How can PHP be used to implement dynamic form input processing and output generation?

To implement dynamic form input processing and output generation in PHP, you can use the $_POST superglobal array to retrieve form data submitted by the user. You can then use this data to dynamically generate output or perform specific actions based on the user input. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Process the form data as needed
    // For example, you can output a customized message based on the user input
    echo "Hello, $name! Your email address is $email.";
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <label for="name">Name:</label>
    <input type="text" name="name" id="name">
    
    <label for="email">Email:</label>
    <input type="email" name="email" id="email">
    
    <input type="submit" value="Submit">
</form>
