Solved How to close chest head?

I can open a chest head using:

PHP:

/* getVector is returns vector that i needed */
/* $p instanceof Player */
$pack1 = new BlockEventPacket();
$pack1->x = $this->getVector(self::TYPE_CHEST1)->getFloorX();
$pack1->y = $this->getVector(self::TYPE_CHEST1)->getFloorY();
$pack1->z = $this->getVector(self::TYPE_CHEST1)->getFloorZ();
$pack1->eventType = 1;
$pack1->eventData = 2;
$p->dataPacket($pack1);

but how to close chest head? i'm incrementing eventType and eventData up to 30 but it doesnt closing anyway.
and is there a list of datas or types from mojang or something? where developers like @dktapps can take info about mcbe

 

well, thank everyone for helping find solution by myself:

PHP:

/* getVector is returns vector that i needed */
/* $p instanceof Player */
$pack1 = new BlockEventPacket();
$pack1->x = $this->getVector(self::TYPE_CHEST1)->getFloorX();
$pack1->y = $this->getVector(self::TYPE_CHEST1)->getFloorY();
$pack1->z = $this->getVector(self::TYPE_CHEST1)->getFloorZ();
$pack1->eventType = 1;
$pack1->eventData = 0;
$p->dataPacket($pack1);
