22,110 PointsTesting out the answer choices for this question does not produce the desired results. rsort works, but not the others.
Question:
$colors = array("Red", "Orange", "Yellow", "Green", "Blue", "Purple", "Black");
Which function will sort the array so the first element is "Yellow"?
Options:
- sort
- asort
- krsort
- ksort
- arsort
<?php
$colors = array("Red", "Orange", "Yellow", "Green", "Blue", "Purple", "Black");
rsort($colors);
for ($index = 0; $index < count ($colors); $index ++) {
echo $colors[$index] . "\n";
}
//Yellow
//Red
//Purple
//Orange
//Green
//Blue
//Black
Everything else will produce other results not matching the desired output.
I've ran the code online using PHP Sandbox

This is an array with random colors: $colors = array("Red", "Orange", "Yellow", "Green", "Blue", "Purple", "Black");
Using the rsort function will sort the array in reverse alphabetical order.

22,110 PointsHi Bára Paulátová, your solution worked. I forgot the sorting method would not be noticeable unless I used a for each loop instead of a standard for loop.
Thanks to you and Cris Pijper!
