Setting blocks in a radius of another

As the title said I would like to know how to set a block in a radius of another blick. I tried $block->x + 1 but i want it to form like a square around the block

 

PHP:

$radius = 1;
for ($x = -$radius; $x <= $radius; $x++) {
       for ($y = -$radius; $y <= $radius; $y++) {
              for ($z = -$radius; $z <= $radius; $z++) {
                     $block->getLevel()->setBlock($block->add($x, $y, $z), Block::get($id, $meta);
              }
       }
}

 

PHP:

/** @var Block $block */
foreach($block->getAllSides() as $pos){
    $block->getLevel()->setBlock($pos, Block::get(int, int));
}


NOTE: $pos is actually a Block instance whichwhich indir extends Vector3. Also, you may want to set the fourth parameter of Level::setBlock() as false to disallow any block updates from happening. Level::setBlock($pos, $block, false, false);

 

Hey it worked, but it spawns like this

x
xox
x

But I want it to spawn like

XXX
XoX
XXX

 

Oh I see, try:

PHP:

foreach(array_merge(
    [
        $block->add(1, 0, 1),
        $block->add(-1, 0, -1),
        $block->add(1, 0, -1),
        $block->add(-1, 0, 1)
    ],
    $block->getAllSides()
) as $pos){
]


But in that case, its better to use @DaPigGuy's with an exception to not loop through the main (center) block.
