HttpFoundation (Symfony Component)

Il componente HttpFoundation definisce un livello orientato agli oggetti per la specifica HTTP.

In PHP la richiesta è rappresentata da alcune variabili globali ( $_GET, $_POST, $_FILES, $_COOKIE, $_SESSION, ...) e la risposta è generata da alcune funzioni ( echo, header(), setcookie(), ...).

Il componente Symfony HttpFoundation sostituisce queste variabili e funzioni globali PHP predefinite con un livello orientato agli oggetti.

Test 2

Verifica metodo ->query->get()
Usa la query string '?foo=bar'

Simula il test qui: https://www.symfony.andreamodolo.it/src/httpfoundation/index.php? foo=bar

code:


result:


$request->query->get('foo'): 
^ "bar"

$request->query->get('bar'): 
^ null

$request->query->get('bar','defaultValue'): 
^ "defaultValue"

$request->query->get('bar'): 
^ null

Test 3

Verifica metodo ->query->all()
Usa la query string '? foo=bar &baz=john &name=Jack &foo2[bar]=baz'

Simula il test qui: https://www.symfony.andreamodolo.it/src/httpfoundation/index.php? foo=bar &baz=john &name=Jack &foo2[bar]=baz

code:


result:


$request->query->all(): 
^ array:1 [
  "foo" => "bar"
]

$request->query->all()['foo']: 
^ "bar"

$request->query->all()['foo2']: 
^ null

$request->query->all()['foo2']['bar']: 
^ null

$request->query->count(): 
^ 1

Test 4

Simulating a Request
Invece di creare una richiesta basata sui globali PHP, si può anche simulare una richiesta

code:


result:


Request::create( ... ):
