PHP classes to handle Minecraft NBT (Named Binary Tag) format.
PHP 5.4 at least.
For some features, higher version of PHP may be required.
To handle 64-bit tags (i.e. TAG_Long, TAG_Double), 64-bit Linux version of PHP 5.6.3+ or 64-bit PHP7 is required.
composer require anrdaemon/minecraft-nbt
Just grab the archive, untar it and include '.../classloader.php';.
It's MAGIC!
Can be found in separate repository.
