How do I get class name in PHP?

Solution 1:

Since PHP 5.5 you can use class name resolution via ClassName::class.

See new features of PHP5.5.

<?php

namespace Name\Space;

class ClassName {}

echo ClassName::class;

?>

If you want to use this feature in your class method use static::class:

<?php

namespace Name\Space;

class ClassName {
   /**
    * @return string
    */
   public function getNameOfClass()
   {
      return static::class;
   }
}

$obj = new ClassName();
echo $obj->getNameOfClass();

?>

For older versions of PHP, you can use get_class().

Solution 2:

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

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'

Solution 4:

To get class name you can use ReflectionClass

class MyClass {
    public function myNameIs(){
        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"
