Get an array of class static member variables

Question

Example class:

class Example{
   public static $ONE = [1,'one'];
   public static $TWO = [2,'two'];
   public static $THREE = [3,'three'];

   public static function test(){

       // manually created array 
       $arr = [
           self::$ONE,
           self::$TWO,
           self::$THREE
       ];
   }       
}

Is there a way in PHP to get an array of class static member variables without creating it manually like in the example?

Answer 1

Yes there is:

Using Reflection, and the getStaticProperties() method

class Example{
   public static $ONE = [1,'one'];
   public static $TWO = [2,'two'];
   public static $THREE = [3,'three'];

   public static function test(){
        $reflection = new ReflectionClass(get_class()); 
        return $reflection->getStaticProperties();
    }       
}

var_dump(Example::test());
