Comment extraire les détails d'un objet PHP?

Question

Je travaille avec un objet qui retourne des informations dans un format comme le suivant ... J'ai supprimé certains détails où l'information devient un peu répétitive pour économiser de l'espace.

je besoin d'extraire des détails tels que ID, nom, etc. afin qu'il lit 4cff5974138c9, Mac Pro, etc., respectivement. Comment puis je faire ça?

Answer 1

Vous devez appeler une fonction de cette classe (dont ISC_QUOTE_ITEM est un objet - dire MyClass) qui retourne la variable protégée

Modifier
Il est accessible. J'avais raison

Vous aimez cette -

Ajoutez une fonction dans votre classe MyClass si vous ne possédez pas déjà un.

public function getName() 
{ 
    return $this->name; 
} 

Et puis dans votre code, vous pouvez le faire: -

echo $obj->getName(); 

Lire http://php.net/manual/en/language.oop5.visibility.php pour plus de détails sur la visibilité des types de variables

Answer 2

Vous pouvez le faire en utilisant la construction du réflecteur:

Exemple tiré de http://www.php.net/manual/en/reflectionclass.getproperties.php:

<?php 
class Foo { 
    public $foo = 1; 
    protected $bar = 2; 
    private $baz = 3; 
} 

$foo = new Foo(); 

$reflect = new ReflectionClass($foo); 
$props = $reflect->getProperties(ReflectionProperty::IS_PUBLIC | ReflectionProperty::IS_PROTECTED); 

foreach ($props as $prop) { 
    print $prop->getName() . "\n"; 
} 

var_dump($props); 

?> 

Comme vous pouvez le voir également le $bar protégé est retourné :) Et jetez un oeil à http://www.php.net/manual/en/reflectionproperty.getvalue.php#98643 là il est montré comment retourner la valeur d'un attribut protégé.
