What are the potential pitfalls of using cURL in PHP to fetch web pages?

One potential pitfall of using cURL in PHP to fetch web pages is that it may not handle redirects automatically, leading to potential issues with retrieving the desired content. To solve this problem, you can enable the `CURLOPT_FOLLOWLOCATION` option in your cURL request to allow it to automatically follow redirects. 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Enable automatic following of redirects

$response = curl_exec($ch);

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

curl_close($ch);
