As a beginner in PHP, what are some key considerations to keep in mind when expanding functionality to include additional form fields in a dynamic image generation script?

When expanding functionality to include additional form fields in a dynamic image generation script, it is important to properly handle the form data submitted by the user and update the image generation logic accordingly. This may involve modifying the existing PHP script to include the new form fields, validating the input data, and dynamically generating the image based on the user's selections. 

<?php
// Retrieve form data
$field1 = $_POST['field1'];
$field2 = $_POST['field2'];
$field3 = $_POST['field3'];

// Validate input data
// Add validation logic here

// Generate image based on form fields
// Modify image generation logic to include new fields

// Output the generated image
?>
