PHP: Est-il possible de récupérer le nom de classe d'une classe enfant?

Question

class Bob extends Person 
{ 
    //do some stuff 
} 

class Person 
{ 
    public function __construct() 
    { 
     //get the class name of the class that is extending this one 
     //should be Bob 
    } 
} 

Comment puis-je obtenir le nom de la classe de Bob à l'intérieur du constructeur de la classe Person?

Answer 1

Utilisez get_class ($ this).

Cela fonctionne pour la sous-classe, sous-sous-classe, la classe parente, tout. Essayez-le! ;)

Answer 2

<?php 

class Bob extends Person 
{ 

    public function __construct() 
    { 
     parent::__construct(); 
    } 

    public function whoAmI() 
    { 
     echo "Hi! I'm ".__CLASS__.", and my parent is named " , get_parent_class($this) , ".\n"; 
    } 
} 

class Person 
{ 
    public function __construct() 
    { 
     echo "Hello. My name is ".__CLASS__.", and I have a child named " , get_class($this) , ".\n"; 
    } 
} 

// Hello. My name is Person, and I have a child named Bob. 
$b = new Bob; 
// Hi! I'm Bob, and my parent is named Person. 
$b->whoAmI(); 

Answer 3

class Person 
{ 
    public function __construct() 
    { 
    echo get_class($this); 
    } 
} 

class Bob extends Person 
{ 
    //do some stuff 
} 

$b = new Bob; 

imprime Bob comme expliqué dans "Exemple # 2 Utilisation get_class() dans superclasse" à http://docs.php.net/get_class

Answer 4

class Bob extends Person 
{ 
    //do some stuff 
} 

class Person 
{ 
    public function __construct() 
    { 
     var_dump(get_class($this)); // Bob 
     var_dump(get_class());  // Person 
    } 
} 

new Bob;
