Frequent ReleasesBugfixes every 2-4 weeks
PHP 5.4 +Soon to be PHP 5.5+
All the PSRsZero through Four
Clean upRabid conventions removed.
Standalone Components
We have a few.
I18n
// Message formatting echo __("Hello, my name is {0}, I'm {1} years old", ['Sara', 12]); >>> Hello, my name is Sara, I’m 12 years old
// Decimals and integers echo __('You have traveled {0,number,decimal} kilometers in {1,number,integer} weeks', [5423.344, 5.1]); >>> You have traveled 5,423.34 kilometers in 5 weeks
Messages
echo __('{0,plural, =0{No records found} =1{Found 1 record} other{Found # records}}', [1]); >>> Found 1 record
// Simpler message ids. echo __('records.found', [1]); >>> Found 1 record
Plurals
msgid "One file removed" msgid_plural "{0} files removed" msgstr[0] "jednom datotekom je uklonjen" msgstr[1] "{0} datoteke uklonjenih" msgstr[2] "{0} slika uklonjenih"
Catalog Files

$date = new Time('2015-04-05 23:00:00'); echo $date; >>> 05/04/2015 23:00
echo Number::format(524.23); >>> 524.23
Numbers & Dates
Locale::setDefault(‘fr-FR’);
$date = new Time('2015-04-05 23:00:00'); echo $date; >>> 5 avril 2015 23:00:00 UTC
echo Number::format(524.23); >>> 524,23

Use AloneUse the i18n libs anywhere with composer.
Routing
Router::scope(‘/u‘, function ($routes) { $routes->connect(‘/name/:username’, [‘controller’ => ‘Users’, ’action’ => ‘show’]); });
// Use namespace prefixed controllers. Router::prefix(‘admin’, function ($routes) { $routes->connect(‘/articles/:action’, [‘controller’ => ‘Articles’]); });
Routing Scopes
// Classic array format. echo $this->Url->build([ ‘controller’ => ‘Users’, ‘action’ => ‘show’, ‘username’ => ‘thewoz’ ]); >>> /u/name/thewoz
echo $this->Url->build([ ‘prefix’ => ‘Admin’, ‘controller’ => ‘Articles’, ‘action’ => ‘index’ ]); >>> /admin/articles/index
Reverse Routing
Router::scope(‘/u‘, function ($routes) { // Explicit name $routes->connect(‘/friends’, [‘controller’ => ‘Friends’], [‘_name’ => ‘u:friends’]); });
echo $this->Url->build([‘_name’ => ‘u:friends’]); >>> /u/friends
Named Routes
Router::scope('/', function ($routes) { $routes->extensions(['json']); $routes->resources('Articles'); }); >>> /articles and /articles/:id are now connected.
// Generate nested resources Router::scope('/', function ($routes) { $routes->extensions([‘json’]); $routes->resources('Articles', function ($routes) { $routes->resources('Comments'); }); }); >>> /articles/:article_id/comments is now connected.
Resource Routing
Collections
Jose Lorenzo Rodriguez
Iterator Master
ImmutableMutator methods make new collections.
$items = ['a' => 1, 'b' => 2, 'c' => 3]; $collection = new Collection($items);
// Create a new collection containing elements // with a value greater than one. $big = $collection->filter(function ($value, $key, $iterator) { return $value > 1; });
// Search data in memory. match() makes a new iterator $collection = new Collection($comments); $commentsFromMark = $collection->match(['user.name' => 'Mark']);
Improved Arrays
$people = new Collection($peopleData);
// Find all the non-blondes $notBlond = $people->reject(function ($p) { return $p->hair_colour === ‘blond’; });
// Get all the people named jose $joses = $notBlond->filter(function ($p) { return strtolower($p->first_name) === ‘jose’; });
// Count by their hair colour $counts = $joses->countBy(function ($p) { return $p->hair_colour; });
Pipeline Example
class JoseFinder { public function __invoke($person) { return strtolower($person->first_name) === ‘jose’; } }
$joses = $people->filter(new JoseFinder()); $notBlond = $people->reject(new NotBlondFilter());

Use AloneCollections can be used in any project.
ORM
It is not 2005 anymore
ActiveRecord Datamapper
// Get a table gateway/mapper. $connection = ConnectionManager::get(‘default’); $articles = new ArticlesTable([‘connection’ => $connection]);
// Basic query building $query = $articles->find() ->where([‘Articles.author_id’ => $userid]) ->order([‘Articles.created’ => ‘DESC’]);
// Find some published, promoted articles $query = $articles->find(‘promoted’) ->find(‘published’);
Finding Records
// Find articles and eager load relations (1 query) $query = $articles->find() ->contain([‘Authors’, ‘Categories’]);
// Load deeply nested relations (2 queries) $query = $articles->find() ->contain([‘Authors.RecentActivities’]);
Eager Loading
// Find all the articles tagged with ‘Cat’ $query = $articles->find()->matching(‘Tags’, function ($q) { return $q->where([‘Tags.name’ => ‘Cat’]); });
// Find all the articles without the tag ‘Cat’ $query = $articles->find()->notMatching(‘Tags’, function ($q) { return $q->where([‘Tags.name’ => ‘Cat’]); });
Matching
// Do extraction and transformations $result = $articles->find() ->all() ->extract(‘title’) ->map(function ($item) { return strtoupper($item); });
// Extract and reduce $query = $articles->find()->contain([‘Tags’]); $uniqueTags = $articles->all() ->extract(‘tags.{*}.name’) ->reduce(function ($out, $tag) { if (!in_array($tag, $out) { $out[] = $tag; } return $out; }, []);
Collections+
EntitiesJust vanilla PHP objects for the most part.
namespace App\Model\Entity;
use Cake\ORM\Entity;
class Article extends Entity { protected $_accessible = [‘title’, ‘body’, ‘author_id’]; }
Article Entity
namespace App\Model\Entity;
use Cake\ORM\Entity;
class User extends Entity { protected function _getFullName() { return $this->_properties['first_name'] . ' ' . $this->_properties['last_name']; }
}
echo $user->full_name;
Virtual Fields
Inspired By SQLAlchemy
The best ORM I’ve ever used.
No Proxies, No Annotations, No Identity Map,
No Runtime Reflection
No Lazy Loading
Use aloneUse the ORM anywhere with composer.
