What are the differences between accessing data using $_POST and $_GET in PHP scripts?

When accessing data in PHP scripts, the main difference between $_POST and $_GET is how the data is sent. $_POST sends data through the HTTP request body, while $_GET sends data through the URL. $_POST is more secure for sensitive data as it is not visible in the URL, while $_GET is commonly used for retrieving data from the server. 

// Using $_POST to access data
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    
    // Process the data
}
