Text and integers encoding utilities for PHP with no extensions dependencies. Base32, Base58, Base64 and much more!
PHP is a great language but unfortunately provides us with only one text encoding (base64) which even not URL safe. And there are no straight way to change its alphabet.
BaseN solves that problem and implements common binary-to-text algorithm for encodings whose alphabet fully covers number of bits that corresponds its length. And rough algorithm which will encode each byte separately, it is less compact but guarantee the encoding with given alphabet.
Furthermore it gives you methods to encode and decode integers themselves instead of their text representation.
- PHP 7.1+
Install with composer
composer require xobotyi/basen
use xobotyi\basen\BaseN; use xobotyi\basen\Base58; // use it for something usual $base8 = new BaseN('01234567', false, false, false); echo $base8->encode(16) . "\n"; // 142330 echo $base8->encodeInt(16) . "\n"; // 20 // or create your own encoder with own alphabet if needed $myOwnEncoder = new BaseN('a123d8e4fiwnmqkl', false, true, true); echo $myOwnEncoder->encode(16) . "\n"; // 313e echo $myOwnEncoder->encodeInt(16) . "\n"; // 1a // predefined encoder echo Base58::encode(16) . "\n"; // 3hC // or, with alternative alphabet echo Base58::encode(16, Base58::ALPHABET_RIPPLE) . "\n"; // hkD echo Base58::encodeInt(16) . "\n"; // G
BaseN provides few classes implementing most popular encodings:
