Php Ksort Help

[blakogre]

Thanks to all who've helped before: [a href=\"http://www.blakogre.com/epix/altdkp.php\" target=\"_blank\"]http://www.blakogre.com/epix/altdkp.php[/a] was the result. THANKS!
I've snipped the following code from a page which I've partially modified, but it's still not quite what I want: [a href=\"http://www.blakogre.com/guildviewer.php\" target=\"_blank\"]http://www.blakogre.com/guildviewer.php[/a]

[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]<tr>
<td><b>Name</b></td>
<td><b>Level</b></td>
<td><b>Rank</b></td>
<td><b>Note</b></td>
</tr>
OUTPUT;

ksort($classes); <-sorting by classes? This makes my major grouping?
foreach ($classes as $ckey => $class) { <-ckey -- that's defined here as teh $class variable
ksort($class); <- but... this sorts by class... so I'm not sure why there are 2. maybe created array? lost.

echo <<<OUTPUT
<tr>
<td colspan="4"><b>{$ckey}</b></td> <-- and this line is where ckey/class is inserted at each group
</tr>
OUTPUT;

foreach ($class as $member) {
$member['Name'] = htmlentities($member['Name']);
$member['Rank'] = htmlentities($member['Rank']);
$member['Note'] = htmlentities($member['Note']);
echo <<<OUTPUT
<tr>
<td>{$member['Name']}</td>
<td>{$member['Level']}</td>
<td>{$member['Rank']}</td>
<td>{$member['Note']}</td>
</tr>
OUTPUT;

}
}

echo <<<OUTPUT
</table>
OUTPUT;

?>[/quote]

Within each "Class" I want to sort by descending level as well: can I add another ksort in there? I've tried that, but I know my synatx is off, as I don't quite 100% understand what each line does. The pure HTML I get, it's the rest. I added my notes/what I think is going on. But again, I"m not a programmer, I come from an admin background.

Thx -- any help appreciated. My goals are simply for it to work, however, understanding it is great too. I love to learn by tweaking and playing and trying to get results I want.


So, it creates major class groupings, and then within that, ideally:

Sort by descending lvl
and within lvl
Sort by ascending name

Charles 60
Alan 55
Trudie 30
Jack 28

(The data is stored in another PHP page -- page one "parser.php" parses a text file, which creates page 2 "data.php", which feeds into this page, "viewer.php")

if the inforamtion is in a DB, use SQL DESC to have your array automatically sorted that way.

if you have the data in an array, do a numeric sort on the second element of the second dimension and reverse results. you may have to convert the value to an integer...

Well, I added:

OUTPUT;

[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]ksort($classes);
foreach ($classes as $ckey => $class) {
ksort($class);

echo <<<OUTPUT
<tr>
<td colspan="4"><b>{$ckey}</b></td>
</tr>
OUTPUT;
[b]sort($level);[/b]
foreach ($level as $member) {

[b]sort($level);[/b]
$member['Name'] = htmlentities($member['Name']);
$member['Rank'] = htmlentities($member['Rank']);
$member['Note'] = htmlentities($member['Note']);
echo <<<OUTPUT
<tr>
<td>{$member['Name']}</td>
<td>{$member['Level']}</td>
<td>{$member['Rank']}</td>
<td>{$member['Note']}</td>[/quote]

Of course, not working. I don't have 100% understanding or even close -- the "<--" comments in the first post are mine, trying to wrap my brain around it all.

The initial array:

[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]$classes = [b]array();[/b]

foreach ($guilddata['Members'] as $name => $info) {
if (empty($classes[$info['Class']])) {
$classes[$info['Class']] = array();
}
$classes[$info['Class']][$name] = $info;
}[/quote]

So -- I think in the () I need values I can reference for the sort? Tried putting things in -- got errors....

I also tried adding a line like krsort($members['Level'])

and got:
Warning: krsort() expects parameter 1 to be array, string given in C:\Inetpub\boc\guildviewer.php on line 137

added right before the last echo<<<output above (ditched the sort/$level stuff)
