PHP recursive folder scan into multi array (subfolders and files)

Question

I'm a little bit lost here at the moment. My goal is to recursive scan a folder with subfolders and images in each subfolder, to get it into a multidimensional array and then to be able to parse each subfolder with its containing images.

I have the following starting code which is basically scanning each subfolders containing files and just lost to get it into a multi array now.

$dir = 'data/uploads/farbmuster';
$results = array();

if(is_dir($dir)) {
    $iterator = new RecursiveDirectoryIterator($dir);

    foreach(new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::CHILD_FIRST) as $file) {
        if($file->isFile()) {
            $thispath = str_replace('\\','/',$file->getPath());
            $thisfile = utf8_encode($file->getFilename());

            $results[] = 'path: ' . $thispath. ',  filename: ' . $thisfile;
        }
    }
}

Can someone help me with this?

Thanks in advance!

You can try

$dir = 'test/';
$results = array();
if (is_dir($dir)) {
    $iterator = new RecursiveDirectoryIterator($dir);
    foreach ( new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::CHILD_FIRST) as $file ) {
        if ($file->isFile()) {
            $thispath = str_replace('\\', '/', $file);
            $thisfile = utf8_encode($file->getFilename());
            $results = array_merge_recursive($results, pathToArray($thispath));
        }
    }
}
echo "<pre>";
print_r($results);

Output

Array
(
    [test] => Array
        (
            [css] => Array
                (
                    [0] => a.css
                    [1] => b.css
                    [2] => c.css
                    [3] => css.php
                    [4] => css.run.php
                )

            [CSV] => Array
                (
                    [0] => abc.csv
                )

            [image] => Array
                (
                    [0] => a.jpg
                    [1] => ab.jpg
                    [2] => a_rgb_0.jpg
                    [3] => a_rgb_1.jpg
                    [4] => a_rgb_2.jpg
                    [5] => f.jpg
                )

            [img] => Array
                (
                    [users] => Array
                        (
                            [0] => a.jpg
                            [1] => a_rgb_0.jpg
                        )

                )

        )

Function Used

function pathToArray($path , $separator = '/') {
    if (($pos = strpos($path, $separator)) === false) {
        return array($path);
    }
    return array(substr($path, 0, $pos) => pathToArray(substr($path, $pos + 1)));
