file_put_contents error

my files in plugin resources folder:
arenas/default.yml

PHP:

if(!is_file($this->getDataFolder()."arenas/default.yml")){
                fopen($this->getDataFolder()."arenas/default.yml", "w");
                file_put_contents($this->getDataFolder()."arenas/default.yml", $this->getResource("arenas/default.yml"));
        }

Spoiler: error message

Code:

[CRITICAL] Could not save Config C:\Users\Honza\Documents\PocketMine-MP\plugins\ColorMatch/arenas/C:\Users\Honza\Documents\PocketMine-MP\plugins\ColorMatch/arenas/default.yml: file_put_contents(C:\Users\Honza\Documents\PocketMine-MP\plugins\ColorMatch/arenas/C:\Users\Honza\Documents\PocketMine-MP\plugins\ColorMatch/arenas/default.yml): failed to open stream: Invalid argument

thx

maybe problem was in this method:

PHP:

public function checkArenas(){
        $this->getLogger()->info("checking arena files...");
        foreach(glob($this->getDataFolder()."arenas/*.yml") as $file){
            $arena = new Config($file, Config::YAML);
            if($this->checkFile($arena)){
                $last = strrpos($file,'.')+1;
                $pripona = ($last > 1) ? substr($file, $last) : false;
                $this->setArenasData($arena, $pripona);
                $this->getLogger()->info("$file checking sucessful");
            }
            else{
                $this->getLogger()->critical("$file is not setup properly");
                return;
            }
        }
    }

i used

PHP:

new Config($this->getDataFolder()."arenas/".$file, Config::YAML);

Try

PHP:

new Config($this->getDataFolder()."arenas/".$file, Config::YAML);

No it already works. I only forgot write "." here xD

That's what I posted xD

It is pointless to call fopen() if you don't use the return value as a stream to write/read to the file with.
