PHP array from files

[wiilweer]

Hello,

 

I'd like to make an array preferably multidimensional from files what are in subdirectory. Here is a code what I wrote but I doesn't work well becouse I wanted to load that string into javascript array..but it didnt work becouse it had some special characters..

 

$dir = opendir('f');
if($dir)
{
   $result = "";
   while (($file = readdir($dir)) !== false )
   {
      if(strpbrk($file, 'mp3'))
      {
         $result = $result ."{ Track name: \"$file\", location: \"f/$file\" },<br/>";
      }
   }
   echo $result;
   
}

I had similar problem some weeks ago, this should work for you

<?php
function add_dir_data($dir) {
  global $result;
  $d = dir($dir);
  while (false !== ($entry = $d->read())) {
    if ($entry === '.' || $entry === '..') { continue; }
    if (is_dir($entry)) { add_dir_data($entry); }
    elseif (strtolower(substr($entry, -4)) === '.mp3') {
      $result[] = array('track_name'=>utf8_encode(substr($entry, 0, -4)),'location'=>utf8_encode($d->path.'/'.$entry));
    }
  }
  $d->close();
}
$result = array();
add_dir_data('f');
?>
<script type="text/javascript">
var list = <?php echo json_encode($result); ?>;
</script>

 

If you have an outdated version of php(less than 5.2) you probably won't have json_encode, so maybe you can try function __json_encode listed on comments @ http://php.net/manual/en/function.json-encode.php
