Reload a map

Hello,
I am working on a skywars plugin, I need at the end of the game to replace the map by a new one. I tried to use copy() but apparently it's only for files.
Thank you for your help.

I found :

Code:

 $zip->open($this->getServer()->getDataPath()."zipworld/worldName.".zip");
            $zip->extractTo($this->getServer()->getDataPath()."worlds/".$worldName."/");
            $zip->close();

In the main folder (with "players", "worlds"...) create a folder name zipworlds and put a zip version of the world.
Then just replace with the worldName. The only problem is I can't unload world (crash..) if you can help : http://forums.pocketmine.net/threads/level-unload-cause-crash.7407/

Thanks

Using ZIP is actually not performance optimized. Try referring to the file functions in the LegionPE plugin here:
