In the last objective of Static functions, I dont know what should I pass in the static method?

Should I pass the $room->getDimensions()? How would it work while the static function is expecting an array $size). I dont get it. Please help.

index.php 
<?php

class Render {

   public static function displayDimensions($size) { 
   return $size[0]. " x ".  $size[1];
   }

  public static function detailsKitchen($room) {

    return "Kitchen Dimensions: ". Render::displayDimensions($room->getDimensions());
  }

}



?>

Hi Marwa Rashad,

When working with static types in PHP there is a special keyword called self which allows us to access the statically typed properties and methods of an class. In this case you would substitute Render:: with self::.

Happy coding!

Hello Chris! Thanks a lot. Still I have tried this and still not working:

class Render {

  public static function displayDimensions($size) {

    return $size[0]. ' x '. $size[1];

  }

  public static function detailsKitchen ($room) {

    return "Kitchen Dimensions: ". self::displayDimensions($room->getDimensions);

  }

}

?>
