sorting arrays in php - then back to Flash

[vman]

Hello everyone. I have a problem that I can't seem to solve. I have a completely dynamic imageviewer that creates a specific number of buttons based on how many folders are in a directory. I have php script that does this. I can't figure out how to arrange the array in alphabetical order before it is sent back to Flash. I ahve also tried sorting in Flash and have been unsuccessful. Here's is the script I have so far which is way off I know. Can someone give me a hand with this? Thanks.



<?
$dir = "Gigs";
$dh = opendir($dir);
while (false !== ($filename = readdir($dh))) {
if($filename != "." && $filename != "..") {
$foldernames=array($filename);

}
}
closedir($dh);

sort($foldernames);

foreach($foldernames as $val) {
echo "&foldernames=".$val;

}
?>


Here's a link to the image viewer:

You need a method of incrementing the array, and then add the filenames to the array after the increment. Try something like this:
<?
$dir = "Gigs";
$dh = opendir($dir);
$foldernames=array();
$filecounter=0;
while (false !== ($filename = readdir($dh))) {
if($filename != "." && $filename != "..") {
$filecounter++;
$foldernames[$filecounter]=$filename;

}
}
closedir($dh);

sort($foldernames);

foreach($foldernames as $val) {
echo "&foldernames=".$val;

}
?>

[vman]

Well,
I tried that but it returns:
&foldernames=01-12-04 TEST3&foldernames=01-22-04 TEST2&foldernames=04-17-04 TEST1&foldernames=TEST FOLDER 4&foldernames=TESTER1&foldernames=TESTER2&foldernames=TESTER3

I think I need something that returns:
&foldernames=01-12-04 TEST3, 01-22-04 TEST2, 04-17-04 TEST1, TEST FOLDER 4, TESTER1, TESTER2, TESTER3.

But it did sort them!

My php still sucks, otherwise I'd be able to take what you did and get what I need. I'll give it a shot in the AM.

Thanks for your help!

This should give you what you need:
<?
$dir = "Gigs";
$dh = opendir($dir);
$foldernames=array();
$filecounter=0;
while (false !== ($filename = readdir($dh))) {
if($filename != "." && $filename != "..") {
$filecounter++;
$foldernames[$filecounter]=$filename;

}
}
closedir($dh);

sort($foldernames);

echo "&foldernames=";
foreach($foldernames as $val) {
echo $val.", ";

}
?>
Happy Holidays! :)

Excellent! Thanks a lot. I appreciate it. Now all i have to do is reverse the order which I'm thinking should be fairly painless. I can probably do that in Flash.


Thanks again!

use rsort instead of sort... This sorts in reversed order

Well, I already did something different before I read this:

<?
$dir = "Gigs";
$dh = opendir($dir);
$foldernames=array();
$filecounter=0;
while (false !== ($filename = readdir($dh))) {
if($filename != "." && $filename != "..") {
$filecounter++;
$foldernames[$filecounter]=$filename;

}
}
closedir($dh);

sort($foldernames);
$foldernames = array_reverse($foldernames);

echo "&foldernames=";
foreach($foldernames as $val) {
echo $val.",";

}
But I think your way is probably a couple microseconds faster!
