All Aboard for Laravel 5.1 - Jason McCreary - php[world] 2015
A short rant about frameworks
Choose wisely and code carefully
2

Talk the Talk
1. What’s New in Laravel 5.0
2. Upgrading from Laravel 4.2
3. What’s New in Laravel 5.1
4. What’s coming in Laravel 5.2
3

The Goal
“To get you familiar with the new features in Laravel so
you are comfortable upgrading your projects to 5.1”
4

Why Upgrade?
“Laravel 5.1 is the first release of Laravel to receive
long term support. Laravel 5.1 will receive bug fixes
for 2 years and security fixes for 3 years.This support
window is the largest ever provided for Laravel and
provides stability and peace of mind for larger,
enterprise clients and customers.”

What’s New…
In Laravel 5.0
6

New Folder Structure
• Follows PSR-4 naming conventions
• App namespacing
• Models live in the default namespace
• Everything related to HTTP lives under Http/
(controllers, middleware, requests)
• Views live outside the App namespace within
resources/.
7

Folder Structure

App Folder

4.2 5.0

Namespacing
<?php namespace App; 
 
// ...
 
class User extends Model { 
// ... 
}
10

Namespacing
<?php namespace AppHttpControllers; 
 
class HomeController extends Controller {
 
public function index() 
{ 
return view('home'); 
} 
}
11

Namespacing
"autoload": { 
"classmap": [ 
"app/commands", 
"app/controllers", 
"app/models", 
"app/database/migrations", 
"app/database/seeds", 
"app/tests/TestCase.php" 
] 
},
12
"autoload": {
"classmap": [
"database"
],
"psr-4": {
"App": "app/"
}
},
4.2 5.0

New Objects
• Events are now objects, not strings!
• Command objects allow simpler job processing
• Requests are now objects
• Middleware objects to replace Filters
13

Middleware
“HTTP middleware provide a convenient mechanism
for ﬁltering HTTP requests entering your application.”
14

Middleware
 
class HomeController extends Controller { 
public function __construct() 
{ 
$this->middleware('auth'); 
}
// ... 
}
15

Middleware
<?php namespace AppHttpMiddleware;
use Closure;
class TimeoutMiddleware {
public function handle($request, Closure $next) {
if (abs(time() - $request->input(‘ttl’)) > 300) {
return redirect('timeout');
}
return $next($request);
}
}
16

Form Request Objects
“A simple way to customize request validation
automatically.”
17

Form Request Objects
<?php namespace AppHttpRequests;
class RegisterRequest extends FormRequest {
public function rules() {
return [
'email' => 'required|email|unique:users',
'password' => 'required|confirmed|min:8'
];
}
}
18

Controller Method Injection
“In addition to constructor injection, you may now
type-hint dependencies on controller methods. These
objects will be resolved and available along with any
route parameters.”
19

Controller Method Injection
public function register(
RegisterRequest $request,
RegistrationRepository $registration)
{
// ...
}
20

ControllerValidation
"If FormRequests are a little too much, the Laravel 5
base controller now includes a
ValidatesRequests trait.This trait provides a
simple validate() method to validate incoming
requests."
21

ControllerValidation
public function register(Request $request)
{
$this->validate($request, [
'email' => 'required|email|unique:users',
'password' => 'required|confirmed|min:8'
]);
}
22

Environment Configuration
“Laravel 5 uses the DotEnv library to condense all
configuration values into a single .env file. These
values get loaded into $_ENV and available through the
env() helper method.”
23

APP_ENV=local 
APP_DEBUG=true 
APP_KEY=SomeRandomString 
 
DB_HOST=localhost 
DB_DATABASE=homestead 
DB_USERNAME=homestead 
DB_PASSWORD=secret 
 
CACHE_DRIVER=file 
SESSION_DRIVER=file
24
<?php
return array(
'APP_KEY' => 'secretkey',
);
4.2 5.0

25
<?php 
 
return [
 
'debug' => env('APP_DEBUG'), 
// ...
 
