Trying To Stop Non-Builders From Placing/Breaking Blocks

Hello again people of PocketMine,

I'm creating a plugin that only allows players with a 'Builder' or 'Owner' rank to place/break blocks.
Here is the code so far...

PHP:

public function onBlockPlace(BlockPlaceEvent $event){
      
        $player = $event->getPlayer();
      
        if ($this->getRank($player) !== "Builder" || "Owner") {
            $event->setCancelled();
            $player->sendMessage("[CR] Only [Builders] can place blocks!");
        }
    }
  
    public function onBlockBreak(BlockBreakEvent $event){
      
        $player = $event->getPlayer();
      
        if ($this->getRank($player) !== "Builder" || "Owner") {
            $event->setCancelled();
            $player->sendMessage("[CR] Only [Builders] can break blocks!");
        }
    }         

So I thought this would work, and it does but it applies to everyone even Builders and Owners

How can I make it so only the ranks that are not Builders or Owners have this function applied to them.

BTW the second function isn't intended to be indented. Formatting XD

Why do you do it with rank and not op status ?

This wouldn't work because you are writing PHP (which is a computer language and not a natural human language). The compute will evaluate your expression by first looking at $this->getRank($player) !== "Builder" and come with a boolean, and then evaluate "Owner" which evaluates to a boolean true. Then it does the "||" which takes whatever was on the left with the true from the "Owner", which always results in true.

What you want is:

PHP:

        if ($this->getRank($player) !== "Builder" && $this->getRank($player) !== "Owner") {


Cheers! Works perfectly!

How do you add ranks and make ranks and stuff like that

But do you understand why this works? Why it's && and not ||?

Yeah it was a simple mistake || is the logical operator for 'OR' when in fact I needed to use the 'AND' operator which is && in PHP.
Cheers for all the help!

`and`, `or, `&&` and `||` all exist in PHP, with different priority.
