As William has said, but the short syntax for creating an array using just [] is from PHP 5.4 and the 'original' way of creating an array is

$colors = array();

Notice the parenthesis (curved brackets), not square brackets (which are what are used in the new shorthand array creation without the word array) - you are basically mixing the two variations of how to create an array and it appears that the challenge will accept either version.

Thanks Emma for the more detailed explanation on the array creation syntax :)

Hi, there, there're some problems here.

  • don't forget to put a ; at the end of this line $bool=true
  • the variable name is colors, not color.
  • the right syntax to use for array creation is $colors=[];
<?php

//Place your code below this comment
$integer_one=1;
$integer_two=2;
$golden=1.618;
$bool=true;

$colors=[];
?>
