A PHP port of Elixir's CustomBase module
Lets make Base12 module with conversion described below.
| Value | Encoding |
|---|---|
| 0 | 0 |
| 1 | 1 |
| 2 | 2 |
| 3 | 3 |
| 4 | 4 |
| 5 | 5 |
| 6 | 6 |
| 7 | 7 |
| 8 | 8 |
| 9 | 9 |
| 10 | A |
| 11 | B |
use Cartware\CustomBase\CustomBase; class Base12 { use CustomBase; protected const CUSTOMBASE_ALPHABET = '0123456789AB'; }Now your class has 2 functions encode/1 and decode/1:
$base12 = new Base12(); $base12->encode(9); # 9 $base12->encode(10); # A $base12->encode(11); # B $base12->encode(12); # 10 $base12->decode(16); # 18 $base12->decode('AB'); # 131Released under the MIT License.
