[PHP] gli elementi dell'array non vengono inseriti in ordine!

ciao raga,

come da topic,

questo è lo script.

<?php

function dir_book($path_book){ 
    $fd_book = opendir($path_book); 
    while($file_book = readdir($fd_book)){ 
        if($file_book != '.' && $file_book != '..'){ 
            $ris_book[count($ris_book)]['name'] = $path_book."/".$file_book; 
            if(is_dir($ris_book[count($ris_book)-1]['name'])){ 
               $ris_book = array_merge($ris_book, dir_book($path_book."/".$file_book)); 
            }                 
        } 
    } 
    closedir($fd_book); 
    return $ris_book; 
} 
$dir_book = dir_book("./book/".$_GET['t']);
foreach ($dir_book as $super_book => $valore_book) 
    foreach ($valore_book as $chiave_book => $value_book) 
         $string_book .="<page>$value_book</page>\n"; 
      $string_book .= "</pages>\n</FlippingBook>\n";
?>

mi stampa una cosa

- <pages>
  <page>03.jpg</page> 
  <page>05.jpg</page> 
  <page>04.jpg</page> 
  <page>01.jpg</page> 
  <page>02.jpg</page> 
  </pages>

io invece voglio che vengano stampati in ordine alfabetico... ovvero

- <pages>
  <page>01.jpg</page> 
  <page>02.jpg</page> 
  <page>03.jpg</page> 
  <page>04.jpg</page> 
  <page>05.jpg</page> 
  </pages>

grazie

forse ho risolto con questo script:

<?php
function trierdossier($dirname, $sortby, $sortdir) {

$ext = array("jpg", "png", "jpeg", "gif", "pdf", "doc", "txt", "xls");
$files = array();
   if($handle = opendir($dirname)) {
       while(false !== ($file = readdir($handle))){
           for($i=0;$i<sizeof($ext);$i++){
               if(stristr($file, ".".$ext[$i])){ //NOT case sensitive: OK with JpeG, JPG, ecc.
                   $filesize = filesize($dirname . "/" . $file);
                   $date3 = explode("_-_",$file);
                   $date2 = explode(".pdf",$date3[1]);
                   $date1 = $date2[0];
                   
                   if($filesize){
                       $files[] = array(
                                       "name" => $file
                                       //"size" => $filesize,
                                       //"date" => $date0
                                 );
                   }
               }
           }
       }
   closedir($handle);
   }
 
   //obtain an array of columns
   foreach ($files as $key => $row) {
       $name[$key]  = $row['name'];
       $size[$key] = $row['size'];
       $date[$key] = $row['date'];
   }
 
return array_multisort($$sortby, $sortdir, $files) ? $files : false;
}
//end
?>

<?php
//affichage
$sortby = "date"; // sort-by column; accepted values: name OR width OR height OR size
$path = './book/Marco e Chiara'; // path to folder
$sortdir = SORT_DESC; // sorting order flags; accepted values: SORT_ASC or SORT_DESC
$files = trierdossier($path, $sortby, $sortdir);
foreach ($files as $file){

echo $file['name'];
echo $file['date'];
echo $file['size'];

}
?>
