOCAL DEVELOPMENT
LAMP / WAMP / MAMP
$ sudo apt-get install nginx
$ sudo apt-add-repository ppa:ondrej/php
$ sudo apt-get update
$ sudo apt-get install php7.0-cli php7.0-dev
php-curl php-mysql php-mbstring php-7.0-fpm…
$ …
$ sudo apt-get install mariadb-server

25. VIRTUAL MACHINE

26. LOCAL DEVELOPMENT
VIRTUAL MACHINE
▸ VirtualBox (Free)
▸ VMWare Fusion (~$100)
▸ Parallels Desktop (~$100)
▸ VMWare Workstation (~$300)

27. LOCAL DEVELOPMENT
VIRTUAL MACHINE
▸ Irrespective of your virtualisation software, you get a self-
contained, full operating system
▸ Allows you to contain your LAMP install
▸ Easy to replicate your production environment
▸ Don’t install any development software on your host machine
▸ Make a mistake? Blow away the image and start over!
▸ Resource (memory, CPU, hard disk) intensive

28. LOCAL DEVELOPMENT
VIRTUAL MACHINE - VAGRANT
▸ Create and configure lightweight, reproducible, and portable
development environments
▸ Saves you having to run install steps manually every time
▸ Don’t worry about missing a piece of software
▸ Makes disposable or single-project machines simple
▸ Commit your Vagrantfile to version control so other
developers will have exactly the same development
environment when they checkout your code

29. LOCAL DEVELOPMENT
VIRTUAL MACHINE - VAGRANT
▸ You can even build your base images and reuse them over
and over again
▸ Reduces the time it takes to get up and running on new
projects
▸ Using images means you have the base image as well as one
or more instances on your machine taking up disk space
▸ More info at https://www.vagrantup.com

30. LOCAL DEVELOPMENT
VIRTUAL MACHINE - HOMESTEAD
▸ Another Laravel product, Homestead allows you to get up
and running with a modern, pre-packaged development
environment
▸ Ubuntu 16.04
▸ Git
▸ PHP 7
▸ Nginx
▸ MySQL / MariaDB
▸ PostgreSQL
▸ Composer
▸ Node
▸ Redis / Memcached
▸ Beanstalkd

34. DOCKER
I AM NOT AN EXPERT IN
BUT I’LL TRY ANYWAY

35. LOCAL DEVELOPMENT
DOCKER - WHY?
▸ Faster delivery of your applications
▸ Deploying and scaling are easier
▸ Achieve higher density and run more workloads

36. LOCAL DEVELOPMENT
DOCKER - THREE KEY COMPONENTS
▸ Images - the build component
▸ Registries - the distribution component
▸ Containers - the run component

37. LOCAL DEVELOPMENT
DOCKER - HOW IS IT DIFFERENT TO VIRTUALISATION?
▸ Virtual machines include the application, the necessary
binaries and libraries, and an entire guest OS
Infrastructure
Host Operating System
Hypervisor
Guest OS
Bins / Libs
App 1
Guest OS
Bins / Libs
App 2

Bins / Libs
App 3

38. LOCAL DEVELOPMENT
DOCKER - HOW IS IT DIFFERENT TO VIRTUALISATION?
▸ Virtual machines include the application, the necessary
binaries and libraries, and an entire guest OS - tens of GBs
▸ With containers, you have a single operating system, and
each container shares the operating system kernel with other
containers

39. LOCAL DEVELOPMENT
DOCKER - HOW IS IT DIFFERENT TO VIRTUALISATION?
▸ Virtual machines include the application, the necessary
binaries and libraries, and an entire guest OS - tens of GBs
▸ With containers, you have a single operating system, and
each container shares the operating system kernel with other
containers - tens of MBs
▸ Because of this, a single server can host many more
containers than Virtual Machines. VMs can take several
minutes to boot, containerised apps start almost instantly

40. ▸ Containers include the application and all of its dependencies, but
share the kernel with other containers, running as isolated processes in
user space. Docker containers are not tied to any specific infrastructure.
▸ Shared parts of the operating system are read only, while each
container has its own mount for writing.

41. LOCAL DEVELOPMENT
DOCKER - HOW DOES IT WORK?
▸ Docker is written in Go and makes use of several kernel
features to deliver its functionality
▸ Namespaces
▸ Control groups
▸ Union file systems
▸ Container format

42. LOCAL DEVELOPMENT
DOCKER - SHARING AND COLLABORATION
▸ Storing, distributing, and managing Docker images is easy
with Docker Hub. Any updates and changes are shared with
others. History is automatically tracked.
▸ Collaborate with others simply by shipping your container. If
your frontend team needs to work with the API you’re
building, all they have to do is spin up up the Docker
container.

43. LOCAL DEVELOPMENT
DOCKER - SCALABILITY
▸ Because containers are lightweight, they take seconds to
spin up and down
▸ This makes it easy to scale out your application during peak
times, and scale down during quiet periods
▸ A lot of this can be automated
