A quick & dirty example without any error handling etc. - just to get
the idea:

<?php
$options = array(
	CURLOPT_URL => 'http://mydomain.example/foobar',
	CURLOPT_HEADER => true,
	CURLOPT_FOLLOWLOCATION => false,
	CURLOPT_RETURNTRANSFER => true
);

$ch = curl_init();
curl_setopt_array($ch, $options);
$result = curl_exec($ch);
$resultcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);

if($resultcode == 302)
	$redirect = curl_getinfo($ch, CURLINFO_REDIRECT_URL);
else
	$redirect = '';

echo 'Effective URL: '.$url.'<br/>';
echo 'HTTP result code: '.$resultcode.'<br/>';
echo 'Redirection: '.$redirect.'<br/>';

curl_close($ch);
?>

See in action at <http://arnowelzel.de/samples/curl-sample.php>

CURLINFO_REDIRECT_URL is not in the documentation but it was added in
PHP 5.3.7. Also see <http://php.net/ChangeLog-5.php>.

If this does not work for you (e.g. because you have an older PHP
version), you have to extract the location header "manually".

HTH
