PHP PHP Arrays and Control Structures PHP Arrays Modifying Arrays

Adding element to beginning of array . . . what's wrong with array_unshift in this task?

Am doing the task in PHP Arrays and Control Structures where you have to add "Yellow" to the beginning and "Black" to the end of the array $colors. I'm doing the following:

$colors = array_unshift($colors, "Yellow");

It's telling me "Bummer! Add "Yellow" to the BEGINNING of the array"

Am I missing something?

index.php 
<?php

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

//add modifications below this line
$colors = array_unshift($colors, "Yellow");
$colors = array_push($colors, "Black");

The Array functions take an array as a first parameter so we don't have to use $colors = before them. They are self-enclosed and modify the array within the function so they don't return an array.

tl;dr: Remove $colors = from the array_* function calls.
