PHP - Sorting

Greetings!

I would like to ask for you help sorting a couple of lists that are autogenerated with php.
The page reads a content of a folder and makes a menu from the names. The folder names a a, b, c, d... etc.

The other part reads the content of the selected folder and displays the files.

My problem is, that on windows, using xampp, the both the folders and files appear in alphabetic order (what I want), but on the linux server they get completely messed up.
Instead of a, b, its o, a, d, etc.
I tried using the sort() function but there is no array to sort...

Thank you for any suggestions and help!

ps. the server has php 4.3.9... does this matter? could help if we upgrade to 5.3?

here is the code:
Code: [Select]
<?php     
     $dh  = opendir($dir);

     while (false !== ($filename = readdir($dh))) {

       $files[] = $filename;

        if ($filename != "." && $filename != "..")
                     {    
        if($_SERVER['REQUEST_URI'] == "index.php?l=" . $filename . '&sec=' . $sec){
                     echo '<td><img src="imagini/arow.gif"></td><td style="text-align: left;">' . strtoupper($filename) . $space;
                     } else {    

            echo '<td style="text-align: left;"><a href="index.php?l='. $filename . '&sec=' . $sec . '">' . strtoupper($filename) . $space;                }}}

?>

<?php

    $letter = "a";

    if(isset($_GET["l"])){

    $letter = $_GET["l"];} 

    $letter = $dir . $letter;

 if ($handle = opendir($letter)) {

   while (false !== ($file = readdir($handle)))

      {

          if ($file != "." && $file != "..")

      {

     $filename = $file;
     $file2 = substr($filename, 0, -4);
     $thelist .= '<tr><td style="width: 250px; text-align: left;"><a href="'. $letter . '/'. $file.'">'.$file2.'</a></td></tr>';

          }
       }
  closedir($handle);
  }
?>
<p><?php echo $thelist; ?></p>

Hi - I'm modifying some PHP code that someone else wrote. Below is a snippet of code that basically takes mp3 files files within all the folders in a directory, and creates an RSS feed. In the resulting feed, the files are intermingled in date order.

Instead, I'd like them sorted by the directory that they are in. So, if there are files in these directories:

01-First
02-Second
03-Third

I'd like all the files in the "01-First" directory to come before the "02-Second" directory and so on. Within each directory the files can be sorted as they currently are.  The name of the directory in the code is signified by $dir_name.

I tried sort() and array_multisort() but I couldn't get either of them to work the way I wanted.  Any thoughts?


if ($url_params['mode'] == 'rss2') {

print getRSSHeader('UTF-8', $device, $vm_config, $vm_name, $web_master, $logo_image,$context);
    $mailboxes = array();
if ($dev_dir = @opendir($VMHome . $device)) { //might fail if mailbox has not received first message yet
while ($f = readdir($dev_dir)) {
     if (!eregi("tmp","$f") && !eregi("\.+","$f") && !eregi("Exclude-From-CD", "$f")) { //skip tmp directory and Exclude-From-CD Directories   
     array_push($mailboxes,"$f"); #collect all existing mailboxes
     }
  }
     array_multisort($mailboxes, SORT_DESC);
foreach ($mailboxes as $mailbox) {
$files=array();
$dir_name = $VMHome . $device . '/'. $mailbox .'/'; 
$dir = opendir($dir_name);
while ($f = readdir($dir)) {
  if (eregi("\.txt",$f)){ #if filename matches .txt in the name
     array_push($files,"$f"); #push into $files array
  }
}
foreach($files as $file){
   $props = getProperties($dir_name, $file);
   $uid = getMP3File($dir_name, $file, $props, $device, $mailbox, $vm_config, $vm_name,$context);
   print getRSSItem ($props, $uid, $dir_name, $device, '/' . $mailbox . '/', $context);      
}
}
}
print  '

Hi! I am absolute noob in php, but need to create descending sorting by last modified/date. How I could achieve this? Many thanks for help!

I am using the following code to sort by Year. It displays the current year fine and current year also displays in selection but does give the option for the previous years selection.

Code: [Select]
<form action="archivednews.php" method="post">
<select name="year" id="year">
<?PHP for($i=date("Y");
$i<=date("Y");
$i++)  
if($year == $i)
echo "<option value='$i' selected>$i</option>";
else
echo "<option value='$i'>$i</option>";
?>
</select>
<input type="submit" value="GO">
</form>

I am looking for information on how to accomplish this:

I want to order an array based on a variable. I have an array that is set like this array(1,2,3,4,5,6).
I want to order this array base on a variable that will be in the array.
So say my variable $x = 3, I want to order the array starting with the number right after the $x. So the array would look like this now array(4,5,6,1,2,3). Is this even possible?
Another example if $x = 6, The array would be array(1,2,3,4,5,6). So basically order the array so that the set variable (in this case $x) will be at the end and the rest will run in order.

I have the following php array structure and couldnot able to sort it according to the overall points. My code is reading an xml file using simplexml. Any help would be appreciated.

Array

            [overallpoints] => 0
        )

            [won] => 3
            [drawn] => 0

I am trying to populate this from a database list the results come ordered like this

4.2
4.3
4.4
4.5
4.6
5.0
6.0
where the "." show the 1st childs and the "-" show the 2nd child

I tried to do this by splting each line and determining if it is a zero or not if it was a zero i put that paticular one into an array to be used in the sub menu however this did not work out. Any ideas?

I have an array that looks like this...

Code: [Select]
Array (
    [0] => Array ( [0] => 2 [1] => Dylan Cross )
    [1] => Array ( [0] => 5 [1] => Bob Smith )
    [2] => Array ( [0] => 1 [1] => Sarah Park )
    [3] => Array ( [0] => 7 [1] => Jane Knowles )
    [4] => Array ( [0] => 6 [1] => Harry Hill )
    [5] => Array ( [0] => 3 [1] => Jack Rock )
)

How do I sort this array so it is ordered alphabetically by the names so the result will be...

Code: [Select]
Array (
    [0] => Array ( [0] => 5 [1] => Bob Smith )
    [1] => Array ( [0] => 2 [1] => Dylan Cross )
    [2] => Array ( [0] => 6 [1] => Harry Hill )
    [3] => Array ( [0] => 3 [1] => Jack Rock )
    [4] => Array ( [0] => 7 [1] => Jane Knowles )
    [5] => Array ( [0] => 1 [1] => Sarah Park )
)
