What are best practices for accessing and handling source code from redirected URLs using cURL?

When accessing and handling source code from redirected URLs using cURL, it is important to follow best practices to ensure proper handling of redirects and to retrieve the final destination URL's source code. One way to achieve this is by setting the CURLOPT_FOLLOWLOCATION option to true in the cURL request, which allows cURL to automatically follow any redirects and retrieve the final destination URL's source code. 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/redirected-url');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

$response = curl_exec($ch);

if($response === false){
    echo 'cURL error: ' . curl_error($ch);
} else {
    echo $response;
}

curl_close($ch);
