PHP:

public function onCommand(CommandSender $sender, Command $cmd, string $label, array $args) : bool{
      switch($cmd->getName()){
          case "comprar":
            if($args[0] === null){
              $sender->sendMessage("§5§lLoja §r§7para ver item da loja utilize: /comprar lista");
              return true;
          }
        if($args[0] === 1){
       switch ($args[1]){
       case "cow":
      //code
      break;
      }
}
          case "comprar lista":{
              $sender->sendMessage("§fCaixa Normal §7(200 De Cash)");
              $sender->sendMessage("§fCaixa Ultra §7(400 De Cash)");
              $sender->sendMessage("§fCaixa Master §7(600 De Cash)");
              $sender->sendMessage("§fUtilize /comprar key (normal,ultra,master)");
      return true;
          }
      }
    }

 

Here is giving error ne

PHP:

case "comprar":
            if($args[0] === null){


 

Try this?

PHP:

case "comprar":
          if(!isset($args[0])) {
 
          }

 

And to create a sub of /comprar example /comprar cow

 

$args is an array with the arguments of the command, what means if I type /buy thing 300, $args[0] is thing and $args[1] is 300.
Check if $args[0] equals to the argument desired and if it does, do whatever you want.

 

$args basically is an array
When you typed a command. For example:
/give BadderNTT dirt 2
So in this command
$cmd->getName() will return the name of the command (give)
$args is an array that every word behind the command's name is a value in this array
$args[0] is BadderNTT
$args[1] is dirt
$args[2] is 2
