Tim Bray “All the PHP code I’ve seen in that experience has been messy, unmaintainable crap. Spaghetti SQL wrapped in spaghetti PHP wrapped in spaghetti HTML, replicated in slightly- varying form in dozens of places”

COMPOSER Dependency Manager for PHP Created by Jordi Boggiano and Nils Adermann Thank you guys!

Slide 40

Slide 40 text

Fabien Potencier “PHP has a better dependency manager than any other languages”

Slide 41

Slide 41 text

curl -sS https://getcomposer.org/installer | php Can be installed globally and locally

Slide 42

Slide 42 text

The problem that Composer solves is this: You have a project that depends on a number of libraries Some of those libraries depend on other libraries You declare the things you depend on Composer finds out which versions of which packages need to be installed, and installs them (meaning it downloads them into your project)

Slide 43

Slide 43 text

Declaring dependencies composer.json { "name": "zendframework/skeleton-application", "description": "Skeleton Application for ZF2", "license": "BSD-3-Clause", "keywords": [ "framework", "zf2" ], "homepage": "http://framework.zend.com/", "require": { "php": ">=5.3.3", "zendframework/zendframework": "2.2.*", "aws/aws-sdk-php-zf2": "1.2.1", "league/flysystem": "0.4.*@dev" } }
