Converting to array

hi all, i’m not much of a php guru, so here’s my question
i have created a very basic script which shows the content of a certain directory like so

if ($myDir = opendir('.')) {
  
    while (false !== ($file = readdir($myDir))) {
        if ($file != "." && $file != "..") {
            echo "$file<br />
";
            
        }
    }
    closedir($myDir);
}

and now the silly and probably noobish question: how can i convert the list of contents from the directory to an array?

thanks
