## About YOURLS

### What is YOURLS

YOURLS stands for Your Own URL Shortener. It is a small set of PHP scripts that will allow you to run your own URL shortening service (a la TinyURL or bitly).

Running your own URL shortener is fun, geeky and useful: you own your data and don't depend on third party services. It's also a great way to add branding to your short URLs, instead of using the same public URL shortener everyone uses.

### YOURLS Features

- `Free` and `Open Source` software.
- `Private` (your links only) or `Public` (everybody can create short links, fine for an intranet)
- Sequential or custom URL keyword
- Handy `bookmarklets` to easily shorten and share links
- Awesome `stats`: historical click reports, referrers tracking, visitors geo-location
- Neat `Ajaxed` interface
- Terrific `Plugin` architecture to easily implement new features
- Cool developer `API`
- Full `jsonp` support
- Friendly `installer`
- `Sample files` to create your own public interface and more

## Configuration (in `user/config.php`)

### MySQL settings

- `YOURLS_DB_USER`
  your MySQL username
  Example: `define( 'YOURLS_DB_USER', 'joe' );`
- `YOURLS_DB_PASS`
  your MySQL password
  Example: `define( 'YOURLS_DB_PASS', 'MySeCreTPaSsW0rd' );`
- `YOURLS_DB_NAME`: The database name
  Example: `define( 'YOURLS_DB_NAME', 'yourls' );`
- `YOURLS_DB_HOST`
  The database host
  Example: `define( 'YOURLS_DB_HOST', 'localhost' );`
- `YOURLS_DB_PREFIX`
  The name prefix for all the tables YOURLS will need
  Example: `define( 'YOURLS_DB_PREFIX', 'yourls_' );`

### Site options

- `YOURLS_SITE`
  Your (hopefully short) domain URL, no trailing slash, lowercase. If you pick the non-www version of your domain, don't use the www version in your browser (and vice-versa)
  Example: `define( 'YOURLS_SITE', 'http://ozh.in' );`
- `YOURLS_HOURS_OFFSET`
  Timezone GMT offset
  Example: `define( 'YOURLS_HOURS_OFFSET', '-5' );`
- `YOURLS_PRIVATE`
  Private means the admin area will be protected with login/pass as defined below. See Private or Public for more.
  Example: `define( 'YOURLS_PRIVATE', 'true' );`
- `YOURLS_UNIQUE_URLS`
  Allow multiple short URLs for a same long URL
  Set to `true` to allow only one pair of shortURL/longURL (default YOURLS behavior), or to `false` to allow creation of multiple short URLs pointing to the same long URL (as bit.ly does)
  Example: `define( 'YOURLS_UNIQUE_URLS', 'true' );`
- `YOURLS_COOKIEKEY`
  A random secret hash used to encrypt cookies. You don't have to remember it, make it long and complicated. Hint: generate a unique one at http://yourls.org/cookie
  Example: `define( 'YOURLS_COOKIEKEY', 'qQ4KhL_pu|s@Zm7n#%:b^{A[vhm' );`
- `yourls_user_passwords`
  A list of username(s) and password(s) allowed to access the site if private
  Passwords can either be in plain text, or encrypted: see http://yourls.org/userpassword for more information.
  Example: `'joe' => 'mypassword'`

### URL Shortening settings

- `YOURLS_URL_CONVERT`
  URL shortening method: base `36` or `62`. See FAQ for more explanations
- `yourls_reserved_URL`
  A list of reserved keywords that won't be used as short URLs. Define here negative, unwanted or potentially misleading keywords
  Example: `'porn', 'faggot', 'sex', 'nigger', 'fuck', 'cunt', 'dick'`

### Optional settings

- `YOURLS_PRIVATE_INFOS`
  If `YOURLS_PRIVATE` is set to `true`, you can still make stat pages public. To do so, define with:
  `define('YOURLS_PRIVATE_INFOS', false);`
- `YOURLS_PRIVATE_API`
  If `YOURLS_PRIVATE` is set to `true`, you can still make your API public. To do so, define with:
  `define('YOURLS_PRIVATE_API', false);`
- `YOURLS_NOSTATS`
  If `YOURLS_NOSTATS` is set to `true`, redirects won't be logged and there will be not stats available.

