如何按时间对文件夹进行排序示例我在目录中创建最后/最新文件夹，以便最后一个文件夹显示在顶部。

这里是仅显示目录的代码

<?php

function folderlist(){
  $startdir = './';
  $ignoredDirectory[] = '.'; 
  $ignoredDirectory[] = '..';
   if (is_dir($startdir)){
       if ($dh = opendir($startdir)){
           while (($folder = readdir($dh)) !== false){
               if (!(array_search($folder,$ignoredDirectory) > -1)){
                 if (filetype($startdir . $folder) == "dir"){
                       $directorylist[$startdir . $folder]['name'] = $folder;
                       $directorylist[$startdir . $folder]['path'] = $startdir;
                   }
               }
           }
           closedir($dh);
       }
   }
return($directorylist);
}


$folders = folderlist();
    foreach ($folders as $folder){
    $path = $folder['path'];
    $name = $folder['name'];

echo '<li><a href="' .$path .'index.php?album=' .$name . '" class="style1"><font face="Tahoma" class="ws10"><B>' . $name . '</B></a><br /></li>';
  }
?>

为此，您需要首先获取文件夹的创建时间，并将其添加为数组项的键的开头，然后您将能够根据键进行排序...像这样的东西

<?php
function folderlist(){
  $directorylist = array();
  $startdir = './';
  $ignoredDirectory[] = '.';
  $ignoredDirectory[] = '..';
   if (is_dir($startdir)){
       if ($dh = opendir($startdir)){
           while (($folder = readdir($dh)) !== false){
               if (!(array_search($folder,$ignoredDirectory) > -1)){
                 if (filetype($startdir . $folder) == "dir"){
                       $created = filectime($startdir . $folder);
                       $directorylist[$created . $startdir . $folder]['name'] = $folder;
                       $directorylist[$created . $startdir . $folder]['path'] = $startdir;
                   }
               }
           }
           closedir($dh);
       }
   }

  ksort($directorylist);
  return($directorylist);
}


$folders = folderlist();

$total_files = 0;
foreach ($folders as $folder){
    $path = $folder['path'];
    $name = $folder['name'];
    $count = iterator_count(new DirectoryIterator($path . $name));
    $total_files += $count;

    echo '<li>';
    echo '<a href="' .$path .'index.php?album=' .$name . '" class="style1">';
    echo '<strong>' . $name . '</strong>';
    echo ' (' . $count . ' files found)';
    echo '</a>';
    echo '</li>';
}
  echo "Total Files:". $total_files;
?>

请注意正在使用的新$ created变量，以及用于按键对数组进行排序的ksort（）方法。

你可以按照相反的顺序排序krsort。

您还可以使用filemtime（）而不是filectime（）来更改基于修改日期的排序
