diarmuidie/niceid

PHP library to generate short, non-sequential, URL-friendly hashes of incremental IDs. Similar to YouTube https://www.youtube.com/watch?v=dQw4w9WgXcQ and Bitly http://bit.ly/1D0CAzd URLs.

Developed by Diarmuid.

Features

• Non-sequential IDs (i.e. difficult, but not impossible, to guess the next one).
• URL friendly.
• No external dependencies.
• PSR-4 compatible.
• Compatible with PHP >= 5.4

Installation

You can install NiceID through Composer:

$ composer require diarmuidie/niceid

Usage

Generate an ID from a int:

require 'vendor/autoload.php';

use Diarmuidie\NiceID\NiceID;

$niceid = new NiceID('Some Random Secret Value');
echo $niceid->encode(123); // uSdqd

Notice that a secret is passed to the NiceID constructor. This secret is used to encode and decode the IDs. If the secret changes then IDs cannot be decoded.

Use the decode method to decode the NiceID back to an int.

echo $niceid->decode('uSdqd'); // 123

You can also change the min length of the NiceID (Defaults to 5 if not specified):

$niceid->setMinLength(10);
echo $niceid->encode(123); // uccccccu8p

To specify the characters to use in the encoded string use the setCharacters() method.

$niceid->setCharacters('abcde');
echo $niceid->encode(123); // adcce

The default character set is: 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_

You can even specify a UTF-8 character set if you want:

$niceid->setCharacters('ⓐⓑⓒⓓⓔⓕⓖⓗⓘⓙⓚⓛⓜⓝⓞⓟⓠⓡⓢⓣⓤⓥⓦⓧⓨⓩ');
echo $niceid->encode(123); // ⓖⓑⓥⓘⓘⓠ

To Do

• Add library to packagist.
• Setup Travis to run unit tests.
• Better handle UTF-8 chars in character string.
• 100% Code coverage for unit tests.
• Refactor BaseConvert::convert() method.
• Handle PHP_INT_MAX overflow.
• Implement BCMath support for integers larger than PHP_INT_MAX.
