How can PHP developers effectively handle data passed through forms in PHP when using both POST and GET methods?

When handling data passed through forms in PHP using both POST and GET methods, developers can effectively use the $_REQUEST superglobal array to access data regardless of the method used. This allows for flexibility in retrieving form data without needing to differentiate between POST and GET methods. 

// Example of handling form data using $_REQUEST superglobal
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_REQUEST['username'];
    $password = $_REQUEST['password'];
    // Process form data
} elseif ($_SERVER["REQUEST_METHOD"] == "GET") {
    $searchQuery = $_REQUEST['search_query'];
    // Process form data
}
