I use this code for read the directory of my photo in the rotator:
<?
// search for mp3 files. set this to '.flv' or '.jpg' for the other scripts
$filter = ".jpg";
// path to the directory you want to scan
$directory = "public/photo";


// read through the directory and filter files to an array
@$d = dir($directory);
if ($d) {
while($entry=$d->read()) {
$ps = strpos(strtolower($entry), $filter);
if (!($ps === false)) {
$items[] = $entry;
}
}
$d->close();
sort($items);
}

// third, the playlist is built in an xspf format
// we'll first add an xml header and the opening tags ..
header("content-type:text/xml;charset=utf-8");

echo "<playlist version='1' xmlns='http://xspf.org/ns/0/'>\n";
echo " <title>Sample PHP Generated Playlist</title>\n";
echo " <info>http://www.jeroenwijering.com/</info>\n";
echo " <trackList>\n";

// .. then we loop through the mysql array ..
for($i=0; $i<sizeof($items); $i++) {
echo " <track>\n";
echo " <title>".$items[$i]."</title>\n";
echo " <location>xxx</location>\n";
echo " </track>\n";
}

// .. and last we add the closing tags
echo " </trackList>\n";
echo "</playlist>\n";

?>


this code work correctly, but does not read files in the sub folders...
My folder photo($directory = "public/photo";), contains other 30 folders, how can read the files in subfolders for them to the playlist?

Tanks for the answer, but I have PHP Version 4.3.0

Whit your code have this error: Fatal error: Cannot instantiate non-existent class: recursivedirectoryiterator in /home/8034033890/www/web/v2/read33.php on line 11
You have a solution for me?

Tanks AJAX, i have tried your code... work correctly!
But, have a little problem: the playlist generated container a duble item

Example:
<?xml version='1.0' encoding='UTF-8'?>
<playlist version='1' xmlns='http://xspf.org/ns/0/'>
<title>Sample PHP Generated Playlist</title>
<info>http://www.jeroenwijering.com/</info>
<trackList>
<track>
<title>Photo-1</title>
<location>Photo-1.jpg</location>
</track>
<track>
<title>Photo-1</title>
<location>MyFolder/Photo/Photo-1.jpg</location>
</track>
</trackList>
</playlist>

<location>Photo-1.jpg</location> and <location>MyFolder/Photo/Photo-1.jpg</location> is a same image!
why?

Mar. 05, 2008AJAX

Find this code:            $directory_tree[] = array('path' => $path,
                                      'name' => end($subdirectories),
                                      'extension' => $extension,
                                      'size' => filesize($path),
                                      'kind' => 'file');and replace it with this code:            $directory_tree[] = array('path' => $path);

read the mp3 file from directory php5 but 3 warnings occur fread.fseek,fclose supplied arguments not valid

kindly give me any sollution

Ok.. heres a problem for me!!!

I used to have a playlist where i speciefied the folder it was going to look for .jpg. I had an array for the filename and then put that together with an array that gave the http url of that folder. Meaning the actual info that the player used to get the files from became the actual http url.

Now i want the playlist to look through all the subdirs for my gallery instead of me specifying one. So... i use the script above for PHP5 wich works fine.. it generates a playlist and so on... BUT.. the jeroenwijering doesnt seem to find the images now. I look at the location generated and it doesnt show the full http URL byt only the path from my root.

Heres an example of how the current tracks are generated in the playlist:

- <track>
<title>DSC04113</title>
<location>./gallery/g2data/albums/01/DSC04113.jpg</location>
<info>http://www.harleyotooles.com/gallery.php</info>
</track>

I have tried to move the imagerotator AND the playlist to the root. But still it doesnt seem to find the images. So.. how do i fix this? Either i need a way for the player to find the picture from that location info... OR i need to add some code in order for the playlist to actual generate the full http URL path. I tried to make an array for the website url and tried to add it before $item. But im a beginner at this and can only generate an address like this:

www.domain.com/./gallery/g2data/albums/albumdir/filename.jpg

So.. how do i work this one out?
Excuse me if i dont explain so good because i am new to this.. but i hope you understand.

Try this one. Adjust $url as necessary to get teh correct path(s).
<?php

// *** requires PHP5 ***

// search for jpg files
$filter = ".jpg";

// url to be added to the path *** NO TRAILING SLASH ***
$url = 'http://my.domain.com/path';

// path to the directory you want to scan
$directory = './';

$it = new RecursiveDirectoryIterator("$directory");

foreach(new RecursiveIteratorIterator($it) as $file)
{
  if (!((strpos(strtolower($file), $filter)) === false))
  {
    $items[] = preg_replace(array("#\\\#", "#./#"), array("/", "/"), $file);
  }
}
sort($items);

header("content-type:text/xml;charset=utf-8");

print <<<END
<?xml version='1.0' encoding='UTF-8'?>
<playlist version='1' xmlns='http://xspf.org/ns/0/'>
  <title>Sample PHP Generated Playlist</title>
  <info>http://www.mydomain.com/</info>
  <trackList>

END;

foreach($items as $item)
{
  $title_array = explode('/', $item);
  $title = substr(end($title_array), 0, (strlen(end($title_array)) - 4));
  print <<<END
    <track>
      <title>$title</title>
      <location>$url$item</location>
      <info>http://www.harleyotooles.com/gallery.php</info>
    </track>

END;
}

print <<<END
  </trackList>
</playlist>

END;

?>


I added your info element hard-coded, change it in the heredoc print block if you want something else.
