php loops directory

我需要创建一个遍历子目录中所有文件的循环。你能帮我这样构建我的代码吗：

$main = "MainDirectory";
loop through sub-directories {
    loop through filels in each sub-directory {
        do something with each file
    }
};

将 RecursiveDirectoryIterator 与 RecursiveIteratorIterator 结合使用。

$di = new RecursiveDirectoryIterator('path/to/directory');
foreach (new RecursiveIteratorIterator($di) as $filename => $file) {
    echo $filename . ' - ' . $file->getSize() . ' bytes <br/>';
}

您需要将路径添加到递归调用中。

function readDirs($path){
  $dirHandle = opendir($path);
  while($item = readdir($dirHandle)) {
    $newPath = $path."/".$item;
    if(is_dir($newPath) && $item != '.' && $item != '..') {
       echo "Found Folder $newPath<br>";
       readDirs($newPath);
    }
    else{
      echo '&nbsp;&nbsp;Found File or .-dir '.$item.'<br>';
    }
  }
}

$path =  "/";
echo "$path<br>";

readDirs($path);
