Overview

Encodes and decodes arbitrary strings to and from Base62, the alphabet of digits and lower and upper case letters, which keeps the encoded value compact and safe in a URL. It backs the identifiers of ksuid.

Installation

composer require tiny-blocks/encoder

How to use

The library provides concrete implementations of the Encoder interface, enabling encoding and decoding of data into specific formats like Base62.

Using Base62

To encode a value into Base62 format:

<?php

declare(strict_types=1);

use TinyBlocks\Encoder\Base62;

$encoder = Base62::from(value: 'Hello world!');
$encoded = $encoder->encode();

# Output: T8dgcjRGuYUueWht

To decode a Base62-encoded value back to its original form:

<?php

declare(strict_types=1);

use TinyBlocks\Encoder\Base62;

$encoder = Base62::from(value: 'T8dgcjRGuYUueWht');
$decoded = $encoder->decode();

# Output: Hello world!

If you attempt to decode an invalid Base62 value, an InvalidDecoding exception will be thrown:

<?php

declare(strict_types=1);

use TinyBlocks\Encoder\Base62;
use TinyBlocks\Encoder\Exceptions\InvalidDecoding;

try {
    $encoder = Base62::from(value: 'invalid_value');
    $decoded = $encoder->decode();
} catch (InvalidDecoding $exception) {
    echo $exception->getMessage();
    # Output: The value <invalid_value> could not be decoded.
}
