Hexdump utility for PHP. Print binary data in a similar format to the hexdump (hd) command line tool. Useful when debugging socket communications or handling binary files.

$ composer require jhartell/hexdump

Usage

<?php
use Jhartell\Hexdump\Hexdump;
$hexdump = new Hexdump();
$data = "This is a string with non-printable \x05\x10 characters\x00";
