Why might it be necessary to specify the request method (e.g., POST) in a cURL request made with PHP, even when no data is being transferred?

When making a cURL request with PHP, specifying the request method (e.g., POST) is necessary even when no data is being transferred because the default request method is typically set to GET. By explicitly specifying the request method, you ensure that the server processes the request correctly. This is especially important when interacting with APIs or web services that require specific request methods for different actions. 

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://api.example.com/endpoint');
curl_setopt($ch, CURLOPT_POST, true); // Specify the request method as POST
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

curl_close($ch);

echo $response;
