Generate playlist using php and getid3

New to php.

I use a php script to generate a playlist, the first song entry in the list is blank for all fields (artist, title, length, filename). Why?

Her开发者_如何学Pythone's the script

 <?php

 require_once('getid3/getid3.php');

 $dir = 'mp3';
 $file_type = 'mp3';

 $play_list = '<?xml version="1.0" encoding="utf-8"?><config>';


 if (is_dir($dir)) {

 if ($dh = opendir($dir)) {

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

 if ($file != '.' && $file != '..') {

 $name_array = explode('.', $file);


 if ($name_array[1] == $file_type) {

 $play_list .= '<song>';

 $file = "$dir/$file";

 $getID3 = new getID3;

   $ThisFileInfo = $getID3->analyze($file);

  getid3_lib::CopyTagsToComments($ThisFileInfo);


         $play_list .= '<artist>'.$ThisFileInfo['comments_html']['artist'][0] . '</artist>';

         $play_list .= '<title>'. $ThisFileInfo['tags']['id3v2']['title'][0]. '</title>';

  $new_playtime = ereg_replace("[^A-Za-z0-9]", "", $ThisFileInfo['playtime_string'] );

  $play_list .= '<length>'.$new_playtime . '</length>';
  $play_list .= '<fileName>'.$file.'</fileName>';



 $play_list .= '</song>';

 }

 }

 }

 closedir($dh);

 $play_list .= '</config>';

 echo "$play_list";

 }

 }


     ?>

And here's how the ouput looks.

     <?xml version="1.0" encoding="utf-8"?>
    <config>

     <song><artist></artist><title></title><length></length><fileName>mp3/air - all i need.mp3</fileName></song>

<song><artist>Air</artist><title>Remember</title><length>234</length><fileName>mp3/air - remember.mp3</fileName></song>

<song><artist>Air</artist><title>You Make It Easy</title><length>401</length><fileName>mp3/air - you make it easy.mp3</fileName></song>

<song><artist>Ian Brown</artist><title>Dolphins Were Monkeys (Single Version)</title><length>258</length><fileName>mp3/Ian Brown - Dolphins Were Monkeys.mp3</fileName></song>

<song><artist>Ian Brown</artist><title>F.E.A.R.</title><length>431</length><fileName>mp3/Ian Brown - Fear.mp3</fileName></song>

<song><artist>Ian Brown</artist><title>Keep What Ya Got</title><length>348</length><fileName>mp3/Ian Brown - Keep What Ya Got.mp3</fileName></song>

<song><artist>Ian Brown</artist><title>My Star</title><length>509</length><fileName>mp3/Ian Brown - My Star.mp3</fileName></song>

<song><artist>Ian Brown</artist><title>Time Is My Everything</title><length>354</length><fileName>mp3/Ian Brown - Solarized - 02 - Time Is My Everything.mp3</fileName></song></config>      

The filename field isn't empty : <song><artist></artist><title></title><length></length><fileName>mp3/air - all i need.mp3</fileName></song>

Maybe it's just because the ID3 tags aren't set for "all i need.mp3" ?

P.S : you should use pathinfo with PATHINFO_EXTENSION instead of an explode, because if a song contains several dots it won't be matched.

Try using glob() to get the files. http://us.php.net/manual/en/function.glob.php

$files = glob($dir . '/*.mp3');

foreach ($files as $file) {
...
}

Use pathinfo() to get the file extension information. http://php.net/manual/en/function.pathinfo.php

Although, if you use the glob() function above, you wouldn't have to, since the *.mp3 will already filter the mp3 files.
