Comment puis-je obtenir le deuxième lien du premier?
J'ai essayé cela mais ne fonctionne pas, me renvoyant le même premier lien:

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$a = curl_exec($ch);
print_r($a);echo"<br>";
if(preg_match('#Location: (.*)#', $a, $r)){
$l = trim($r[1]);
echo $l;

Merci beaucoup.
Merci à @ king-isaac le code suivant a été testé et cela fonctionne.

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Must be set to true so that PHP follows any "Location:" header
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$a = curl_exec($ch); // $a will contain all headers
$url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL); // This is what you need, it will return you the last effective URL
// Uncomment to see all headers
/*
echo "<pre>";
print_r($a);echo"<br>";
echo "</pre>";
*/
echo $url; // Voila

Vous pouvez obtenir l'URL finale d'une demande avec curl_getinfo .
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
$url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
Vous pouvez le faire sans utiliser CURL. Rendu simple et court.
