Object Oriented PHP Static challenge 2 of 4

Question

I am doing this challenge and an error message comes up: Bummer! You must return the dimensions using the $size parameter.
I thought I was doing that any help is appreciated!
```index.php
<?php class Render {
  public static function displayDimensions($size)
  {
    $size = array("length", "width");
   return $size;
  }
}
?>
```

Hi there!  The $size is a parameter which means it's an array being sent by another piece of code.  That array contains two numbers.  The first one is the length and the second is the width.  You've taken the information they've sent in and overwritten it with an array that contains two strings "length" and "width".   Then you return that array.  But they are looking for you to return a string that contains the length and the width they sent in.  For example, if they send in an array that looks like [10.2, 15.3], they want a string returned that says "10.2 x 15.3".  This is how I did it:
```php
<?php class Render {
  public static function displayDimensions($size) {
    return "$size[0] x $size[1]";
  }
}
?>
```
This declares a function that accepts an array containing two numbers which represent the length and width.  We can access the array elements using subscripting and expand them inside the string using the double quotation marks and then return the resulting string.
Hope this helps! :sparkles:
