文件和目录的问题

PHP code

  $dirname = "paragraph";
  $dir_handle = opendir($dirname);
  while($file = readdir($dir_handle)){
  echo"<tr>";
  echo"<td>".date("Y年n月t日",filemtime($file))."</td>";
  echo"</tr>";
}

paragraph是根目录下文件夹

 SAE_Warning: filemtime() [function.filemtime]: stat failed for 001.txt in soulList.php on line 11
 
 SAE_Warning: filemtime() [function.filemtime]: open_basedir restriction in effect. File(..) is not within the allowed path(s): 

用的是SAE,文件路径有问题？

是的，文件路径有问题
echo"<td>".date("Y年n月t日",filemtime("$dirname/$file"))."</td>";
