How can I classifiy alphabetically using opendir ?

Hello

I have the following code
$path = "/home/seoplatf/cache/directory/";
$r= opendir($path);                              
while ($fichier = readdir($r)){
 if (strpos($fichier,".")>0) {
            $dossier=substr($fichier,strpos($fichier,".")+1);
            $filename=substr($fichier,0,strpos($fichier,"."));                  
            }            
        }              
 closedir($r);

How can I modify this code in order to classifiy alphabetically $filename?

Thanks

regards

You could store the filenames in an array, then sort the array.

code:

<?php
$path = "./";
$r= opendir($path);
$numfiles=0;
while ($fichier = readdir($r)){
 if (strpos($fichier,".")>0) {
            $dossier=substr($fichier,strpos($fichier,".")+1);
            $filename[$numfiles]=substr($fichier,0,strpos($fichier,"."));
            $numfiles++;
            }
 }

echo "<h1>Before Sort</h1>";
for($i=0;$i<$numfiles;$i++){
 echo "<li>[$i] ".$filename[$i]."</li>";
 }

// Sort the array
sort($filename);

echo "<h1>After sort</h1>";
for($i=0;$i<$numfiles;$i++){
 echo "<li>[$i] ".$filename[$i]."</li>";
 }

 closedir($r);
 ?>

It might be that the php5 directoryiterator has your files sorted by default. It would require a testrun though:

<?php
$dir = new DirectoryIterator("./");
foreach ($dir as $file) {
    if ($dir->isDot()) {
        continue;
    }
    echo $file . "\n";
}
?>

What does opendir() sort by as a default????

From: http://us3.php.net/manual/en/function.readdir.php
"The filenames are returned in the order in which they are stored by the filesystem."

A method of sorting:

if ($handle = opendir('audio')) {
 while (false !== ($file = readdir($handle))) {
  if ($file != "." && $file != "..") $thefiles[] = $file;
 }
 closedir($handle);
}

sort($thefiles);

for ($i=0;$i<count($thefiles);$i++) {
echo '&file'.($i+1).'='.$thefiles[$i];
}

echo "&total=$i";

I have done

            $numfiles++;
            }
 }
// Sort the array
sort($filename);
 closedir($r);
but I would like to sort also $dossier because $filename[$numfiles] must correspond to $dossier$numfiles]. HNow can I do?

Thanks

you are trying to split the extension. if you want to split the extenstion. split this after doing the the sort. After splitting you can have the sorted array and form a single loop and split the extension in another array and use where ever you want.
