Bitly is one of the most powerful and popular URL shorten and bookmark service in the universe. Bitly offers simple and powerful API to generate short URL from long one. To use this API you have to signup for an API key. Bitly offers it free for it's all users. If you want, you can get it from Bitly's home page. Here's an example to create a short URL using PHP.




The Bitly Class:
class Bitly
{
	var $apiURL = 'http://api.bit.ly/v3/';
	var $apiQuery = '';

	/**
	 * @param str $login as Bitly login
	 * @param str $apiKey as Bitly API Key
	 */
	function __construct($login, $apiKey)
	{
		$this->apiQuery = 'login=' . $login;
		$this->apiQuery .= '&apiKey=' . $apiKey;
		$this->apiQuery .= '&format=json';
	}

	/**
	 * Short Long URL
	 * @param string URL
	 * @return string || void
	 */
	function shorten($uri)
	{
		$this->apiQuery .= '&uri=' . urlencode($uri);
		$query = $this->apiURL . 'shorten?' . $this->apiQuery;
		$data = $this->curl($query);
		$json = json_decode($data);
		return isset($json->data->url) ? $json->data->url : '';
	}

	/**
	 * Expend Short URL
	 * @param str URL
	 * @return str || void
	 */
	function expend($uri)
	{
		$this->apiQuery .= '&shortUrl='.urlencode($uri);
		$query = $this->apiURL . 'expand?' . $this->apiQuery;
		$data = $this->curl($query);
		$json = json_decode($data);
		return isset($json->data->expand[0]->long_url) ? $json->data->expand[0]->long_url : '';
	}

	/**
	 * Send CURL Request
	 * @param string URL
	 * @return string
	 */
	function curl($url)
	{
		$ch = curl_init();
		curl_setopt($ch, CURLOPT_URL, $url);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
		$data = curl_exec($ch);
		curl_close($ch);
		return $data;
	}
}

Usage:
# Include main bitly class
include 'bitly.php';
# Bitly User Login
$login = 'my-bitly-login';
# Bitly API key
$api = 'my-bitly-api-key';

$bitly = new Bitly($login, $api);
# Shorten Long URL
$bitly->shorten('http://www.w3bees.com');
# Expend Short URL
$bitly->expend('http://bit.ly/15MCr0p');

  3. Did you know you can shorten your long links with AdFly and make dollars for every visit to your shortened urls.

  4. But you have a domain name and you've decided to repurpose that site for some of your offers or products. Use a URL shortener to help avoid turning people off just due to the domain name. This can help you keep moving forward until you are ready or able to buy another domain name that suits your marketing efforts better. url shortener

  5. General it seems, by all accounts, to be a legitimate procedure, however I can't shake the sentiment of strolling through a third world market endeavoring to fend off my wallet from some person's pet monkey. The yearly expense is ~$75/yr. url shortener

  6. Maybe their most serious issue is that is doesn't resemble a URL by any stretch of the imagination. link shortener

  7. A url shortener is a Website that will create a short Uniform Resource Locator (URL) or Web page address from a long one so that the short version, which is easier to remember and enter, can be used instead.
