Purpose

• If you're new to Drupal, go and try it
• If you've used it before, re-try it

About Drupal

• Drupal is an open source, PHP content management system
• 16 years old
• Drupal 8 was released in November 2015
• Non-BC changes between major versions
• Mostly procedural code prior to D8
• Drupalisms

• Drupal was released on Jan 15, 2000
• Drupal 8 took 4 years to complete - started in 2011

Entities(ish)

• Everything uses stdClass
• No consistency between models

Hooks

// hello.module

/**
 * Implements hook_menu()
 */
function hello_menu() {
  $items['hello-world'] = array(
    ...
  );

  return $items;
}

Theme functions

$items[
  l('Foo', 'foo'),
  l('Bar', 'bar'),
];

return theme('item_list', ['items' => $items]);
          

• Foo
• Bar

• Drupal 8 Web Services initiative lead
• PHP-FIG representative

Symfony

• Core developed using Symfony components
• Minimum PHP version requirement
• PHP code in classes
• No more functions (almost)
• Namespaces
• PSR-0 PSR-4 Autoloading
• Dependency injection
• Full test coverage
• Consistency!

• .php files rather than .inc
• 5.5.9 minimum

Symfony components

http://symfony.com/projects/drupal

• Guzzle replacing drupal_http_request() - 311 lines removed

YAML

name = Example
core = 7.x
package = Custom

dependencies[] = entity

files[] = a.inc
files[] = b.inc
            

name: Example
type: module
core: 8.x
package: Custom

dependencies:
- entity
            

Routing (D7)

hello.module

function hello_menu() {
  $items['hello-world'] = [
    'title' => 'Hello, PHPSC',
    'page callback' => 'hello_page_callback',
    'access arguments' => ['access content'],
  ];

  return $items;
}
            

Routing (D8)

hello.routing.yml

hello.view:
  path: /hello-world
  defaults:
    _title: 'Hello, PHPSC'
    _controller: '\Drupal\hello\Controller\PageController::helloView'

• CKEditor
• Zend
• Composer
• Stack
• Guzzle
• Twig
• PhpUnit

Composer

Contrib

• Web Profiler - Symfony WebProfiler Bundle as a Drupal 8 module
• Composer Manager - adds a GUI for Composer dependencies
• xautoload - PSR-4 support for Drupal 7

Libraries first

• Commerce Guys/Drupal Commerce
• Non-Drupal problems fixed in libraries and Drupal modules were written with libraries as dependencies.

Drupal Console

Going forward

More to do?

• Still some Drupalisms
• PSR-2
• GitHub/Packagist
• Drupal CI

• Hooks, render arrays
• Code repsositories and packaging still done on Drupal.org

In Summary

• Lowered the barrier to entry for PHP Developers
• Made me a better Developer
• More transferable knowledge and skills
• Changed perspective
