How do I replace several values from array?

Got stuck with this task 1) How do I remove several values from a certain key from an array?

For example in this code I have 5 keys and I need to replace 2nd and 4th, so I assume I should use array_splice function: array_splice ($colors, 2, 4, array("magenta", "cyan")); But this seems to be wrong

index.php 
<?php

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

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

I think what they're testing you on is that the array reindexes. So if you add to beginning, the subsequent value indices adjust by one. For task 2, it accepts:

<?php

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

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

$colors[1] = "Magenta"; // red was previously was at position 0
$colors[3] = "Cyan";
