title: php delete a single file in directory
body: <p>I've got the php list directory script from this link <a href="http://www.gaijin.at/en/scrphpfilelist.php">http://www.gaijin.at/en/scrphpfilelist.php</a>.
  How do I delete a single file from the directoy? I tried <code>unlink</code>, but it deleted all the files from that directory. this the short code what i got from the link!</p>
  
  <pre><code>while ($file = readdir ($hDir)) {
  if ( ($file != '.') &amp;&amp; ($file != '..') &amp;&amp; (substr($file, 0, 1) != '.') &amp;&amp;
       (strtolower($file) != strtolower(substr($DescFile, -(strlen($file))))) &amp;&amp;
       (!IsFileExcluded($Directory.'/'.$file))
     ) {
  
    array_push($FilesArray, array('FileName' =&gt; $file,
                                  'IsDir' =&gt; is_dir($Directory.'/'.$file),
                                  'FileSize' =&gt; filesize($Directory.'/'.$file),
                                  'FileTime' =&gt; filemtime($Directory.'/'.$file)
                                  ));
  }
  }
  $BaseDir = '../_cron/backup';
  $Directory = $BaseDir;
  
  foreach($FilesArray as $file) {
    $FileLink = $Directory.'/'.$file['FileName'];
    if ($OpenFileInNewTab) $LinkTarget = ' target="_blank"'; else $LinkTarget = '';
      echo '&lt;a href="'.$FileLink.'"&gt;'.$FileName.'&lt;/a&gt;';
      echo '&lt;a href="'.unlink($FileLink).'"&gt;&lt;img src="images/icons/delete.gif"&gt;&lt;/a&gt;&lt;/td&gt;';
    }
  }
