arrays... and long-term-novice

Posted by Ja NE on 10/25/05 13:08

I need to sort some values by percentage, and don't know how...

here is where I got so far:

mysql_query("SELECT sum($usage)...
list($total)... // now I have total number I need to find %

mysql_query...
while(list($id,$usage) = mysql_fetch_array)) {
mysql_query("SELECT sum($usage) WHERE id=$id...
list($used)... // now I have some usage for each $id

$made = sprintf("%.f", $used / $total * 100);

echo"$id $made<br>"; //will output:

101 @ 50.38%
102 @ 25.19%
103 @ 24.43%

and I want to deal with the last only from this example. with the one of
smallest percentage and I can't know which one will that be.

I think I have to create and sort array, but whatever I have made, I had
no success.
if I create array inside of while{} I end with 3 different arrays.
if I end while {} I have only one to work with...

can anyone help me? (I have avoided arrays so far with "great" success,
but from now on, I just have to use them and I don't understood them at
all. my english isn't that good, and haven't find proper documentation
on my language to learn)

tnx in advance
