Scan multiple image directories in PHP

Question

Im trying to scan multiple image directories using PHP and create an array that contains the exact path of each image and its name.

Example directory tree

main/
├─ sub-directory-1/
│  ├─ image1.png
│  ├─ image2.jpeg
│  ├─ image3.png
├─ sub-directory-2/
│  ├─ image1.png
├─ sub-directory-3/
│  ├─ image1.jpeg
│  ├─ imageX.png

Example of desired array

{
    0 : {name: "image1", path: "main/subdirectory-1/image1.png"},
    1 : {name: "image2", path: "main/subdirectory-1/image2.jpeg"},
    2 : {name: "image3", path: "main/subdirectory-1/image3.png"},
    .
    .
    .
    7 : {name: "imageX", path: "main/subdirectory-3/imageX.png"},
}

This is the approach that got me the desired result.

I hope this will help someone

public function ImageScanner() {
    $current_dir = getcwd();
    $folderpath = 'PATH/TO/SOME/DIR/';

    // Determining if the path is a directory or not
    if (is_dir($folderpath)) {

        // Opening the directory
        $files = opendir($folderpath); {

            // Checking if the directory opened
            if ($files) {

                //Reading each element's name in the directory
                while (($subfolder = readdir($files)) !== false) {

                    // Checking for errors in filename
                    if ($subfolder != '.' && $subfolder != '..') {
                        $dirpath = 'SOME/SUB_DIR/PATH/' . $subfolder . '/';

                        // Checking and opening each file inside the sub directory
                        if (is_dir($dirpath)) {
                            $file = opendir($dirpath);
                            if ($file) {
                                
                                // Reading each element's name in the sub directory
                                while (($filename = readdir($file)) !== false) {
                                    if ($filename != '.' && $filename != '..') {
                                        $image_path = '' . $dirpath . '' . $filename . '';

                                        // Creating array for each scanned file
                                        $key = array(
                                            'image_name' => trim($filename) ,
                                            'image_path' => str_replace('/SOME/PATH/', '', $image_path) ,
                                        );

                                        // Appending each image array
                                        $image_arrays[] = $key;
                                    }
                                }
                            }
                        }
                    }
                }
            }
        }
    }
    return $image_arrays;
}
