What are the implications of using CURLOPT_NOBODY in PHP requests?

When using CURLOPT_NOBODY in PHP requests, the server will only fetch the headers of the response and not the body content. This can be useful for checking the response headers without downloading the entire content, which can save bandwidth and improve performance. However, it's important to note that some servers may not support HEAD requests, which can result in unexpected behavior or errors. 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com');
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

if($response === false) {
    echo 'Error: ' . curl_error($ch);
} else {
    // Process response headers
    $headers = curl_getinfo($ch);
    var_dump($headers);
}

curl_close($ch);
