PHP PHP Arrays and Control Structures PHP Arrays Modifying Arrays

I'm adding things to the array but its telling me I'm not.

I'm pretty sure I'm using the right code for adding objects to both the front and back of the array but when I tried to submit it, it proclaims that I ahve not added anything to the array

index.php 
<?php

$colors = array("Red","Green","Blue");

//add modifications below this line
array_unshift($color,'Yellow');
array_push($color,'Black');
?>

I was able to complete the challenge using double quotes on Yellow and Black. Not sure why, but I'm guessing it needs to follow the same format as the array you're modifying.

Perhaps someone with a bit more PHP knowledge can explain in more detail.

I don't think changing the quotes did anything to help pass the challenge.

While you were making that change, you probably also fixed the spelling of "$color" (as shown in this code) to "$colors" (which is the correct name).
