PHP mini application to present downloadable files

Einblick

My first real PHP application consists in just one page that looks for files in a specific folder on a web server and presents them as download links in a nicely styled table. For this quick solution I used a FTP connection to upload and manage the the content of the download folder.

The looks

I owe credits to Gunta Klavina, who designed the table CSS. I downloaded it from the CSS Table Gallery.

The script

The script is very simple. It goes to a specified directory and lists all files that are in there. Then it gets file size and last modified time from each of the files and adds them to an html table.

  foreach($files as $file)
  {
  	  if($file != "." && $file != "..")
  	  {
  	  	$name = basename($file);
        $file = $dir.$file;
        $date = date('j F Y H:i', filemtime($file));
        $size = filesize($file).' bytes';

  	  	echo '<tr '; echo ($odd % 2)? 'class="odd">' : '>';
  	  	echo '<th scope="row">'.$name.'</th>';
  	  	echo '<td>'.$size.'</td>';
  	  	echo '<td>'.$date.'</td>';
		echo '<td>Here is room for a detailed content description.</td>';
		echo '<td><a href="'.$file.'" title="Download the '.$name.'">Download</a></td>';
		echo '</tr>';'
		$odd++;
