Using the RecursiveDirectoryIterator [duplicate]

Displaying folders and making links of those folders

I'm trying to create a simple file browser using the RecursiveDirectoryIterator but can't seem to figure it out... Any help please?

$cwd = '/path/to/somewhere';
if(isset($_GET['path']) && is_dir($cwd.$_GET['path'])) {
    $cwd .= $_GET['path'];
}

$dir = new RecursiveDirectoryIterator($cwd);
$iter = new RecursiveIteratorIterator($dir, RecursiveIteratorIterator::SELF_FIRST);
while($iter->valid()) {
    // skip unwanted directories
    if(!$iter->isDot()) {
        if($iter->isDir()) {
            // output linked directory along with the number of files contained within
            // for example: some_folder (13)
        } else {
            // output direct link to file
        }
    }
    $iter->next();
}

Not sure if this is the best approach, but I'm under the impression that the RecursiveDirectoryIterator is faster than both the opendir() and glob() methods.

SELF_FIRST and CHILD_FIRST as nothing to do with RecursiveDirectoryIterator but RecursiveIteratorIterator

If you run

$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir), RecursiveIteratorIterator::SELF_FIRST );

foreach ( $iterator as $path ) {
    if ($path->isDir()) {
        print($path->__toString() . PHP_EOL);
    } else {
        print($path->__toString() . PHP_EOL);
    }

You would get

...\htdocs\lab\stockoverflow\css
...\htdocs\lab\stockoverflow\css\a.css
...\htdocs\lab\stockoverflow\css\b.css
...\htdocs\lab\stockoverflow\css\c.css
...\htdocs\lab\stockoverflow\css\css.php
...\htdocs\lab\stockoverflow\css\css.run.php

If you change it to RecursiveIteratorIterator::CHILD_FIRST

...\htdocs\lab\stockoverflow\css\a.css
...\htdocs\lab\stockoverflow\css\b.css
...\htdocs\lab\stockoverflow\css\c.css
...\htdocs\lab\stockoverflow\css\css.php
...\htdocs\lab\stockoverflow\css\css.run.php
...\htdocs\lab\stockoverflow\css

Can you see the difference is in the position of the current folder
