4,471 PointsReturn the $size array as a string?
I don't understand what they want me to do. I tried it with return $size, but that returns the array itself. So i made a foreach loop and append it to a var named $output.. and then return $output.
<?php
class Render {
public static function displayDimensions($size){
return $size;
}
}
?>

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

4,471 PointsWho the heck makes such things separate? If you have a dimension, you prob make it something like ['10cm x 20cm','5cm x 10cm']. If you make it something like ['10cm','50cm','14cm'] those are not dimensions, just random values inside an array. I was expecting something like ['10cm x 20cm']... Either they fix these arrays or they show how the array looks like.
