[php] How do I get class name in PHP?

public class MyClass {

}

In Java, we can get class name with String className = MyClass.class.getSimpleName();

How to do this in PHP? I already know get_class(), but it works only for objects. Currently I work in Active Record. I need statement like MyClass::className.

It sounds like you answered your own question. get_class will get you the class name. It is procedural and maybe that is what is causing the confusion. Take a look at the php documentation for get_class

Here is their example:

 <?php

 class foo 
 {
     function name()
     {
         echo "My name is " , get_class($this) , "\n";
     }
 }

 // create an object
 $bar = new foo();

 // external call
 echo "Its name is " , get_class($bar) , "\n"; // It's name is foo

 // internal call
 $bar->name(); // My name is foo

To make it more like your example you could do something like:

 <?php

 class MyClass
 {
       public static function getClass()
       {
            return get_class();
       }
 }

Now you can do:

 $className = MyClass::getClass();

This is somewhat limited, however, because if my class is extended it will still return 'MyClass'. We can use get_called_class instead, which relies on Late Static Binding, a relatively new feature, and requires PHP >= 5.3.

<?php

class MyClass
{
    public static function getClass()
    {
        return get_called_class();
    }

    public static function getDefiningClass()
    {
        return get_class();
    }
}

class MyExtendedClass extends MyClass {}

$className = MyClass::getClass(); // 'MyClass'
$className = MyExtendedClass::getClass(); // 'MyExtendedClass'
$className = MyExtendedClass::getDefiningClass(); // 'MyClass'

To get class name you can use ReflectionClass

class MyClass {
    public function myNameIs(){
        return (new \ReflectionClass($this))->getShortName();
    }
}

It looks like ReflectionClass is a pretty productive option.

class MyClass {
    public function test() {
        // 'MyClass'
        return (new \ReflectionClass($this))->getShortName();
    }
}

Now, I have answer for my problem. Thanks to Brad for the link, I find the answer here. And thanks to J.Money for the idea. My solution:

<?php

class Model
{
    public static function getClassName() {
        return get_called_class();
    }
}

class Product extends Model {}

class User extends Model {}

echo Product::getClassName(); // "Product" 
echo User::getClassName(); // "User" 

This will return pure class name even when using namespace:

echo substr(strrchr(__CLASS__, "\\"), 1);    

end(preg_split("#(\\\\|\\/)#", Class_Name::class))

Class_Name::class: return the class with the namespace. So after you only need to create an array, then get the last value of the array.

I think it's important to mention little difference between 'self' and 'static' in PHP as 'best answer' uses 'static' which can give confusing result to some people.

<?php
class X {
    function getStatic() {
        // gets THIS class of instance of object
        // that extends class in which is definied function
        return static::class;
    }
    function getSelf() {
        // gets THIS class of class in which function is declared
        return self::class;
    }
}

class Y extends X {
}
class Z extends Y {
}

$x = new X();
$y = new Y();
$z = new Z();

echo 'X:' . $x->getStatic() . ', ' . $x->getSelf() . 
    ', Y: ' . $y->getStatic() . ', ' . $y->getSelf() . 
    ', Z: ' . $z->getStatic() . ', ' . $z->getSelf();

Results:

X: X, X
Y: Y, X
Z: Z, X

<?php
namespace CMS;
class Model {
  const _class = __CLASS__;
}

echo Model::_class; // will return 'CMS\Model'

for older than PHP 5.5

You can use __CLASS__ within a class to get the name.
