In the context of PHP cURL requests, what are the differences between passing parameters as a urlencoded string versus an array, and how does it impact API authentication?

When making cURL requests in PHP, passing parameters as a urlencoded string can be convenient for simple requests, but using an array allows for easier manipulation and maintenance of parameters. When it comes to API authentication, passing parameters as an array can make it easier to add authentication headers or tokens. It is recommended to use an array for parameters when dealing with API authentication to ensure proper handling of sensitive information. 

// Example of making a cURL request with parameters passed as an array for API authentication

$ch = curl_init();

$url = 'https://api.example.com/endpoint';
$params = [
    'param1' => 'value1',
    'param2' => 'value2',
    'api_key' => 'your_api_key_here'
];

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));

// Add authentication headers if needed
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Authorization: Bearer your_access_token_here'
]);

$response = curl_exec($ch);

curl_close($ch);

echo $response;
