Script to randomly display a file on a website?

Question

JavaScript

We need a script that would randomly display a file from a certain directory on the site.
Those. when visiting the site (or when reloading the page), each time a new file would be displayed, which would be randomly selected from a certain directory.
The file type can be: graphics, sound, video.
Are there ready-made solutions?

Answer 1

Only knowing the list of all files, otherwise nothing...

Answer 2

In php you can do something like this:

function randomFileFromDir($dir){
  $scan = array();
  $scan = scandir($dir);
  $files = array_diff($scan, array('.', '.'));
  return $scan[array_rand($scan)];
}
$randomFile = randomFileFromDir('someFolder');
$file_type = pathinfo($randomFile, PATHINFO_EXTENSION);

switch($type ){
case 'mp3';
  echo 'Тут вывод плеера';
break;
case 'jpg':
case 'png':
  echo 'Тут вывод картинки, если картинки , можно дополнить выборку выше';
break;
//...ну и так далее...

}

of course the code is not the first ideal xD

Answer 3

Let me add to the question:
let's say there is a directory "123", it contains files of different formats (jpg, mp3, mp4, well, etc.)
The script randomly selects, for example, jpg and it is necessary that this file be displayed on the site not just a filename. And, accordingly, if it is mp3 or mp4, then something like a player would be loaded so that you could immediately listen / view the file.
Here, I would like to find something ready in this regard ...
