Controll Practice

Hey Guys..I want to test some things! So there is a Folder and in this folder a few files are! The files name can't be anything! IMPORTANT: The Files name will change their name every few minutes! Some Files could be remove or create with a new random name!! So In every File there is a Random thing....(All the files are in "Random/")
For Example(here 3 files!):
File1:

Code:

Random: "a"

File2:

Code:

Random: "z"

File3:

Code:

Random: "e"

So now the Plugin should get all Files at same time...He should cgeck...For Example: If the Random: ""
== e a Event will happen....
My ask is: => How I get all the Random Files?

PHP:

$files = new config($this->getDataFolder() . "Random/", Config::YAML, array());

And than check?

Foreach the files.

Soorrrrryy,don't understand correctly..

Do you know foreach? If not, google it.
Simply foreach the files in your directory:

PHP:

$files = scandir($this->getDataFolder()."Random/");
foreach($files as $file) {
  // Do something
}

Use glob() with the asterisk or the RecursiveDirectoryIterator, though better use glob.
