Without setting the entire array directly, remove the element with the value "Green".

no longer passed. i dont know wat is wrong with my code.

index.php 
<?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";

array_pop($colors,  2,  1);

Hi Andres,

In last challenge, you are calling the wrong array function. 'array_pop()' removes the last item from the array, not an item at the specified index. Try 'array_splice()' instead:

<?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";

array_splice($colors,  2,  1);

And yes, as Andrew said, 'unset()' also does the trick. :)
