PHP PHP Arrays and Control Structures PHP Arrays Modifying Arrays

Are we able to update the value in the array by using array_splice this method?

I did try two of the methods to actually resolve the problem I met in this challenge task 2 of 3. The first one I try is using array_splice method to actually replace the element with the specific index number and the value the questions given. The second method is just simple assign the array[number] to the new value. But both methods are not able to pass this challenge. Any help will be appreciate! Thanks!

index.php 
<?php

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


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

//Method 1
array_splice($colors,0,"Magenta");
array_splice($colors,2,"Cyan");

//Method 2
array["Red"] = "Magenta";
array["Blue"] = "Cyan";
?>

Hi WK h,

With array_splice you need the 3rd argument to be how many items you're removing which is 1 in this case. The 4th argument is the new color value. You also have to adjust your indices. "Red" is not at index 0 anymore and "Blue" is not at index 2

It's easier to do method 2 though but the index is integer based. You have to specify the integer index for "Red" and for "Blue" keeping in mind that "Yellow" was added to the beginning.
