What best practices should be followed when handling cURL requests in PHP scripts to avoid authentication issues?

When handling cURL requests in PHP scripts, it is important to ensure that authentication credentials are properly included in the request headers to avoid authentication issues. This can be done by setting the CURLOPT_USERPWD option with the username and password for basic authentication. Additionally, using HTTPS for secure communication is recommended to protect sensitive information. 

$url = 'https://api.example.com/data';
$username = 'your_username';
$password = 'your_password';

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");

$response = curl_exec($ch);

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

curl_close($ch);

// Process the response data here
