Add Players into a .yml

Hey Guys.....There is a "game.yml"...It looks like that:

Code:

---
gamemembers: ""
...

So..There I want that my Plugin write all PlayerNames of some choosen Players!

PHP:

$this->game = new Config($this->getDataFolder()."Locations/game.yml", Config::YAML);
$this->game->set("gamemembers", "$player1,$player2");

So here I add two Names of different Players! But what must I write, if I want to add a NEW Player? Because if I write it like that the old Players will delete and only the NEW Player will be stand there! So maybe something with a +?
Thanks Marcelo234

maybe

PHP:

$this->game->set("gamemembers", $this->game->get("gamemembers"), $player3);


And why is it so

Code:

"$player1,$player2"

and not so

Code:

$player1,$player2

?

You are using some bad practise but here is what you have to do then
Foreach new player

PHP:

NewPlayer = "BLA";
OldPlayers = Config::get("gamemembers");
Config::set("gamemembers", OldPlayers . NewPlayer);


Lol, we posted at the same time

@Tim // robske Büba [Du bist doch auch deutsch oder] But all ways are rigth {I think} xD

This isn't Java.

Forum = English only, still. And well, it's bad to save all of them into a config, but here:

PHP:

$this->game = new Config($this->getDataFolder()."Locations/game.yml", Config::YAML);
$old = $this->game->get("gamemembers");
$a = explode(",", $old);
array_push($a, $newPlayer);
$new = implode(",", $a);
$this->game->set("gamemembers", $new);
$this->game->save();

PHP:

function addMemberToConfig(Config $config, array $memberNames){
  $config->set("gamemembers", array_merge($memberNames, $config->get("gamemembers", [])));
}

So now.. Thanks....but how to delete a choosen player? And how to Test if the Playername is written there....

JavaScript*

So anyone can tell me how to remove a player from list and how to Check is the Playername is in the Config?
Thanks Marcelo234

To check: strpos(). To remove: explode(), then unset(), then implode()

Why is this java? I used static codes because you cannot assume that $this has config used!

What..? using . instead of -> is Java, not using $ on variables is java, and missing ;

Yay... Java... I like Java...

Edited my post a bit
And with . I meant the string glue
