<?php
class BitBuffer{

	/** @var int[] */
	public array $buffer = [];

This code did not parse for me. Apparently, there is an error somewhere around this line:

Syntax error, unexpected T_ARRAY, expecting T_FUNCTION or T_CONST

	public int $length = 0;

	/**
	 *
	 */
	public function clear():BitBuffer{
		$this->buffer = [];
		$this->length = 0;

		return $this;
	}

	/**
	 *
	 */
	public function put(int $num, int $length):BitBuffer{

		for($i = 0; $i < $length; $i++){
			$this->putBit((($num >> ($length - $i - 1)) & 1) === 1);
		}

		return $this;
	}

	/**
	 *
	 */
	public function putBit(bool $bit):BitBuffer{
		$bufIndex = floor($this->length / 8);

		if(count($this->buffer) <= $bufIndex){
			$this->buffer[] = 0;
		}

		if($bit === true){
			$this->buffer[(int)$bufIndex] |= (0x80 >> ($this->length % 8));
		}

		$this->length++;

		return $this;
	}