'key' => env('APP_KEY', 'SomeRandomString'), 
 
// ... 
];

Artisan Updates
• Now includes several make commands to generate
common objects
• tinker is now backed by Psysh for a more powerful
REPL
• route commands for listing and caching routes
26

Authentication
“User registration, authentication, and password reset
controllers are now included out of the box, as well as
simple corresponding views.”
27

User Model (4.2)
<?php 
 
use IlluminateAuthUserTrait; 
use IlluminateAuthUserInterface; 
use IlluminateAuthRemindersRemindableTrait; 
use IlluminateAuthRemindersRemindableInterface; 
 
class User extends Eloquent implements UserInterface,
RemindableInterface { 
 
use UserTrait, RemindableTrait; 
 
protected $table = 'users'; 
protected $hidden = array('password', 'remember_token'); 
}
28

User Model (5.0)
 
use IlluminateAuthAuthenticatable; 
use IlluminateDatabaseEloquentModel; 
use IlluminateAuthPasswordsCanResetPassword; 
use IlluminateContractsAuthAuthenticatable as AuthenticatableContract; 
use IlluminateContractsAuthCanResetPassword as
CanResetPasswordContract; 
 
class User extends Model implements AuthenticatableContract,
CanResetPasswordContract { 
 
use Authenticatable, CanResetPassword; 
 
protected $table = 'users'; 
protected $fillable = ['name', 'email', 'password']; 
protected $hidden = ['password', 'remember_token']; 
}
29

Blade
“By default, Laravel 5.0 escapes all output from both
the {{ }} and {{{ }}} Blade directives. A new
{!! !!} directive has been introduced to display raw,
unescaped output.”
30

Libraries and Packages
• Laravel Elixir - asset management
• Laravel Socialite - authentication with Oauth services
• Flysystem - ﬁlesystem abstraction library
• Laravel Scheduler - command manager
31

Upgrading Laravel
From 4.2 to 5.0
32

Two Approaches
• “New move-in”
• “Update in-place”
33

What to do?
“As always, it depends. However, the documentation
recommends migrating your 4.2 app to a new Laravel 5
app. So, new move-in it is.”
34

Basic Steps
1. Create a new Laravel 5 app
2. Migrate configuration
3. Move app files
4. Add namespacing
5. Review Bindings
6. Miscellaneous changes
7. Blade Tag changes
8. Update dependencies
9. Cross fingers
35

Do not pass 5.0!
“Going directly to 5.1 will make the migration more
complicated as there are signiﬁcant changes between
5.0 and 5.1. Do not pass 5.0. Otherwise you will not
collect $200 and you will go to jail.”
36

Create new Laravel 5 app
composer create-project laravel/laravel --prefer-dist
37

Create new Laravel 5 app
composer global require “laravel/installer=~1.1”
laravel new project-name
38

Migrate Configuration
1. Copy configuration from your 4.2 app’s env.php
to .env
2. Compare configurations from your 4.2 app’s
config/
3. Recreate environment configurations from your 4.2
app’s config/env/ to.env
4. Update environment configurations to use env()
39

“Be sure to leave .env.example ﬁle in your project.
It should contain placeholder values that will make it
easy for other developers to copy and conﬁgure for
their environment.”
40

“When managing multiple environments, you may ﬁnd it
easiest to create several .env ﬁles and symlink
the .env within each environment.”
41

Move Files
42
4.2 5.0

Move Files
• routes.php to app/Http/routes.php
• app/views to resources/views
• app/database to database/
43

Add namespace
“You do not need to do this.You can keep everything in
the global namespace and add the paths to the
classmap just as in Laravel 4.2. However, not doing
so carries over technical debt as your project will not
truly follow Laravel 5.0’s conﬁguration.”
44

Add namespace
 
class YourController extends Controller {
// ... 
} 
45

Add namespace
 
class YourModel extends Eloquent {
// ... 
} 
46

Review Bindings
"Move any service container bindings from start/
global.php to the register method of the app/
Providers/AppServiceProvider.php ﬁle."
47

Miscellaneous Changes
•SoftDeletingTrait is now SoftDeletes
•User Authentication changes
•Pagination method changes
•Oh yeah, and the Form and Html Facades are gone.
48

Blade Changes
1. Cry
2. Bargain
3. Face reality
4. Start changing every {{ }} to {!! !!}
5. Remove all blade comment tags {{-- --}} (you
should have known better)
6. Smile
49

Update your dependencies
"Review your dependencies then run composer
update"
50

Cross ﬁngers