### Advanced settings

- YOURLS will look for the MySQL extension PDO, MySQLi or MySQL, in that order. If you want to force usage of one particular extension, add the following line to your `config.php`:
  `define( 'YOURLS_DB_DRIVER', 'mysqli' );`
- You can install YOURLS behind a firewall or a proxy: see Proxy Support
- File `includes/load-yourls.php` contains a few more undocumented but self explanatory and commented settings. Add them to your own `config.php` if you know what you're doing.

## Plugins for YOURLS

### Plugins?

Plugins are additional PHP scripts that extend the functionalities or features of YOURLS. The core of YOURLS is designed to be as light as possible and avoid bloat (implementing functions not everybody needs) and to allow for easy customization.

Using the plugin architecture, you can add new features to YOURLS without having to modify core files. This way, your changes won't be lost when you upgrade your YOURLS installation and you can easily activate and deactivate a plugin from the admin interface.

There's a growing number of plugins available: check the Plugin list.

### Documentation

Several sample plugins are included in the archive. Read the source and learn the concept. It's easy and fun!

Check the plugin API documentation to learn more

## YOURLS' API

### Features

- Generate or get existing short URLs, with sequential or custom keyword
- Get some statistics about your links: top clicked links, least clicked links, newest links
- Output format: JSON, XML, or simple raw text
- Authentify either with login/password or using a secure passwordless mechanism

### Usage

You need to send parameters to `http://your-own-domain-here.com/yourls-api.php` either via `GET` or `POST` (remember to URL encode parameters if via GET). These parameters are:

- A valid `username` / `password` pair, or your `signature` (see Passwordless API requests)
- The requested `action`: `"shorturl"` (get short URL for a link), `"expand"` (get long URL of a shorturl), `"url-stats"` (get stats about one short URL), `"stats"` (get stats about your links) or `"db-stats"` (get global link and click count)
- With `action = "shorturl"` :
  - the `url` to shorten
  - optional `keyword` and `title` for custom short URLs
  - output `format`: either `"jsonp"`, `"json"`, `"xml"` or `"simple"`
- With `action = "expand"` :
  - the `shorturl` to expand (can be either 'abc' or 'http://site/abc')
  - output `format`: either `"jsonp"`, `"json"`, `"xml"` or `"simple"`
- With `action = "url-stats"` :
  - the `shorturl` for which to get stats (can be either 'abc' or 'http://site/abc')
  - output `format`: either `"jsonp"`, `"json"` or `"xml"`
- With `action = "stats"` :
  - the `filter`: either `"top"`, `"bottom"` , `"rand"` or `"last"`
  - the `limit` (maximum number of links to return)
  - output `format`: either `"jsonp"`, `"json"` or `"xml"`
- With `action = "db-stats"` :
  - output `format`: either `"jsonp"`, `"json"` or `"xml"`

### Sample requests

Example of a `GET` request with Javascript (using jQuery) to shorten a URL

    var api_url  = 'http://sho.rt/yourls-api.php';
    var response = $.get( api_url, {
        username: "your_username",
        password: "your_password",
        action:   "shorturl",
        format:   "json",
        url:      "http://ozh.org/"
        },
        // callback function that will deal with the server response
        function( data) {
            // for instance, return short URL
            return data.shorturl;
        }
    );

Example of a `POST` request with PHP to expand a short URL

    <?php
    $username = 'your_username';
    $password = 'your_password';
    $api_url =  'http://sho.rt/yourls-api.php';

    // Init the CURL session
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $api_url);
    curl_setopt($ch, CURLOPT_HEADER, 0);            // No header in the result
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return, do not echo result
    curl_setopt($ch, CURLOPT_POST, 1);              // This is a POST request
    curl_setopt($ch, CURLOPT_POSTFIELDS, array(     // Data to POST
            'shorturl' => 'ozh',
            'format'   => 'json',
            'action'   => 'expand',
            'username' => $username,
            'password' => $password
        ));

