hope you are after the last challenge, where to remove the element green, as I see the first and the second challenge, are correct. do you want to do some search on unset with using the index to remove

This is how the final code should look:

<?php

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

//add modifications below this line
array_unshift($colors, "Yellow");
array_push($colors, "Black");
$colors[1] = "Magenta";
$colors[3] = "Cyan";
unset($colors[2]);

Also don't forget to run 

var_dump($colors)

trough the preview so you can see how the array looks
