How can PHP functions be utilized effectively to generate and manage form outputs in a structured manner?

To generate and manage form outputs in a structured manner using PHP functions, you can create reusable functions for common form elements such as input fields, select dropdowns, radio buttons, checkboxes, etc. These functions can accept parameters to customize the output based on the specific form requirements. By organizing your form generation code into functions, you can easily maintain and update the form structure without duplicating code. 

<?php
// Function to generate input field
function generateInputField($name, $label, $type = 'text', $value = '') {
    $html = '<label for="' . $name . '">' . $label . '</label>';
    $html .= '<input type="' . $type . '" name="' . $name . '" id="' . $name . '" value="' . $value . '">';
    return $html;
}

// Function to generate select dropdown
function generateSelectDropdown($name, $label, $options, $selected = '') {
    $html = '<label for="' . $name . '">' . $label . '</label>';
    $html .= '<select name="' . $name . '" id="' . $name . '">';
    foreach ($options as $key => $option) {
        $html .= '<option value="' . $key . '" ' . ($selected == $key ? 'selected' : '') . '>' . $option . '</option>';
    }
    $html .= '</select>';
    return $html;
}

// Example usage
echo generateInputField('username', 'Username');
echo generateSelectDropdown('country', 'Country', ['US' => 'United States', 'CA' => 'Canada', 'UK' => 'United Kingdom'], 'US');
?>
