PHP binary base changer

Change raw binary bytes to and from an arbitrary base e.g. 36, 58, or 64. This package stands in place of PHP's native base_convert() function and in doing so provides support for arbitrarily large numbers.

Requirements

This package requires the GMP PHP extension to be installed.

Install

Via composer:

composer require davidfricker/basechanger

Usage

use DavidFricker\BaseChanger\GMP;

$bytes = openssl_random_pseudo_bytes(32);
$base = 64;

$base_converted = GMP::changeTo($bytes, $base);
$base_reversed = GMP::changeFrom($base_converted, $base);
