Are there any best practices or guidelines for choosing between $_POST, $_GET, and $_REQUEST in PHP?

When choosing between $_POST, $_GET, and $_REQUEST in PHP, it is important to consider the sensitivity of the data being transmitted. Use $_POST for sensitive data like passwords or user inputs that need to be securely sent to the server. Use $_GET for non-sensitive data like search queries or pagination parameters that can be visible in the URL. Avoid using $_REQUEST as it combines both $_GET and $_POST data, which can lead to security vulnerabilities if not handled properly. 

// Example of using $_POST for sensitive data
$username = $_POST['username'];
$password = $_POST['password'];

// Example of using $_GET for non-sensitive data
$searchQuery = $_GET['query'];
$pageNumber = $_GET['page'];
