How to connect another config?

Hi! I create plugin of passport for rp server, but i dont know how i can connect and give data in another plugin?

Khm... Sorry of my English

 

I took the PurePerms plugin as an example, in the plugin from which I need to pull the data, I wrote this

PHP:

public function getGroup($p){
    $name = $p->getName();
      $och = $this->ocho->getAll();
      $dir = $this->getServer()->getDataPath();
      $content = file_get_contents($dir."plugins/RichardRadioStation/point_radio.json");
      $data = json_decode($content, true);
    if(isset($ocho[$name])){
      $this->ocho->get($name, $data["$name"]);
    }
  }

after that, in the plugin that should accept this data, I made the following

PHP:

if($this->Eco->myMoney($p) >= 1000){
                  if($this->GI->getGroup($p) >= 5){
                        $this->Eco->reduceMoney($p, 1000);
                        $this->rich->set($p->getName(), 1);
                        $this->rich->save();
                        $p->sendMessage("§l§b» §fGreat job, your work is Police!");
                    } else {
                        $p->sendMessage("§l§b» §сYou havent need exp!");
                    }
                        } else {
                              $p->sendMessage("§l§b» §сyou havent money!");
                        }

But it not work, why?

 

PHP:

$this->GI->getGroup($p) // this call doesn't return a value, you can't do comparison with void value


 

thanks!\
