Frequent Releases
Bugﬁxes every 2-4 weeks

All the PSRs
Zero through Four

Clean up
Rabid conventions removed.

Standalone
Components
We have a few.

// 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 CakeI18nTime;
use CakeI18nNumber;
$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 Alone
Use the i18n libs anywhere with composer.

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

Jose Lorenzo
Rodriguez
Iterator Master

Immutable
Mutator 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());
Pipeline ++

Use Alone
Collections can be used in any project.

// 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)
->contain([‘Authors’, ‘Categories’]);
// Load deeply nested relations (2 queries)
->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+

Entities
Just vanilla PHP objects for the most part.

namespace AppModelEntity;
use CakeORMEntity;
class Article extends Entity
{
protected $_accessible = [‘title’, ‘body’, ‘author_id’];
}
Article Entity

namespace AppModelEntity;
use CakeORMEntity;
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

Use alone
Use the ORM anywhere with composer.

What’s Next
• New DateTime library, replacing Carbon
• Polymorphic Associations
• PSR7 Support
• Value Objects

Thank You.
