This document discusses PHP environments and tools. It provides an overview of PHP versions and improvements over time. It also summarizes Laravel, a popular PHP framework, and common tools used in PHP development like Composer and Valet. Production environments, security, optimization, monitoring, and background jobs are also covered at a high level.

● Easy for beginners
● Easy to "deploy"
● PHP mixed in HTML
● No conventions for
function names
Evolution
< 5.3 Lixo
5.3 Namespaces, closures (anonymous functions)
5.4 Traits, [] for arrays
5.5 OPcache, finally on try blocks
5.6 Agument unpacking (...$args)
7.0 Performance (thanks to HHVM), return types, scalar
types (int, float, string, bool), improved exceptions
7.1 Nullable types (?int), catch multiple exceptions

5. PHP?!
Community
Composer / Packagist / Autoloader
Dotenv
PHP FIG and PSRs
Standards
PSR 1 - Basic Coding
PSR 2 - Coding Style Guide
PSR 3 - Logger Interface
PSR 4 - Autoloading
PSR 5 - Caching Interface
PSR 7 - HTTP Message Interface

6. Laravel Framework
Released in 2011
Key Features
● Routes
● Controllers
● Service Container & Dependency Injection
● Broadcasting (Pusher or socket.io)
● Migrations (tables)
● Eloquent ORM (sql)
● Artisan command line
● Queues (beanstalkd, redis, amazon sqs)
● Unit Testing
● Laravel Elixir for gulp and Laravel Mix for webpack

7. Modern PHP

8. Laravel x Rails

9. Local Environment

10. Require mysql and php local
$ composer global require laravel/valet
$ valet park
$ valet paths
.dev
$ valet domain .etc
Valet

11. /**
* Determine if the driver serves the request.
*
* @param string $sitePath
* @param string $siteName
* @param string $uri
* @return bool
*/
public function serves($sitePath, $siteName, $uri)
{
return is_dir($sitePath.'/wp-admin');
}

13. Production Environment
