Easiest way to get list of files in the server directory

问题

I need to get array of all images (or simply of all files) in directory (e.g. www.example.com/images/). I prefer to use JavaScript but it's hard to make. So should I use PHP, meybe?

Could you please help me - I'm not good at this.

Thank you very much!

回答1:

Javascript cannot fetch all files on a server, as it is a client-side langugage.

http://php.net/manual/en/function.glob.php is what you need.

$all = glob('/path/to/dir/*.*');

$images = glob('/path/to/dir/*.{jpg,png,gif}');

I disagree with @mariobgr. If there is no server setting preventing a directory listing, then the html generated by requesting that directory can be parsed for the contents.

$ tree maindir
maindir
├── index.html
└── somedir
    ├── doc1
    ├── doc2
    └── doc3

index.html

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <meta content="IE=edge,chrome=1" http-equiv="X-UA-Compatible"><!--  JQUERY  -->

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js">
  </script>
  <title></title>
</head>
<body>
  <h1>Listing /somedir</h1><!-- Custom Script (defered load, after dom ready) -->
  <script>
    $.get('http://localhost/maindir/somedir', (data) => 
    {
        console.log(data);
        let listing = parseDirectoryListing(data);
        $('body').append(JSON.stringify(listing));
    });

    function parseDirectoryListing(text) 
    {
        let docs = text
                     .match(/href="([\w]+)/g) // pull out the hrefs
                     .map((x) => x.replace('href="', '')); // clean up
        console.log(docs);
        return docs;
    }   
  </script>
</body>

Visiting localhost/maindir produces:

Listing /somedir
["doc1","doc2","doc3"]
