Question

Can any one please let me know how to read the directory and find what are the files and directories inside that directory.

I’ve tried with checking the directories by using the is_dir() function as follows

$main = "path to the directory";//Directory which is having some files and one directory
readDir($main);

function readDir($main) {
    $dirHandle = opendir($main);
    while ($file = readdir($dirHandle)) {
        if ($file != "." && $file != "..") {
            if (is_dir($file)) {
                 //nothing is coming here
            }
        }
    }
}

But it is not checking the directories.

Thanks

The most easy way in PHP 5 is with RecursiveDirectoryIterator and RecursiveIteratorIterator:

$dir = '/path/to/dir';
$directoryIterator = new RecursiveDirectoryIterator($dir);

$iterator = new RecursiveIteratorIterator($directoryIterator, RecursiveIteratorIterator::CHILD_FIRST);

foreach ($iterator as $path) {
  if ($path->isDir()) {
     // ...
  }
}

You don’t need to recurse by yourself as these fine iterators handle it by themselves.

For more information about these powerful iterators see the linked documentation articles.
