In the context of PHP programming, what are some common approaches to handling form submissions after selecting options from multiple dropdown lists?

When handling form submissions after selecting options from multiple dropdown lists in PHP, one common approach is to use the $_POST superglobal array to retrieve the selected values from each dropdown list. You can then process these values accordingly, such as storing them in a database or performing calculations based on the selected options. 

<?php
// Check if the form has been submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    
    // Retrieve selected values from dropdown lists
    $dropdown1 = $_POST["dropdown1"];
    $dropdown2 = $_POST["dropdown2"];
    $dropdown3 = $_POST["dropdown3"];
    
    // Process the selected values
    // For example, you can store them in a database or perform calculations
    
    // Redirect to a success page or display a success message
    header("Location: success.php");
    exit();
}
?>
