如何使用目录从PHP获取标题 - php

Question

Fairly new to php, so bear with me. I'm trying to figure out how to read a directory/folder and return both the filename/path and the title of that file into a li.

$handle = opendir('.'); 
while (false !== ($file = readdir($handle))){ 
  $extension = strtolower(substr(strrchr($filename, '.'), 1)); 
  if($extension == 'html' || $extension == 'htm' || $extension == 'php'){ 
      echo "<a href='".$filename."'><li class='"iso_block"'><span>"**Title Tag Here**"</span></li></a>";
  } 
}

^code from miro(cheers/thanks)

$handle = opendir('.');
$dom    = new DOMDocument();

while (false !== ($file = readdir($handle))){ 
    $extension = strtolower(substr(strrchr($file, '.'), 1));
    if ($extension == 'html' || $extension == 'htm' || $extension == 'php') {
        $title = 'Untitled Document';

        if($dom->loadHTMLFile($urlpage)) {
            $list = $dom->getElementsByTagName("title");
            if ($list->length > 0) {
                $title = $list->item(0)->textContent;
            }
        }

        echo "<a href='$filename'><li class='iso_block'><span>$title</span></li></a>";
    } 
}
