Converting arrays into a multi-dimensional array

[LTMH38]

I have a list of folder names like 1, 2, 3... Each folder has some .jpg files.

I get a list of all including files from this directories with two glob functions dynamically.

I store a list of directory paths and filenames into two separates arrays called $DIR[] and  $files[].

How can I convert this arrays to one multidimensional array and how can I get values in each dimension with this array?

 

<?php
        //FOLDERS
        //create array for each directory
        $pathDIR = "dirname/";
        $DIR = Array(
        );
        //store directory names into an array with foreach
        foreach (glob($pathDIR . '/[0-30]*', GLOB_ONLYDIR) as $dirname) {
            $DIR[] = $dirname;    
        }
        //display path directories
        for($a = 0; $a < count($DIR); $a++) {
            echo $DIR[$a] . "<br>";   
        }
        //FILES
        //create array for each directory
        $pathFILE = Array();
        //create array for files    
        $files = Array();            
        //loop start
        for($b = 1; $b <= count($DIR); $b++) {
            $pathFILE[$b] = "dirname/" . $b . "/"; 
            //store files in array with foreach
            foreach(glob($pathFILE[$b] . '*.jpg') as $filename) {
                $files[] = $filename;
            }
        }
        //display files
        for($c = 1; $c <= count($files); $c++) {
            echo $files[$c-1] . "<br>";
        }
        //convert arrays to multidimensional array 
        array_push ($DIR, $files);         
        ?>

Well, what do you want the format of this multi-dimensional array to be? I typically use something like this

'folder1name' => array(
    'files' = array(list of files in folder1name),
    'folders' = array(
        'subfolder1name' =>array(
            'files' => array(list of files in folder1name),
            'folders'  = array(
                //Same format if there are more subfolders
            )
        ),
        'subfolder2name' =>array(
            'files' => array(list of files in folder1name),
            'folders'  = array(
                //Same format if there are more subfolders
            )
        )
    )
)

Use a recursive function EG

$dir='path/to/folder';

$results = [];
getFiles($dir, $results);
    // show results
echo '<pre>', print_r($results, 1), '</pre>';


function getFiles($dir, &$results)
{
    $d = dir($dir);
    while (false !== ($entry = $d->read())) {
       if ($entry=='.' || $entry=='..') continue;
       if (is_dir($dir.'/'.$entry)) {
           getFiles($dir."/$entry", $results['folders'][$entry]);
       }
       else $results['files'][] = $entry;
    }
    $d->close();
}

Thank Psycho and Barand.

I had tried with array_push:

array_push ($DIR, $file); 

to display array values I had tried with a pair of loops:

 for($d = 0; $d <= count($DIR); $d++) {
            for($e = 0; $e <= count($DIR[$d]); $e++) {
                echo $DIR[$d][$e] . "<br>";
            }
        }

Unfortunately array values are not properly show. Also, a notice indicate undefined offset .
