Crockford Base32 encoding for PHP
=================================

[](#crockford-base32-encoding-for-php)

A simple and faithful implementation of Douglas Crockford's Base32 encoding in PHP as specified in . Supports encoding and decoding of up to 60-bit integers.

Usage
-----

[](#usage)

Encode and decode integers from 0 up to `1152921504606846975`(largest 60-bit). The full 60-65-bit range is not fully supported in a 64-bit system. The same applies to 30-35-bit range on a 32-bit system.

```
use Czarpino\PhpCrockford32\CrockfordBase32;

$crockfordBase32 = new CrockfordBase32();
$encoded = $crockfordBase32->encode(1152921504606846975); // ZZZZZZZZZZZZ
$decoded = $crockfordBase32->decode('ZZZZZZZZZZZZ');      // 1152921504606846975
```

### Encoding with Check Symbol

[](#encoding-with-check-symbol)

```
use Czarpino\PhpCrockford32\CrockfordBase32;

$crockfordBase32 = new CrockfordBase32();
$encoded = $crockfordBase32->encode(1152921504606846975);
$checksum = $crockfordBase32->checksum($number);
$encodedWithCheckSum = $encoded . $checksum;
```

### Decoding with Check Symbol

[](#decoding-with-check-symbol)

```
use Czarpino\PhpCrockford32\CrockfordBase32;

$encodedWithCheckSum = 'ZZZZZZZZZZZZ9';
$encoded = substr($encodedWithCheckSum, 0, -1);
$checksum = substr($encodedWithCheckSum, -1);

$crockfordBase32 = new CrockfordBase32();
$decoded = $crockfordBase32->decode($encoded);
$isValid = $checksum === $crockfordBase32->checksum($decoded);
```

Installation
------------

[](#installation)

```
composer require czarpino/php-crockford32
