Pretty late in September to be doing your first homework assignment, isn't
it? Anyway that 'Array[3]' is nonsense and causes me to suspect that you
did not enter the array properly.

What do you get when you print_r($Differences)?

if you don't get

Array
(
[Brass] => 601.88
[Iron] => 376.18
[Steel] => 526.65
)

you have not entered the array you thought you did.

Yes, that would work, if your array is properly entered, but as we said in
the old country "Garbage in, garbage out."

You do know arsort gives you descending order. If you want ascending order,
use asort.

Here's your answer. Trying going to class once in a while.

#!/usr/local/bin/php
<?php

$Differences = array(
Brass => 601.88,
Iron => 376.18,
Steel => 526.65);

print_r($Differences);

/* Array
(
[Brass] => 601.88
[Iron] => 376.18
[Steel] => 526.65
)
is what you get here.
*/



arsort($Differences,SORT_NUMERIC);

print_r($Differences);

/* Array
(
[Brass] => 601.88
[Steel] => 526.65
[Iron] => 376.18
)
is what you get here. Of course there is no reading your mind, and if
you meant a different array or should have used asort, I cannot know that
at this end.
