How does PHP handle form data submission using POST and GET methods?

When handling form data submission in PHP, the POST method is typically used to send data securely, while the GET method sends data through the URL. To handle form data submission using POST, you can access the form data through the $_POST superglobal array, while for the GET method, you can use the $_GET superglobal array. 

// Handling form data submission using POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Process the form data as needed
}

// Handling form data submission using GET method
if ($_SERVER["REQUEST_METHOD"] == "GET") {
    $searchTerm = $_GET['search'];
    
    // Process the form data as needed
}
