How can I get the destination URL using cURL?

$url = "https://www.example.com";

// Initialize cURL session
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, $url); // initial URL
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return response as string
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow redirects

// Execute cURL session
$response = curl_exec($ch);

// Check for errors
if(curl_errno($ch)) {
    echo 'Error: ' . curl_error($ch);
}

// Get the final URL after following redirects
$finalUrl = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);

// Close cURL session
curl_close($ch);

// Process the response and final URL
echo "Response: " . $response . "<br>";
echo "Final URL: " . $finalUrl;
