There is a link for example site.ru/index.php?url=312

When you click on it throws for example an some site2.ru

How to programmatically determine the url address of this site2.ru

Google hour did not give anything, I do not even know which way to dig.

Find out the address where the redirect occurs, for example: I have a link http://vk.cc/cObdk when clicking on it will forward me to the main page of the hashcode, I need to pass a parameter to the script, for example $ url = "http: // vk. cc / cObdk "; he gave me $ endurl = "http://hashcode.ru/";

I tried this:

$ch = curl_init(); //GET запрос указывается в строке URL curl_setopt($ch, CURLOPT_URL, $pley[1]); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); //curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30); curl_setopt($ch, CURLOPT_REFERER, 'http://сайт.com/'); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; rv:6.0.2) Gecko/20100101 Firefox/6.0.2'); $endurl = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL); $data = curl_exec($ch); curl_close($ch);

But in the end I get the source address, not the final one.

 $url = array ( 'blabla' => 'site.ru', 'ololo' => 'example.com' ); if(isset($_GET['url'])) { if(isset($url[$_GET['url']])) { echo 'Redirect url: ' . $url[$_GET['url']]; } else { echo 'URL Not Found'; } } //?index.php?url=blabla => site.ru //?index.php?url=ololo => example.com

All the same can be done when querying the database.

UPD

 CREATE TABLE `redirect` ( `id` int(11) NOT NULL auto_increment, `short_code` varchar(255) NOT NULL, `url` varchar(255) NOT NULL, PRIMARY KEY(`id`), UNIQUE KEY(`short_code`) ); INSERT INTO `redirect` VALUES('1', 'ololo', 'example.com'); if(isset($_GET['url'])) { $query = musql_query("SELECT * FROM `redirect` WHERE `short_code` = '".$_GET['url']."'"); //Дальше сами) } 
     $url = 'http://google.com'; $headers = get_headers($url, 1); print "<pre>"; print_r($headers['Location']);

      In general, this URL honestly gives 302:

       wget -S "http://vk.cc/cObdk" --15:58:47-- http://vk.cc/cObdk => `cObdk' Resolving vk.cc... done. Connecting to vk.cc[93.186.228.129]:80... connected.

      See what you have in CURLINFO_HTTP_CODE. If something is different, then something is wrong somewhere :) Yes, and enable CURLOPT_HEADER and see what comes up in the headers.

         $endurl = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
