PHP 包括文件夹中的随机文件

Question

I would like to use a <?php include... command to choose one random php file from one folder.

So this is the basic idea:

 <?php include 'random file: 1.php, 2.php, 3.php or 4.php';?>

I have already read articles like this or this , but they don't answer my question clearly. What is the easiest way to do that?

Answer 1

// Directory to use
$directory = '.';

// Filter out directories, we only want files.
$files = array_filter(scandir($directory), fn($f) => is_file($f));

// Pick a random file
$randFile = $directory . '/' . $files[array_rand($files)];

// Include it
include $randFile;

Answer 2

to include random files from another directory

  $path = __DIR__."/folder";
 
  foreach(new DirectoryIterator($path) as $file){
      if($file->isFile()){
        $arr[] = $file->getFilename();
      }
  }
  $randFile = $path."/".$arr[array_rand($arr)];

  include $randFile;
