Because mobile devices are limited by bandwidth and processor computing speed, they have higher requirements on web page performance. What elements in a webpage have slowed down the loading speed of a webpage on a mobile device? What should these elements do to improve the overall performance of pages on mobile devices? Is there a design mode that can meet the needs of both mobile and desktop page
PHP determines the source of a mobile device. PHP's method of judging the source of mobile devices is now in the hot age of mobile devices. maybe we often need to use page matching for mobile devices during web front-end development. Of course, we can use PHP to determine the source of mobile devices.
