Static method quiz

Question

The following question is no getting solved and i might be doing something wrong, i might be of negative side of php as i can only understand the question as i solved it.

The accepted parameter $size will be an array containing length and width in that order. Add a return value to the displayDimensions method that returns these values as a string "length x width".

my code

class Render{
 public station function displayDimensions($size){
   $size = array(
    'length' => 12,
    'width' = 14
     return $size;
);
}
}

Hi, Ammar,

Imagine that the $size parameter already comes as an existent array. like this:

$size = array( 12,  14);
//The first element is the length and the second is the width.

So when you create the method and pass the parameter, you just need to return the length and the width of that parameter array. So how do you fetch an specific value, without even knowing its key? The step says that the first value is the length and the second, the width, so their keys are 0 and 1, in that order. You just ned to return these values, like this:

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

Also pay attention in the way you called your method, you called it "station", instead of "static". You also tried to return a value inside the array, which is not possible.
