Using an array to sort a list of numbers

[LanceT]

Alright so I'm using PHP to generate a number of scores.

After the score is calculated (my script does this), I have a variable called "score."

I'm generating several of these scores and I want to sort them from highest to lowest and then print them out highest to lowest. I'm guessing I would use a PHP array and then use the sort method.

Anyone have some syntax of how I would do this?

rsort($array);

I also need some help on declaring an array and then inserting each value into the aray. Thanks.

[LanceT]

looking some more it looks like I can just do this right

$Array[]=$score;

Will it add on to the end of the array when i do
$Array[]=$score;

again?

Also which way of rsort would I need to sort them in numerical value order?

see the manual. [url=http://www.php.net/manual/en/language.types.array.php]array()[/url] and [url=http://php.net/rsort]rsort()[/url].

sort() will sort ascending, rsort will sort descending, which is apparently what you want. And, yes, you can just use $Array[] = $score to have the $score added to the array as a new item.

[code]<?php
$scores = 12;
$scores = 8;
$scores = 3;
$scores = 22;
$scores = 19;
$scores = 5;

rsort($scores);
print_r(scores);
?>[/code]

mjdamato you missed the [] on your $scores variable.

[code]
<?php
$scores[] = 12;
$scores[] = 8;
$scores[] = 3;
$scores[] = 22;
$scores[] = 19;
$scores[] = 5;

rsort($scores);
print_r($scores);
?>
[/code]
