PHP的读取目录和输出日期修改为文件夹

Question

我有一个工作代码，读取一个目录并已输出name,total files和size。我想要做的也是抓住Date Modified并将其格式化为YYYY-MM-DD。

代码：

if ($handle = opendir('D:/'.$sub.'/')) { 

    while (false !== ($entry = readdir($handle))) { 
     if ($entry != '$RECYCLE.BIN' && $entry != 'System Volume Information' && $entry != '.' && $entry != '..') { 
     $exists = mysql_query('SELECT * FROM comics WHERE arc LIKE "'.$entry.'%"'); 
     $exists1 = mysql_num_rows($exists); 
      if ($exists1 == 0) { 
      $directory = $base.$sub."/".$entry; 
      $filecount = count(glob($directory."/"."*.*")); 
      $size = 0; 
      $d = new RecursiveIteratorIterator( 
      new RecursiveDirectoryIterator($directory), 
      RecursiveIteratorIterator::SELF_FIRST 
      ); 

      foreach($d as $file){ 
      $size += $file->getSize(); 
      } 

      $entry = str_replace(" - ", ": ", $entry); 
       mysql_query('INSERT INTO comics (arc, files, size) VALUES ("'.$entry.'\n", "'.$filecount.'", "'.$size.'")'); 
       print "<li>Inserted <b>".$entry."</b> With A File Count Of <b>".$filecount."</b> & A Total Size Of <b>".$size."</b> Bytes.</li>"; 
      } 
     } 
    } 
}

if (file_exists($filename)) { 
    echo "$filename was last modified: " . date ("Y-m-d", filemtime($filename)); 
}