    // Fetch and return content
    $data = curl_exec($ch);
    curl_close($ch);

    // Do something with the result. Here, we echo the long URL
    $data = json_decode( $data );
    echo $data->longurl;

### Sample returns

Sample return in JSON format for the `shorturl` action

      "url": {
        "keyword": "ozh",
        "url": "http:\/\/ozh.org",
        "title": "Ozh RICHARD \u00ab ozh.org",
        "date": "2014-10-24 16:01:39",

        <keyword>ozh</keyword>
        <shorturl>http://sho.rt/ozh</shorturl>
        <longurl>http://ozh.org/</longurl>
        <message>success</message>
        <statusCode>200</statusCode>
    </result>

### Sample file

There's a sample PHP file included that serves as an example on how to play with the API

### Expand the API

You can easily implement custom API actions with a plugin. See the plugin list for examples.

## FAQ

### Server requirements

1. A server with mod_rewrite enabled
2. At least PHP 5.3
3. At least MYSQL 5
4. Note: YOURLS can also run on Nginx and Cherokee

### Server recommendations

- PHP CURL extension installed if you plan on playing with the API

### Limitations

- Maximum length of custom keyword is 200 characters
- That makes about 8 sexdecillions of centillions of available URLs (seriously. That's a 355 digits number).

### Difference Between Base 36 And Base 62 Encoding

- Base 36 encoding uses `0123456789abcdefghijklmnopqrstuvwxyz` for short URLs
- Base 62 encoding uses `0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz`
- Stick to one setting, don't change after you've created links as it will change all your short URLs!
- Base 36 is the default and should be picked if you're not sure.

### Getting a short domain name for your YOURLS install

- Unless you plan on making it public and as popular as bit.ly, any shared hosting will be fine. Ozh runs all his YOURLS instance on Dreamhost and it works just great.
- Domainr is a fun search tool that might inspire and help you
- Aim for exotic top level domains (.in, .im, .li ...), they're often cheap and a lot are still available. Gandi is a pretty comprehensive registrar, for instance.

### YOURLS needs its own .htaccess

- You cannot install YOURLS and, say, WordPress, in the same directory. Both need to handle URLs differently and need their own `.htaccess` file.
- If you want to install YOURLS on the same domain than your blog, give it its own (short) subdirectory, such as yourblog.com/s/ (for "short") or yourblog.com/x/ (for "exit")

### If YOURLS generates 404 for your short URLs

- Make sure mod_rewrite is enabled with your Apache server
- Make sure your .htaccess file looks like this one
- Eventually, check your server Apache configuration allows use of .htaccess (`AllowOverride All` directive, ask your server admin)

### Random versus sequential short URLs

- Out of the box, YOURLS generates sequential short URLS (ie `ab31`, then `ab32` and so on)
- If you prefer random short URLs (ie `j3kz1` then `13hz7` like Bitly does), just activate the plugin that comes with YOURLS.

### There is no index page at the root of the install

- Indeed. It's intended. It's up to the user to make what they need. Some will redirect the root to a different place, some make a public interface for anyone to shorten links, some make a portfolio. You make it.
- If you want to make a public interface and run your own little bitly.com, there's a sample file provided as an example: `sample-public-front-page.txt`. This implies important issues to deal with: spam, performance and security. Read Public Shortening for important information.

### Uppercase letters in short URLs are eaten up, eg "`OmgOzh`" becomes "`mgzh`" !

- Indeed. It's intented if you selected Base 36 (see above). Letters that don't belong to the character set, eg `@#!` or `ABC`, are removed.
- If you want to force lowercase, you'll need a plugin.

### Feedback, feature requests and bug reporting

1. Please don't get in touch directly by mail or Twitter. Please.
2. Check the Road Map for future features.
3. Read all the wiki documents.
4. Search in all the issues, open and closed.
5. Eventually raise a new issue. To do so, please read the contribute guidelines. Thanks!

## Community

YOURLS is open source, so the community of users plays a great role in its development, by contributing, helping others or giving feedback that helps improve the software.
