Achieving desired output, but can't pass challenge!!!

I have tried this in a variety of ways and can display the array dims accordingly. However, I am denied passing the challenge and am issued error msgs such as "The displayDimensions method should return the values of the size array" or given a reminder that the array is 0 indexed.

In my opinion, this objective is worded in a terribly ambiguous manner. Do they want me to create a $size array myself? Am I to call the displayDimension method myself? Or, should I just write the return output for the method? I am frustrated as I have spent an hour and a half on a two minute objective.

I have shown in my below code multiple ways I have attempted this. Please someone kindly advise.

index.php 
<?php

class Render {

public static function displayDimensions($size) {

  $output = "";   
  $output = $size[0] ." X ". $size[1];
  return $output;    
  }
}
//above code produces output of "12 x 14"
class Render {

  public static function displayDimensions($size) {

    $output = "";
    $output = implode(" X ", $size);
    return $output;
  }
}
//above code produces output of "12 X 14"

$size = [12, 14];
echo Render::displayDimensions($size);
//I have tried this challenge both with and without creating the $size array and calling the function myself
?>

For the first part of the challenge, you're doing too much work. Simply return a concatenated version of the array.

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

Then later you'll go on to use the displayDimensions method in another function. When you get there, pay attention to the fact that the $room object you're being provided in the background has a getter method to use in order to access its private properties
