Totally stuck

Hope you guys can see my code....

I tried different things but didn't came up with a solution... This task description seems a little vague in my opinion, maybe it's just because I speak dutch ...

index.php 
<?php
class Render {

    static function displayDimensions($size)
    {
      return $size[0] ." x ". $size[1];
    }
    static function detailsKitchen($room)
    {
      return "Kitchen Dimensions: " .$self::displayDimensions($room->getDimensions());
    }
    static function getDimensions()
    {
      return array(12,14);
    }

 $newRoom = new Render

$newroom->detailsKitchen($newroom);

}
?>

HI Wouter,

You should fix your code

  1. to display output , you should use "print_r" or "echo"
  2. closed bracket of class Render was misplaced
  3. you forgot ";" on new Render
  4. you don't need input for detailsKitchen, just call the function
  5. you can call function within the class by just using "$this->name_of_function"
  6. change all "static" to "public"

try this

class Render {

    public function displayDimensions($size)
    {
      return $size[0] ." x ". $size[1];
    }
    public function detailsKitchen()
    {
      return "Kitchen Dimensions: " .$this->displayDimensions($this->getDimensions());
    }
    public function getDimensions()
    {
      return array(12,14);
    }
}
$newRoom = new Render;
print_r($newRoom->detailsKitchen()); // display output
?>

Oups... I didn't realize this is a code challenge.... You should use "self::" instead of "$self::"

it becomes 

class Render {

    static function displayDimensions($size)
    {
      return $size[0] ." x ". $size[1];
    }
    static function detailsKitchen()
    {
      return "Kitchen Dimensions: " .self::displayDimensions(self::getDimensions());
    }
    static function getDimensions()
    {
      return array(12,14);
    }
}
$newRoom = new Render;

print_r($newRoom->detailsKitchen());

?>

Hope it helps
