How can PHP be used to dynamically generate and display different forms based on user input in a web application?

To dynamically generate and display different forms based on user input in a web application using PHP, you can use conditional statements to determine which form to display based on the user input. By checking the user input, you can dynamically generate the form HTML code and display it to the user. 

<?php
if(isset($_POST['user_input'])){
    $user_input = $_POST['user_input'];
    
    if($user_input == 'form1'){
        // Display Form 1
        echo "<form action='process_form1.php' method='post'>";
        echo "<input type='text' name='input1'>";
        echo "<input type='submit' value='Submit'>";
        echo "</form>";
    } elseif($user_input == 'form2'){
        // Display Form 2
        echo "<form action='process_form2.php' method='post'>";
        echo "<input type='text' name='input2'>";
        echo "<input type='submit' value='Submit'>";
        echo "</form>";
    } else {
        echo "Invalid input";
    }
}
?>
