How can I find where I will be redirected using cURL?

To make cURL follow a redirect, use:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

Erm... I don't think you're actually executing the curl... Try:

curl_exec($ch);

...after setting the options, and before the curl_getinfo() call.

EDIT: If you just want to find out where a page redirects to, I'd use the advice here, and just use Curl to grab the headers and extract the Location: header from them:

$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_HEADER, true);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);$result = curl_exec($ch);if (preg_match('~Location: (.*)~i', $result, $match)) {   $location = trim($match[1]);}

Add this line to curl inizialization

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

and use getinfo before curl_close

$redirectURL = curl_getinfo($ch,CURLINFO_EFFECTIVE_URL );

es:

$ch = curl_init($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_BINARYTRANSFER, true);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,0); curl_setopt($ch, CURLOPT_TIMEOUT, 60);$html = curl_exec($ch);$redirectURL = curl_getinfo($ch,CURLINFO_EFFECTIVE_URL );curl_close($ch);

The answer above didn't work for me on one of my servers, something to to with basedir, so I re-hashed it a little. The code below works on all my servers.

$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_HEADER, true);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);$a = curl_exec($ch);curl_close( $ch ); // the returned headers$headers = explode("\n",$a);// if there is no redirection this will be the final url$redir = $url;// loop through the headers and check for a Location: str$j = count($headers);for($i = 0; $i < $j; $i++){// if we find the Location header strip it and fill the redir var       if(strpos($headers[$i],"Location:") !== false){        $redir = trim(str_replace("Location:","",$headers[$i]));        break;    }}// do whatever you want with the resultecho redir;
