How can the use of cURL in PHP improve the process of handling redirects when scraping website content?

When scraping website content, handling redirects can be crucial to ensure that the correct content is being retrieved. Using cURL in PHP allows for more control over the request process, including following redirects automatically. This can streamline the scraping process and ensure that the desired content is obtained without manual intervention. 

$url = 'http://example.com';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

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

curl_close($ch);

// Process $response as needed
