Command not working and not showing any errors

I have this code:

PHP:

    public function onCommand(CommandSender $player, Command $command, $label, array $args) : bool{
        switch ($command->getName()) {
            case "sg":

                        if($args[0]=="make")
                        {
                            if(!empty($args[1]))
                            {
                                if(file_exists($this->getServer()->getDataPath() . "/worlds/" . $args[1]))

                                    $player->teleport($this->getServer()->getLevelByName($args[1])->getSafeSpawn(),0,0);
                                }
                                else

                }
                else

                }
            }
        }
        return true;
    }
    

The first command works perfectly fine (/sg make) but the second command (/sg join) does not work. why is this.
btw the second command is not finished, there are still more things I must add but as it is now it's not working and not showing any errors when the command in ran

 

What is the error?

 

you somehow attempted to create /make and not /sg make
here's it fixed:

PHP:

<?php

   switch($command->getName()){

            switch($args[0]){
               case "make":
                  if($player->isOp()){
                     if(!empty($args[1])){
                        if(file_exists($this->getServer()->getDataPath() . "/worlds/" . $args[1])){
                           $this->getServer()->loadLevel($args[1]);
                           $this->getServer()->getLevelByName($args[1])->loadChunk($this->getServer()->getLevelByName($args[1])->getSafeSpawn()->getFloorX(), $this->getServer()->getLevelByName($args[1])->getSafeSpawn()->getFloorZ());
                           array_push($this->arenas, $args[1]);
