THPUG & HotelQuickly Meetup

PHP Frameworks, or how I learned to stop worrying and love the code.

Who are we?Thailand PHP User Group - A group for bringing together PHP users in Thailand

HotelQuickly - The Number 1 last minute booking app in Asia Pacific

Alex Stansfield - Software Development Manager at Gomeeki, 12 years PHP developer

Topics for the eveningWhat is a Framework?Why would I want to use one?What kind of Frameworks are there?Full Stack Top Three (Laravel, Symfony, Nette)Micro Frameworks (Silex, Slim3, Lumen)BenchmarksHQ Talk: Writing Framework Independent CodeQuestions and Discussion

What is a Framework?“Standard Solution to Common problems”

All the code you used to write or pull from your other projects packaged up for you

Provides a structure to your codeCommunity

Why would you want to use one?Saves you from reinventing the wheelCommunity Resources (plugins, tutorials)Open Source

Some of the best minds involvedMany eyes to review the codeContribute

Keep code consistent between developers

What kind of frameworks are there?Frameworks mostly fall into three groups:

Micro FrameworksFull Stack FrameworksContent Management Frameworks

What is a Micro Framework?Minimal frameworks giving you a fast shell for your code

Dependency Injection Container

RoutingMiddleware SupportRequest and Response

HandlingBasic Error Handling

Routinghttp://example.com/my/bloghttp://example.com/my/blog/edit

In the Past/var/www/site/my/blog/index.php/var/www/site/my/blog/edit/index.php

Now/var/www/site/public/index.php

RequestEverything from the Request wrapped up in easy to access Object.

$_POST[‘this’], $_GET[‘that’], $_SERVER[‘REQUEST_METHOD’]

$request->has(‘this’);$request->get(‘that’);$request->getMethod();$request->getHeader(‘Content-Type’);

Routing & Requesthttp://example.com/blog/2015/08/29

Route - /blog/{year}/{month}/{day}

Request Populated With:year: 2015month: 08day: 29

Example$app->get('/hello[/{name}]', function ($request, $response) { $response->write("Hello, " . $request->get('name')); return $response;})->setArgument('name', 'World!');

GET /helloHello, World!

GET /hello/alexHello, alex

What is a Full Stack Framework?Contains many components to help you rapidly develop large applications

Full Stack Top Three

Sitepoint Survey into PHP Framework popularity from March 2015

The Full Stack Big ThreeSitepoint Survey into PHP Framework popularity from March 2015

1.Laravel2.Symfony23.Nette

LaravelAiming to make web development easierBuilds upon third party componentsFacade provides easy access to services More components than other frameworksHomestead Vagrant boxSuited to all sizes of project

IlluminateIlluminate wraps a number of 3rd party

libraries and framework componentsProvides more features (Queues, Cloud)Provides more choice with ContractsFairly tight coupling

FacadesStatic interface to classes that are in service

containerFacades for existing Illuminate servicesCan create your own facades to access your

servicesSeen by some as promoting bad practiseInjecting Services is still available

Laravel - Round UpLarge community and user baseVery easy to pick up and configureIlluminate provides more out of the boxHomestead helps you get developingDocumentation focuses more on FacadeGood for projects of any sizeQuite Tightly coupled so harder to leave

Symfony2Heavy Inspiration from Ruby on RailsBuilding Robust Enterprise ApplicationsHighly CustomisablePowerful Profiling and Debug toolsIncludes popular 3rd party componentsMany useful Bundles availableLearning curve can be steep

Profiling and Debug Tools

Third Party BundlesUser Registration, Login and ProfileOAuth Interface to many social loginsAutomatic Rest HandlingWeb Service Api DocumentationImage ManipulationEasy Access to Third Party Libraries

Symfony2 - Round UpLarge community and user basePowerful Profiling and Debugging ToolsLoosely Coupled and 3rd party ComponentsVery configurable (a pro and a con)Can be daunting to new users and steeper

learning curveBetter for larger projects

NetteMature but little known outside CzechDesigned around MVP over MVCTracy debugger and profilerDetailed Error ReportingLatte templating componentQuite loosely coupled components

Tracy - Debugging and Errors

Latte - Templating EngineTemplate InheritanceContext aware Escaping

Context Aware Escaping

Value of $movie is 'Amarcord & 8 1/2'

Macros & FiltersMacros Surrounding HTML

Macros Inline HTML

Latte - Templating EngineTemplate InheritanceContext aware EscapingMacros inline in HTML tags (like AngularJS)Filters for content manipulationUser defined Filters and MacrosCompiles templates to PHP so very fastNo dependencies on other libraries

Latte vs Blade Dependencies

Nette - Round UpEasy learning curveUseful debugger and profilerGreat Error reporting in dev modeFantastic Templating EngineSmall community outside Czech RepublicPlacement on Sitepoint survey will bring it

more attention

Stack Overflow Tag Popularity

Micro FrameworksVery minimal installNo path structure (most of the time)Much faster than Full Stack FrameworksIdeal for small projects, quick micro services

or command line applications

SilexClosely related to Symfony2Uses Pimple v1 and Symfony2 ComponentsWide range of Official and Third Party Service

ProvidersVersion 2 under development

Slim 3Still in BetaFollow up to the very fast Slim 2Embraces Standards

container-interop interfacePSR-7 Requests and Responses

Routing with Nickc’s FastRouteAimed at Web Applications

“What do you use?”

“What should I use?”

Framework Independent Codea.k.a Framework Agnostic

What is it about?

Architectures/Patterns●DDD (Domain-Driven Design)●Ports & Adapters (Hexagonal Architecture)●Dependency Inversion/Injection Principle

Domain-Driven Design“Domain-driven design is not a

technology or a methodology. DDD provides a structure of practices and

terminology for making design decisions that focus and accelerate

software projects.” Eric Evans

Hexagonal Architecture“Allow an application to equally be driven by users,

programs, automated test or batch scripts, and to be developed and tested in isolation from its eventual run-time

devices and databases” - Alistair Cockburn

Hexagonal Architecture

High-level modules should not depend on low-level modules. Both should depend on abstractions.

A code is worth a thousand words!

Dependency Inversion Principle
