从Android中的PHP文件中获取所有文件名

Question

Edit: For all those who are downvoting, this isn't the same question asked many times before. I'm NOT A PHP developer. I want to retrieve all the images names from a folder on my FTP server. I googled and found this script:

<?php
foreach (new DirectoryIterator(__DIR__) as $file) {
  if ($file->isFile()) {
      print $file->getFilename() . "
";
  }
}
?>

Since I'm not a PHP dev, I can't understand even a word of it.

What I Want: Modify PHP script so that it returns an array containing file names and want some android code which accepts the array.

Thank You!

Answer 1

I don't know who wrote that method, but PHP already has a built in method to return the contents of a directory http://php.net/manual/en/function.scandir.php

If you only want to include files and not folders with scandir, this answer will help Include JUST files in scandir array?
