How to get the original link from twitter?

Question

PHP

On twitter, all links look like t.co. Is it possible to get the original link programmatically? That is, follow it and find out where it redirects?

Answer 1

$url = 't.co/MCmDluFvEU';

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
$html = curl_exec($ch);
curl_close($ch);

preg_match('/replace\(\"(.*)\"\)/i', $html, $matches);
$link = '';
if(isset($matches[1])){
  $link = stripcslashes($matches[1]);
}

Something like this, and then to your taste, but the php_curl extension must be installed

Answer 2

$url = ' t.co ';
print_r(get_headers($url, 1));
