[PHP] mootoolsを使った slideshowで、ディレクトリ内のjpgを指定

randjpg関数を改変

function slideshowdata($tagdir = 'top')
{
  if ($dh = opendir($tagdir)) {
    for ($i = 0; $file = readdir($dh); ) {
      if (preg_match ('/.jpg$/', $file)) {
        $images[$i++] = $file;
      }
    }

    srand ((float)microtime() * 1000000);
    shuffle ($images);
    $cnt = $i;

    for ($i = 0; $i < $cnt; $i++) {
      if ($i) print ", ";
      print "\"{$images[$i]}\"";
    }

    closedir($dh);
  } else {
    print "directory open error\n";
  }
}
