php - php 如何统计文件夹中的文件数

Question

此代码仅显示目录，但我想显示文件夹内包含计数文件的目录

示例 计算文件夹内的文件数

• 文件夹A(找到 2 个文件)
• 文件夹B(找到 19 个文件)
• FolderD(找到 1 个文件)

• FolderD(找到 13 个文件)

  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>';
    }
  ?>

这样的事情应该可以帮助你:

$count = iterator_count(new DirectoryIterator($path));

https://www.php.net/iterator_count

所以:

<?php
function folderlist(){
  $directoryist = 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"){
                       $directorylist[$startdir . $folder]['name'] = $folder;
                       $directorylist[$startdir . $folder]['path'] = $startdir;
                   }
               }
           }
           closedir($dh);
       }
   }
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;
?>
