Get all blocks by id

I want get all blocks by ID and next add a block near it.
I was trying to add multiple blocks to a .yml, but I think this is not easy, lol.
Can anyone help me?

well, i know how to set blocks. but, i do not understand where are you trying to set this block. and, do you know "blocks" is plural and "it" is singular , i' m confused
sorry, be more specific if you can

I know how to set a block,.
This is not the problem... the problem is that I'm trying to save multiple blocks (x,y,z,level) to a yml.

Code:

// Make a file for the island
            $islandFile = fopen($this->getDataFolder()."Islands/".$name.".txt", "w");
            fwrite($islandFile, $randX.", ".$Y.", ".$randZ);
            $playerFile = fopen($this->getDataFolder()."Players/".$name.".txt", "w");
            fwrite($playerFile, $player->getLevel()->getName());

tp player

Code:

$player->teleport(new Position($randX+4, $Y+10, $randZ+4, $this->getServer()->getLevelByName($levelName)));
            $player->sendMessage(TextFormat::GREEN . "Welcome to your new island");
            $player->sendMessage(TextFormat::GREEN . "If your island didn't spawn,");
            $player->sendMessage(TextFormat::GREEN . "Use /is delete");
            $player->sendMessage(TextFormat::GREEN . "Then make a new island");

Code:

elseif($args[0] == "home"){
                    if($sender->hasPermission("is") || $sender->hasPermission("is.command") || $sender->hasPermission("is.command.home")){
                        if(!(file_exists($this->getDataFolder()."Islands/".$sender->getName().".txt"))){
                            $sender->sendMessage("You don't have an island. Use /is create to make one");
                            return true;
                        }else{
                            $level = $this->getServer()->getLevelByName(yaml_parse_file($this->getDataFolder()."Players/".$sender->getName().".txt"));
                            if($level !== null){
                                $sender->sendMessage(TextFormat::GREEN."Teleporting to your island...");
                                if($sender->getLevel()->getName() !== $level->getName()){
                                    $sender->sendMessage("You are not in the same world as your island. Use ".TextFormat::YELLOW."/mw tp ".$level->getName().TextFormat::RESET." and try again");
                                    return true;
                                }else{
                                    sleep(5);
                                    $sender->teleport(new Vector3(yaml_parse_file($this->getDataFolder()."Islands/".$sender->getName().".txt")));
                                    $sender->sendMessage(TextFormat::GREEN."Done!");
                                    return true;
                                }
                            }

Kinda same thing see in first part it save XYZ and then on is home it check xyz and tp player there

-.-
is this a troll or what ?
do you know what you wrote or just copy paste?

only this? do you want to save some blocks in a file?
what about " I want get all blocks by ID and next add a block near it. " ?

to save blocks you should have a point to start saving
like A(1,2,3) . depending on what would you like to save (cube?) you can loop through blocks and save the coords and id of each block in an array like

PHP:

$array[]= array($x,$y,$z,$id,$meta);

at the end you can serialize the array and put it in a file

PHP:

file_put_contents($file, serialize($array));

blocks to save shouldn't be too much.
to set these saved blocks:

PHP:

foreach( unserialize(file_get_contents($file)) as $block){
Level->setBlock(new Vector3($block[0], $block[1],$block[2]), Block::get($block[3],$block[4]));
}

If I have a good method for save all blocks into a yml, is pretty easy add a block near it.

What blocks are you even talking about. All the blocks in a level? Your explanation is confusing.

Get all blocks with the same id and them add it to a yaml

Get blocks from where? A world?

again... do you know "blocks" is plural and "it" is singular !

IT WHO ?????

just check if the id is the same, if it is, save the block

PHP:

Level->getBlock(x,y,z)->getId()

...and same to what ?

That wouldn't work.

PHP:

$level->getBlock(new Vector3($x, $y, $z))->getId()

Why are you being salty? I was correcting your mistake, chill.

I think @AndrewBit is not asking for a code to copy-paste, he is asking for an explanation/advice to do that.I was tring to explain him how he can save blocks, surely he can't copy paste the code i wrote , is only to give him an idea, i can't help him anymore because he don't know how to explain what is tring to do.

sorry if you feel offended but, i was only tring to tell him he can use the getId() method to get the block id.I wrote it fastly, Vector3 is correct , you are right.

but

$level should be an instance of pocketmine/level/Level
, you don't defined it, andrew can't copy-paste

$x - $y - $z doesn't exists

a semicolon is needed at the end of the statement or the server will crash

do you think this is a competition? ok, you won... nothing

I wasn't competing but thanks for the prize

WHOOP WHOOP WINNER BING BING BING BING! WHOOP WHOOP.

Spoiler

Well, thanks Svile, but I'm trying to save a specific block (if id == any) on BlockPlaceEvent.
The real problem is that I don't know how to create an multidimensional array in my yaml (with coords and level).

... and sorry if the last day I didn't explain as well my question. I was a bit asleep. x)
