What are the limitations of using PHP for responsive design compared to CSS?

One limitation of using PHP for responsive design compared to CSS is that PHP is server-side, meaning it cannot dynamically adjust styles based on screen size like CSS can. To address this limitation, you can use PHP to generate CSS media queries based on screen size and then include those styles in your HTML output.

<?php
// Define breakpoints for responsive design
$breakpoints = array(
    'small' => 576,
    'medium' => 768,
    'large' => 992,
    'xlarge' => 1200
);

// Generate CSS media queries based on screen size
echo '<style>';
foreach ($breakpoints as $key => $value) {
    echo "@media (min-width: {$value}px) {";
    // Add your responsive styles here
    echo '}';
}
echo '</style>';
?>
