What are the potential pitfalls of manually following redirects in PHP when reading website content?

When manually following redirects in PHP when reading website content, potential pitfalls include an increased risk of infinite redirect loops, slower performance due to multiple HTTP requests, and potential security vulnerabilities if the redirects are not properly validated. To solve this issue, it is recommended to use a library or function that handles redirects automatically, such as cURL or the `file_get_contents` function with the `allow_url_fopen` setting enabled. 

$url = 'https://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);
} else {
    echo $response;
}

curl_close($ch);
