Stumped by recurssion and array

[merc123]

I got a directory recurssion snippet off the net and need it to do something that I can't figure out.

 

It works correctly, but appears to make 2 seperate arrays.  Any way I can get them to be combined because I want to pick a random number and output a specific file.

 

It is looking in the directory ../gallery which also contains a subdirectory.  For each subdirectory it's creating a seperate array.  Any way to combine them or a different way to do this?

 

function getDirectory( $folder = '.', $level = 0 ){

// Space seperated list of extensions, you probably won't have to change this.
$exts = 'gif jpeg jpg png';
$ignore = array( 'cgi-bin', '.', '..' );        // Directories to ignore when listing output. Many hosts

$files = array(); $i = -1; // Initialize some variables
if ('' == $folder) $folder = './';

$handle = opendir($folder);
$exts = explode(' ', $exts);

      while (false !== ($file = readdir($handle))) {
        if( !in_array( $file, $ignore ) ){

         if( is_dir( "$folder/$file" ) ){
         // Its a directory, so we need to keep reading down...

             getDirectory( "$folder/$file", ($level+1) );
              // Re-call this same function but on a new directory.  This is what makes function recursive.

            }
            else {
            //If not a directory...

         foreach($exts as $ext) { // for each extension check the extension
           if (preg_match('/\.'.$ext.'$/i', $file, $test) && !eregi("thumb_",$file)) { // faster than ereg, case insensitive
           $files[] = $folder ."/". $file; // it's good
           ++$i;
     }
    }
   }
  }
}

echo "<pre>";
print_r($files_list);
echo "</pre>";

closedir($handle); // We're not using it anymore
}

getDirectory("../gallery");
