如何使用PHP获取目录名（非子目录）和文件名？

Question

I have following folder structure. I want to get names of only directories (NOT subdirectories) and files . How can I do that with PHP? Thank you.

Main Directory
 Directory1
  SubDirectory1
   File1
   File2
  SubDirectory2
   File3
   File4
 Directory2
  SubDirectory3
   File5
   File6
  SubDirectory4
   File7
   File8

Result should be something like that:

Directory: Directory1
File: File1
File: File2

Directory: Directory2
File: File3
File: File4

Answer 1

Try DirectoryIterator,here is an example

$path = dirname(dirname(__FILE__));
$it = new DirectoryIterator($path);
while($it->valid()){
    /*....*/
    echo $it->getPathname().'">'.$it->getBasename();
    $it->next();//i forgot this just now
}

Answer 2

function display_directory($path){
    $dir_handle = @opendir($path) or die("unable to open $path");
    while ($file = readdir($dir_handle)){
      if($file == "." || $file == "..")
        continue;
      if(is_dir($file))
        echo "directory: $file";
      else
        echo "file: $file";
    }
}
