Saving item to config.

I'm aiming to save $item's id, damage, count and tags to a json config (hoping json is the right one to use here, yaml has problems with "\n" in item names).

Here's me code:

PHP:

public function saveItemToConfig(Item $item) {
$toJson = $item->jsonSerialize();
$cfg = new Config($this->getDataFolder().'config.json', Config::JSON);
$cfg->set('item', $toJson);
$cfg->save();
}

public function giveItemFromConfig(Player $player) {
$cfg = new Config($this->getDataFolder().'config.json', Config::JSON);
$json = $cfg->get('item', $toJson);
$item = Item::get($json["id"], $json["damage"], $json["count"], $json["nbt"]);
$player->getInventory()->addItem($item);
}


This is what I execute...

PHP:

$item = $player->getInventory()->getItemInHand();
$this->saveItemToConfig($item);
//later...
$this->giveItemFromConfig($player);


The code did work, but at times, when the item name had 3+ line breaks, it would just clear the 'item' value from $cfg, and return a null error when I'd execute $this->giveItemFromConfig($player);
Any help?

EDIT: YAML is bad. You can get yaml_emit no memory errors with it.

 

Okay, weird. Better.
Config::SERIALIZED does the trick.
You can directly save $item and then $player->getInventory()->addItem($configdata).
No nbtSerialize, jsonSerialise etc. Simple and straight. And works without these errors. Smooth, I'd say.

 

Did u make directory using @mkdir?

 

Try replacing "\n" with something else temporarily using str_replace() when you save the item. For example: str_replace("[BREAK]", "\n", $toJson)
When you give the item back then replace it back. Example: str_replace("\n", "[BREAK]", $item_name)

 

Of course.

Well, thanks, but I've already managed to fix it using serialized config...
This might be helpful to the future visitors...

CODE:

PHP:

public function saveItemToConfig(Item $item) {
$cfg = new Config($this->getDataFolder().'config.sl', Config::SERIALIZED);
$cfg->set('item', $item);
$cfg->save();
}

public function giveItemFromConfig(Player $player) {
$cfg = new Config($this->getDataFolder().'config.sl', Config::SERIALIZED);
$item = $cfg->get('item');
$player->getInventory()->addItem($item);
}


Executing..

PHP:

$item = $player->getInventory()->getItemInHand();
$this->saveItemToConfig($item);
$this->giveItemFromConfig($player);


PHP's serializing works perfectly for saving items.
