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

use Cake\I18n\Time; use Cake\I18n\Number;

$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

Numbers & Dates

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());

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.
