PHP: Is it possible to retrieve the class name of a child class?
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
}
}
How can I get the class name of Bob
from inside 开发者_StackOverflow中文版the constructor of the Person
class?
Use get_class($this).
It works for sub-class, sub-sub-class, the parent class, everything. Just try it! ;)
class Person
{
public function __construct()
{
echo get_class($this);
}
}
class Bob extends Person
{
//do some stuff
}
$b = new Bob;
prints Bob
as explained in "Example #2 Using get_class() in superclass" at http://docs.php.net/get_class
class Bob extends Person
{
//do some stuff
}
class Person
{
public function __construct()
{
var_dump(get_class($this)); // Bob
var_dump(get_class()); // Person
}
}
new Bob;

<?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();
