How can PHP scripts be structured to handle user input and continue execution based on user actions?

To handle user input and continue execution based on user actions in PHP scripts, you can use conditional statements such as if, else if, and else to check the user input and perform different actions accordingly. You can also use loops to iterate through user input or perform actions multiple times based on user interactions.

<?php
// Get user input
$userInput = $_POST['user_input'];

// Check user input and perform actions
if ($userInput == 'action1') {
    // Perform action 1
} elseif ($userInput == 'action2') {
    // Perform action 2
} else {
    // Perform default action
}
?>
