What are some best practices for optimizing websites for mobile devices in PHP development?

One best practice for optimizing websites for mobile devices in PHP development is to use responsive design techniques, such as using media queries to adjust the layout and styling based on the device's screen size. Another best practice is to minimize the use of large images and heavy scripts that can slow down the website loading time on mobile devices. 

// Example of using media queries in PHP to adjust styling for mobile devices
echo '<style>';
echo '@media only screen and (max-width: 600px) {';
echo '  body { font-size: 14px; }';
echo '}';
echo '</style>';
