Change the value of an array element

Don't know what they're asking for. Seems like this. Guess not.

index.php 
<?php

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

//add modifications below this line

array_unshift($colors, 'Yellow');
array_push($colors, 'Black');

$colors[0] = 'Magenta';
$colors[2] = 'Cyan';

Hi there! You're close! Remember, you added something to the beginning of the array. You added "Yellow" to the beginning and "Black" to the end. This means that "Red" is no longer at index 0, but rather at index 1. Yellow is the new value at index 0.

I think you can get it with these hints, but let me know if you're still stuck! :sparkles:
