How to remove (PHP)

If you want to delete a directory using PHP,  first you need to delete all existing files inside it.

For these purposes, you can use this function:

public function removeDirectory($dir): bool

{

    $files = array_diff(scandir($dir), array('.', '..'));

    foreach ($files as $file) {

        (is_dir("$dir/$file")) ? $this->removeDirectory("$dir/$file") : unlink("$dir/$file");

    }

    return rmdir($dir);

}
