Image gallery without database

This image gallery was developed using only PHP in the beckend, it is not necessary to use a database. As for the frontend, it was developed using only HTML, CSS and JavaScript.

1. how is it possible not to use DB?

This is possible thanks to the FilesystemIterator class, this class is native to PHP and it returns a list of files and folders that are inside the directory informed in its constructor. Note: this instance of FilesystemIterator, as its name suggests, is iterable as an array, that is, it can be used directly in a repetition structure such as for (), foreach () and etc.. See the example:

<?php
$files = new FilesystemIterator(
    __DIR__.'/public/assets/img'
);
foreach($files as $file){
    echo $file
        ->getFilename().PHP_EOL;
}

The above code will print:

top_directory.png
