When I gave this talk
five months ago...

5.
I was pushing HHVM
Hard

6.
The numbers were compelling
WordPress 4.1.x with 20 concurrent users.
• Requests per second
• PHP 5.5: 256
• PHP 7: 627
• HHVM 3.7: 666
• Latency
• PHP 5.5: 78 milliseconds
• PHP 7: 32 milliseconds
• HHVM 3.7: 30 milliseconds

7.
PHP adoption rates were depressing
• PHP 5.3 — 41.4%
• Released: June 30, 2009
• End of Life: August 14, 2014
• PHP 5.4 — 30.1%
• Released: March 1, 2012
• End of Life: September 12, 2015
• PHP 5.5 — 9.3%
• Released: June 20, 2013
• End of Life: June 20, 2016
• PHP 5.6 — 1.5%
• Released: August 28, 2014
• End of Life: August 28, 2017

8.
And hosts were announcing HHVM support
• WP Engine
• DreamHost
• Pagely
• SiteGround
• Kinsta
• Etc.

9.
Legacy PHP bad

10.
But I was being myopic

11.
Don't get me wrong
HHVM is still fast

12.
But PHP is PHP

13.
PHP 7 is PHP
on steroids

14.
Let's take a look
at some numbers
boogah.org/55vs7

15.
PHP 5.5 vs. PHP 7
• WordPress (4.3.1)
• PHP 7 was 2.6 times faster than PHP 5.5
• WordPress (4.3.1) + WooCommerce (2.4.8)
• PHP 7 was 1.4 times faster than PHP 5.5
• WordPress (4.3.1) + bbPress (2.5.8)
• PHP 7 was 6.6 times faster than PHP 5.5
• WordPress (4.3.1) + BuddyPress (2.3.4)
• PHP 7 was 4.7 times faster than PHP 5.5

16.
All these numbers are
pretty awesome

17.
However, 67.9% of all PHP sites
are currently powered by versions
that should be considered dead

18.
They have ceased to be

19.
Why should anyone give a !?

20.
Nobody builds sites for the past
You build them for the future

21.
The futch

22.
vagrantup.com

23.
Vagrant creates & configures
virtual development environments

24.
This means
less yak shaving & more working

25.
Varying Vagrant Vagrants
is the industry standard
for WordPress development

26.
There is another

27.
It does PHP 7 & HHVM
And it was made for WordPress development

28.
HGVgithub.com/wpengine/hgv

29.
Built by WP Engine
for our Mercury platform

30.
No matter where you host your site,
you can use HGV to test your code

31.
HGV
• Built with members of the 10up team
• Work on your code under PHP 5.5, PHP 7 & HHVM at the same time
• Provision multiple sites using YML files
• Debugging & benchmarking tools
• Xdebug
• XHProf
• Siege
• query-monitor
• debug-objects
• debug-bar

32.
Installing HGV is easyish

33.
Prerequisites
• Git
• VirtualBox or VMware
• Vagrant
• The Vagrant Ghost plugin
boogah.org/hgv-prereq
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install git
brew install caskroom/cask/brew-cask
brew cask install vagrant
brew cask install virtualbox
vagrant plugin install vagrant-ghost

34.
Install
cd ~
mkdir vagrant
cd vagrant
git clone --recursive https://github.com/wpengine/hgv.git
cd hgv
vagrant up

35.
While HGV installs, make yourself a drink
It should only take about 30 minutes

36.
Get to work
• Local file access
• Use your favorite text editor!
• [HGV_dir]/hgv_data/sites/[sitename]/
• [HGV_dir]/hgv_data/sites/[sitename]/wp-content/[plugins|themes]/
• SSH
• vagrant ssh
• phpMyAdmin
• admin.hgv.test/phpmyadmin/

37.
Just import your site
and see what breaks

38.
PHP 7 & WordPress
boogah.org/php7wp

39.
Switching your environment
is a piece of cake

40.
Force your site to PHP 7
vagrant ssh
sudo nano -w /etc/nginx/conf.d/www-[sitename].conf

41.
Force your site to PHP 7
Change this:
cache.php.example.test php;
php.example.test php;
To this:
cache.php.example.test php7;
php.example.test php7;
Save your changes!

42.
Force your site to PHP 7
service nginx restart
