Replacement syntax.

Elements are being replaced and passed om to the next element. Any Suggestions

index.php 
<?php

$colors = array("Red","Green","Blue");
array_unshift($colors,"Yellow");
array_push($colors,"Black");
//add modifications below this line
$colors [0]= "Magenta";
$colors [2]= "Cyan";

var_dump($colors);

Hi Shubham,

There are a couple of problems. You need to remove the space between the array index and the value like so. Otherwise the code doesn't know you're trying to change the value.

<?php
$colors[1]= "Magenta";
$colors[2]= "Cyan";

Secondly you need to take into account that you've added new values to the array with push and unshift.

So try to imagine that you have 5 indexes in the array and not just the 3 and give the correct indexes in your answer. :-)

Good luck!
