Why this is not working?

This code should spawn the structure, but it will only spawn one block

PHP:

public function spawnStructure(Vector3 $pos, Level $lv, int $id) : void{
        $structure=$this->getStructure($id);
        $blocks=$structure->getBlocks();
        foreach($blocks as $blstr){
            $arr=explode(',', $blstr);
            $x=str_replace("x", $pos->getX(), $arr[0]);
            $y=str_replace("y", $pos->getY(), $arr[1]);
            $z=str_replace("z", $pos->getZ(), $arr[2]);
            $lv->setBlock(new Vector3($x, $y, $z), Block::get($arr[3]));
        }
    }

blocks array be like:
["x, y+1, z-1, 54"]

I m really dont know why this is not working.
Thanks for help

 

What did you want the code to do? What did the code actually do?

 

This code should spawn the structure, but it will spawn only one block of all (the last one), the getBlocks () function returns an array of blocks that looks something like this:
["x, y+1, z, 54", "x-2, y, z, 87", "x, y, z, 56"]

 

It doesnt evaluate the expression string, Im surprised you can even run that code
You cant pass something like "5+1" when it expects an int, it wont do the addition for you

 

How to fix this ?
