Base65536 is a binary encoding optimised for UTF-32-encoded text and Twitter. This PHP composer package, phplang/base65536, is loosely based on qntm/base65536.

Usage

use \PhpLang\Base65536;

$buf = 'hello world';
$str = Base65536::encode($buf);
echo $str; // 6 codes points, '驨ꍬ啯𒁷ꍲᕤ'

var_dump($buf === Base65536::decode($str)); // bool(true)

Note

Per the spec, the default encoding used for input to decode() and output from encode() is CESU-8, a variant of UTF-8 which encodes split UTF-16 surrogate pairs. If you want true UTF-8 output, you must specify so using the second parameter to encode() and decode().
