Hey. I found out the problem. It took me a minute because I did the same thing as you. I assumed that by "passing an array containing length and width" it meant an object with a key:value pair but it does not.

My php is a bit rusty so forgive my syntax if its a little off. The answer is solid, I tested it. :)

In case you dont know the difference... An array contains just values. Basically you can set $size = array(1, 2, "your momma"). Note - some languages allow you to include objects as values here but lets ignore this as to not cause confusion. An object has a key:value pair setup. Basically, you can set $size = array("length" => 1, "width"=> 2, "my honey"=>"your momma") .

So...the following works because its searching an array, rather than an object. Also, I think yours is using a capital "x" instead of a lowercase "x."

<?php

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

  }

}

?>

Also, I think my terminology is off. object = associative array...maybe. Idc....its all the same, just different languages with a more confusing way to say the same thing. :p

that worked. Thanks for the explanation!!
