How can developers effectively debug and validate the generated HTML output from PHP scripts for form generation?

To effectively debug and validate the generated HTML output from PHP scripts for form generation, developers can use tools like browser developer tools to inspect the generated HTML code, validate the HTML using online validation tools, and use PHP functions like `htmlspecialchars()` to prevent XSS attacks and ensure proper encoding of special characters in the generated HTML. 

<?php
// Sample PHP script for form generation
$form_data = array(
    'name' => 'John Doe',
    'email' => 'john.doe@example.com'
);

echo '<form>';
foreach ($form_data as $key => $value) {
    echo '<label for="' . $key . '">' . ucfirst($key) . ':</label>';
    echo '<input type="text" id="' . $key . '" name="' . $key . '" value="' . htmlspecialchars($value) . '"><br>';
}
echo '<input type="submit" value="Submit">';
echo '</form>';
?>
