I\'m trying to get url links to those bit.ly redirects. I\'ve tried to open bit.ly links with file_get_contents but it already gets content from redirected site
You can query bit.ly's API (documentation) for the long URL. You will need your username and API key (which can be found on your account page).
$endpoint = 'http://api.bit.ly/v3/expand?';
$params = array(
'shortUrl' => 'http://bit.ly/aUmUDq',
'login' => 'your_bitly_username',
'apiKey' => 'your_api_key',
'format' => 'txt'
);
$api_url = $endpoint . http_build_query($params);
echo file_get_contents($api_url);
